Mail signatures change into attachments, why?

I recently switched my email accounts from POP to IMAP and all of a sudden, sometimes my signatures are getting converted into attachments after I send the message. The attachments get titles such as ATT00001.txt. I am using Mac Mail. It happens with my work account. I also have an iphone and use mobile me to synch it with three other intel macs. But this happens without any involvement of AT&T and my iPhone.

iMac intel, Mac OS X (10.5.6), iphone, macbook Pro

I was having this same problem today, and I figured out what is happening.

When you send an attachment to Microsoft Outlook, the way that it handles rich text causes issues when you put the attachment icon in the body of the email.

I noticed that it only happens with non-image files. So .doc, .docx, etc. It doesn't cause problems when attaching .jpg or .pdf.

Any text that is located AFTER the icon you've attached is converted to ATT00001.txt when opened in Outlook. (and maybe other programs, I'm not sure)

The way to fix this is either:
1) drag or place the icon to the very end of the email, (including after the signature) OR
2) Go to the "Edit->Attachment" menu and check "Insert attachments at end of message."

Note, with option 2, you can set it as your default, thus not worrying about it.

The only issue is that when sending messages to other mac users, you can't have attachment icons show up in the middle of the email body.
