Do you use Apple’s Mail application on your Mac? It’s a capable email application and one of its best features is that its abilities can be extended using plug-ins. These plug-ins let you customize Mail so it can better meet your preferences and needs. Here’s a list of 10 plug-ins for Mail that’ll let you increase your productivity.

MsgFiler lets you quickly file email messages into one of your existing Mailboxes (aka folders). Using either a menu command or a keyboard shortcut you can file a message into a folder. Simply type the first few characters of the mailbox’s name and select the desired mailbox from the list of matches.

GrowlMail temporarily displays a small notification window on your screen every time a new email message arrives. By glancing at this notification you can monitor your Inbox while you’re working in another application.

SpamSieve offers better spam protection then Mail’s built-in junk mail filter. It accomplishes this by using Bayesian filtering methods. It require some initial training, but it’s very effective.

MailAct-On is an incredibly robust plug-in which lets you use keyboard shortcuts to quickly file, label or flag incoming or outgoing mail messages. That is an over-simplified description of its capabilities. This video introduction http://www.indev.ca/MailActOn_files/Virtual%20Tour.mov and video review http://media.macworld.com/media/vodcast/mwvodcast75.mp4 will give you a more complete understanding of it’s capabilities.

MailTags  let’s you assign keywords, priorities, categories and due dates to actions mentioned in an email. It lets you escape the constraints of folders by allowing you to organize and find your messages by keyword or other metadata that you’ve assigned. Made by the same developers, Mail Act-On and MailTags can be used together or separately.

WideMail reconfigures Mail’s layout. It moves the message preview area from below the list of messages to the right of it. This layout uses your screen’s space more efficiently. Apple realized this layout was very popular so they made it the standard layout in version 5.0 of Mail which comes with Lion, Mac OS X 10.7

Attachment Tamer gives you control over Mail’s handling of attachments that you send. Be default, Mail will display an attachment, such as an image, in the body of the email that you’re composing. Attachment Tamer lets you change this behavior and send the image as a regular attachment instead.

MessageFont  lets you set Mail’s default font when you reply to or compose a new email message. Mail’s preferences appears to let you set the default font, but this affects only what you see, not what the recipient sees. MessageFont changes which font is seen by the recipient.

MissingAttachments scans an email message and notifies you if you have referred to an attachment, but forgotten to attach a file. Unfortunately this plug in hasn’t been updated to work with recent versions of Mail.

MailUnreadStatusBar displays an icon to the upper right corner of your screen which lists the number of unread email messages you have. You can customize it to track multiple folders. Its icon then displays a menu listing the unread message count for each selected folder and lets you go directly to any of the listed folders.

In my opinion, these are some of the best plug-ins for Mail, but you can read about dozens more at the Hawk Wings web site.

RSS is a convenient way to stay abreast of news stories or articles added to a particular web site. Rather then needing to visit your favorite web site over and over, you can use RSS to be notified when a new story or article has been added as well as read some or all of that article. I like to read my RSS feeds in my email application, Mail.

Below are instructions on how to add an RSS feed to Apple’s Mail application.

1. Open a web browser, like Safari and go to a web site that offers an RSS feed. I’ll use Tidbits.com as my example, so go to http://www.tidbits.com

2. In the right-hand end of the address field you’ll see an RSS icon as depicted in this picture. Click on the RSS icon.

3. If the web site offers ONLY 1 feed then the address of the feed will be listed. In this case, Tidbits.com offers 3 feeds so I choose the “Full Text Feed” and then see a window like this one:

4. Copy the feed address, feed://tidbits.com/feeds/tidbits.rss by highlighting it and selecting Copy from the Edit menu.

5. Open Mail and select “Add RSS Feeds” from the File menu.

6.In the Add RSS Feeds window select “Specify the URL for a feed” and then select Paste from the Edit menu to paste the feed address (aka the URL) into the field. Use the picture below as a guide.

7. Click the Add button.

8. In a few seconds, you’ll see the Tidbits feed listed on the left-hand window of the Mail window under the “RSS section” as depicted below. The number to the right of the RSS feed’s name is an indication of the number of unread articles.

9. If you have added a number of RSS feeds, then you may want to rename them so they sort in a particular order as I’ve done by adding number prefixes.

Have you ever wanted to report a bug or request a feature for an application made by Apple, Adobe or Microsoft? Each company offers you the opportunity to do just that. Use the following web page addresses to submit your bug reports or feature request.

