Entourage munging outbound SMTP addresses

[Tom Meunier]

Customer has an Entourage client (I'm waiting on the version number but I
suspect X). Set up as a POP3 client, sending SMTP against an Exchange 2003
server. Whenever it sends, it munges the recipient address in the SMTP
conversation's RCPT TO: line by prepending a 25/ to it. Below this message
are two conversations from Exchange SMTP logs that show the behavior.
Obviously the mail will bounce as 25/[email protected] isn't the real
address. The address book entries are fine, and the string 25/ is prepended
even on reply and reply-all messages.

I'll get more info, and have the customer rebuild the profile in a little
while, but I'm curious to see whether anyone's seen this behavior before,
and if not at least get it out there for archival purposes.
