I'm completely confused on this one:
I have someone outside our domain who cannot send an email IN to our domain UNLESS he is replying to an email that was sent FROM our domain. If he starts a new email (vs a reply) he will receive a bounce-back (Note: ##.###.###.## is the external IP addy of my Exchange server):
"##.###.###.## failed after I sent the message.
Remote host said: 552 4.3.1 Message size exceeds fixed maximum message size"
This will occur even if the email is only a few KB!! As far as I know, this is an isolated case but I'm going to guess that other people have encountered the same problem but I've just never been notified...
I am STUMPED!!!! Any help & guidance would be greatly appreciated! Thanks in advance!