Apple Product Feedback and Feature Request

Microsoft Product Feedback and Feature Request

Adobe Product Feedback and Feature Request

I should mention that you shouldn’t expect to receive any feedback when you fill-out one of these forms. I had a conversation with an Apple Store manager who mentioned that when he had visited Apple’s headquarters, he’d seen a room full of people who were reading and processing all of the feedback which they received.

Did you receive an email attachment named winmail.dat or winmail? Here’s a brief explanation of what this file is and instructions for opening this type of file.

Winmail.dat files are sent by people using Microsoft Outlook as their email application. Under certain circumstances Outlook will encode attached files, like Word or PDF files, in this winmail.dat

Mac users can open the winmail.dat file using a free application (donations accepted) and extract the files hiding inside. Unfortunately, this application has a goofy name which is TNEF’s Enough. I won’t bore you with an explain of this name, but if you care, you can read about it on the developer’s web site.

Here are instructions on how to open the winmail.dat file.

• Save your winmail.dat file on your Desktop.
• If you use Mac OS X 10.5 or 10.6 then download TNEF’s Enough ver 2.2. If you use OS X 10.4 or earlier then download TNEF’s Enough ver 2.0
• By clicking on one of these links you’ll download a .zip file which contains TNEF’s Enough inside. Your Mac should automatically open the .zip file so you should see TNEF’s Enough sitting in your Downloads folder.
• Move TNEF Enough into your Applications folder.
• Double-click it to open it and then go to the File menu and select Open…
• Select the winmail.dat file which you previously put on the Desktop.
• You’ll then see a window listing the embedded files which are the files that you actually want.
• Click on each file, one at a time, and click the Save button.
• Save these files to your Desktop or any other desired location.
• Quit TNEF’s Enough.

You’re done. You can now throw away the winmail.dat file since you’ve extracted all of the files from inside it.

If you’d like to read more about how and why this happens please read this Microsoft Support article or this other article. These articles also provide instructions that you can pass on to the Outlook user who sent you the winmail.dat file so he or she can make changes to no longer send you winmail.dat files. Essentially, they have to edit their record for you in their Contact list and indicate that you should only receive plain-text emails.

Did you know that Apple’s Mail application automatically builds a list of all recipients to whom you’ve sent email? I think it’s very useful to review this list a few times each year. By reviewing this list you can easily add useful email addresses to your Address Book and you can delete out-dated email addresses or addresses that contain typos.

Before we review this list, it’s important to understand how this list is used by Mail. When you are creating a new email message and you begin to type a person’s name or email address in the To: field you’re typically presented with a list of email addresses which match the letters that you’ve typed. This list of email addresses is a composite of email addresses from your Address Book as well as addresses listed in your Previous Recipients list.

If you ever made a typo in an email address and then sent the email message then this incorrect email address was likely added to your Previous Recipient list. By reviewing this list you can remove such undesirable email addresses.

To view your Previous Recipient list, open Mail, click on the Window menu and select Previous Recipient. You can search this list using the search field in the upper right corner. You can also sort this list by any of the columns listed: Name, Email, Last Used. You can also sort by the left-hand most column which is not named. This column indicates if the email address is saved in your Address Book. If it is then you’ll see an icon which resembles a rolodex card. If the address is not in your Address Book then this space will be blank. I like to sort by this column to find common recipient’s whose email addresses I want in my Address Book. I then select them and use the Add to Address Book button. If you don’t typically add people to your Address Book this can be a fast way to add a whole lot of people to your Address Book.

In order to remove an email address containing a typo, I often use the search field to locate it. Then, I’ll click on it to select it and then use the Remove From List button.

I like to sort the list by the Last Used date. I’ll then review the oldest addresses listed and if I don’t recognize them then I’ll select one or more and remove them from the list too.

Dealing with spam or junk email in your Inbox is a waste of time. If you run a small business the time wasted identifying and deleting email can add up over weeks or months whether you are a one-person or multi-person team. Here are a couple of ways to reduce the amount of spam that you receive in your email Inbox.

First, make sure that your email provider’s email filtering feature is turned on. Almost every email provider has such a feature, but many of them are not very capable.

Next, you might consider setting up your own spam filtering application. For Mac users, I recommend SpamSieve. You can try it and if you find it effective then buy it for $30. It works with the most common email client applications including Mail, Entourage, Eudora and Thunderbird. This is a good solution for individuals.

