TRUNCATED MESSAGES

Are these truncated messages primarily messages that were forwarded and either the original message or any text included by the sender with the forwarded message was composed in HTML?

With such a message open, at the menu bar go to View > Message and select Plain Text Alternative. If the received or forwarded message was not composed in HTML, the Plain Text Alternative option will not be available.

This should resolve the viewing problem on your end but I'm unsure where the problem lies. I see the same primarily with messages forwarded by an AOL user.

AGAIN, this Mail program fails to operate properly. Why do I have to go through these extra steps when Entourage works?

I desperately wish Apple would make Mail work properly.

Thanks for this tip! I have also found that if I quit mail and reopen, it will usually display the entire message in question. As the OP said, this only occurs with messages forwarded from AOL users.

I thought AOL had moved away from their proprietary client??? Still, Mail shoul dbe able to render the message properly...

AOL hasn't moved away from their proprietary client but AOL users have the ability to access their email accounts with an email client such as the Mail.app by creating the account as an IMAP type account.

AOL software has always been problematic in some areas - primarily with attachments, sending and receiving.

Is there anyway to have Mail.app automatically display messages from aol.com domain in Plain Text Alternative?

You can do so via the Terminal but for all received messages. You can't specify this for messages received from a particular domain only.
