Email Attachment Tests
You can use the links on this page to test how your email service or application deals with different kinds of file attachments sent to you using different formats from a Macintosh email program. Please see "Email Attachment Formats Explained" in TidBITS 515 and "Email Attachments: Who Does What" in TidBITS 516 for details on each of these formats and how different email programs support them. Want to see if you can receive an inline GIF encoded with Base64 via your Lotus Notes account at work? The links below will tell you.
How The Links Work -- The links on this page use mailto: URLS to create a new blank message with a specific subject in your email program. You can then send this message as you would any other. Some email programs don't support specifying a subject in a mailto: URL. If that's true for your email program, you'll need to copy the entire URL for the test you wish to perform to the clipboard and paste it into the body of the message the link created. Then manually cut the subject specified in the URL and paste it into the subject field of your email program. This system checks for exact matches in the subject lines to avoid loops and reduce the impact of spammers, so be careful when creating your requests manually.
How The System Works -- Messages you send based on these links are received by a copy of Eudora running on a Power Mac 7100. It checks mail every 10 minutes or so, then uses a combination of stationery and filters to send you the appropriate reply. Barring network problems, you should receive a reply within about 20 minutes, if not sooner. Please use this service sparingly and only for serious testing, since it's not intended to support extremely high loads.
