AOL: "This message could not be displayed..."

[idealizm]

When trying to view messages sent by my Listmail in any AOL account, it shows this error:

"This message could not be displayed. If possible, please ask the sender to resend. If the problem persists, please contact customer support."

I cannot find any trace of this error within these forums or Google, but it's definitely persistent among all of our AOL subscribers, and I am assuming it's something wrong AOL-compatibility-wise with how Listmail encapsulates the message?  Anyone else seeing this?

I am whitelisted with AOL, and have SenderID and SPF records setup successfully... I am baffled.

By the way, this problem only occurs in the web-based mail software.  The message appears fine within the AOL software itself.

I got off the phone with the idiot on AOL tech support... they said that Listmail is sending the message in an incompatible format, and AOL's webmail is not capable of viewing the message.

Hello,

I can run some tests with my own AOL account but I may need the exact email you are sending to be sure I can recreate the problem.

Can you submit your information and let me know which list and message it was that caused the problem?  Alternately, send me the Subject, Text and HTML of your message by email (dean@...) or via http://contact.listmailpro.com

Regards