If you own your own domain name and have a small workgroup then you might consider signing up for a email filtering service such as Big Mountain Hosting’s MailFoundry spam filtering service. In order to set this up you need to modify the MX (mail exchange) record within your DNS (domain name system) records. Specifically, you set your MX record to deliver all incoming email to the email filtering server. The server then scans all email messages and delivers legitimate email messages to your Inbox. All email messages that were identified as spam or contain a virus are put into a quarantine. You then receive one email that lists all quarantined messages. If a legitimate email was quarantined then you can  click a button to release the message from its quarantine and have it delivered to your Inbox.
I use Big Mountain’s spam filerting server and find it highly effective. Their plans start at $10/month for up to 5 users. They have tiered pricing for larger groups of users.

Here’s a list of features in Apple’s Mail application which I use regularly and people appreciate when I point them out.

1. Connection Doctor – Go to the Window menu and select Connection Doctor. A small separate window will appear. It quickly tests all of your incoming and outgoing connections to your mail servers. After a few seconds you should see green dots to the left of each item listed. If you see yellow or red dots then there’s a problem. If you’re having problem sending or receiving email then open Connection Doctor. It might give you some information that helps you to figure out where the problem is. If you see green dots next to all items and you still can’t send a particular email message then it’s time to look for typos on the recipient’s email address.

2. Send Again – To use this feature just click on a message in your Sent mail folder or any other mail folder, for that matter and then select Send Again from the Message menu. I use this feature when I want to send the same email message to different people but I want to address the message individually to each of them. This feature is also handy if I send a message and immediately remember that I forgot to include a piece of information. I’ll select the message I just sent from the Sent folder and add the missing information at the top of the message.

3. Remove Attachments – To use this feature select one or multiple messages and then select Remove Attachments from the Message menu. One can use this feature to quickly stip email messages of all attachments while preserving the message itself. This is useful for housekeeping purposes. Most people don’t need to hold onto the attachments for messages that they sent since that document is typically saved elsewhere on your hard drive.

4. QuickLook – This feature requires that you have Mac OS X version 10.5 or 10.6 installed. As you may know, QuickLook is feature of the Finder. Click on a file in the Finder and press the Space Bar key. OS X will show you a quick preview of the contents of the document. QuickLook doesn’t work with every type of document but it works with the most common types of files such as jpeg images, PDF files and files made with Word, Excel, Pages and Numbers. Apple built QuickLook into Mail. If you have an email message with an attachment look for the QuickLook button near the Attachments line of the email’s header information. It’s just a quick way to look at the attachment.

Do you access your email account from multiple computers? Have you added a smartphone into the mix as well? If so, you should be aware of IMAP. IMAP-enabled email accounts offers better email handling than old-fashioned POP email accounts.

Both POP and IMAP are communication methods used between email programs, like Apple’s Mail or Microsoft’s Entourage, and an email server. POP has been around for many many years. It works just fine but it’s model is out-dated. IMAP was developed around the realization that people increasingly want to check their mail from multiple computers (or cell phones or whatever). Thus, some or all of your email is stored on the server, not on just one computer. Then you can setup say, a home computer, a work computer and a smart phone to all access (view) that email (using IMAP). What you’ll see in your Inbox on each of those computers is the same. You’ll see the same list of messages on each computer plus you’ll see which messages are “new” or have the “replied to” mark next to them. If you delete a message from one computer, it’ll be deleted from the server then subsequently from each of the other computers when those computers next talk to the mail server.  In other words your Inbox stays synchronized across mulitple computers. This same type of synchronization can be setup for other mail folders like Drafts, Sent, Trash as well as saved messages. IMAP is very useful. Personally, I think everybody should be using IMAP, even if you’re only using one computer currently. If you’re interested in using IMAP you could contact your email provider. Not all email providers offer IMAP service. Or, if they do offer it they sometimes charge more since IMAP requires increased storage space on the server and increases the server’s workload.

There is a common myth that if one uses IMAP that email messages ONLY reside on the mail server. This is not true. Each computer will store it’s own local copy of email messages on its hard drive. This way, you can read or review email messages even if you don’t have Internet access such as while on a train or plane.

This recent article in TidBITS gives some more detail about IMAP and its features. You don’t have to read the entire article which covers other topics as well; just a few paragraphs about how IMAP works.
