exchange 2003 delivery failures
i have a unique situation. i have a user that is unable to send a particualr email with certain conditions. the email is a small excel attachment. that delivers interally perfectly fine, but fails externally. actually it hangs in queue and eventually fails.
the user can email to individuals all day long but when you add mutiple people (3) to the recipient list with the attachment it never leaves the queue.
4.7.7 delay error connection dropped by host.
funny thing is that one of the domains this user sends to doesn't have any filtering enabled.
it seems to be a failure on the sending server not the receiving server since it is for mutiple domains.
any help would be great.

Are there details on the NDR? Have you checked the properties on the SMTP relay connector, any limits?
Do you deliver email directly, or via a smart host?
What is between Exchange and the internet? A firewall? If so, what is it?

directly. nothing installed that is new. same firewall as always no changes. (that i am aware of) it is a cisco appliance.

4.7.7 delay.. then fails.
in the queue it specifies that the remote dropped the connection.
10 limits and no changes on the connector
the email in question is under 55k

i read about that... is it per transmission? or based on address? or based on sender?
No, it is a transport thing - it just gets in the way.
It is so notorious it even has an article on the MSKB: http://support.microsoft.com/kb/320027
