Hi there,
Sorry to be so long replying - I've been busy with work & haven't
been reading the list. In case you're still having problems - and for
the benefit of teh Googles - it looks to me like mail.ipr.edu may be
doing clever greylisting & stuff.
If I telnet in and - giving a legitimate from: address - try sending
a message to [EMAIL PROTECTED] then it tells me to try again later. If I
try sending one to [EMAIL PROTECTED] I get user unknown (in fact,
I think there is no MX record for abulafia.ipr.edu).
I don't know for sure whether things have changed at mail.ipr.edu in
the last week, but maybe it's rejecting the mail because the from:
address is invalid. I would try changing the from: address set by
Joomba.

Thanks for your response. Here is the output of my telnet test. I
guess I'm really not sure what to make of it. The bolded text is of
some concern to me.

Thanks again. I'm not necessarily looking for someone to give me
the answer, as it were, but if I could get some help looking in the
right direction I would be very appreciative.
Best to you,

It's kinda difficult to help with this, without knowing what the A-
Plus server is seeing.
An unsanitised copy of the bounce message would probably show the
problem.
Does it definitely show the correct email address of a user for
which A-Plus has a mailbox?
Can you reproduce the problem telnetting to the A-Plus MX server on
port 25?

I guess I'll dip my toes in here and admit that I can't figure
this out.
Synopsis: I've setup Postfix to be a mail out only smtp server. I
just want it for our Joomla based web pages and our helpdesk to be
able to mail to users from the local server. The problem is this:
I can mail to any domain (gmail, hotmail, yahoo, etc) without
problem, but I can't receive mail directly through our A-plus
based mail (the worst!). What happens is that A-plus' server
rejects the user as unkown even though I know it is correct. What
really gets my goat is that after that message is returned to my
server it is then delivered to the A-plus server and thusly shows
up in my webmail and email client. Below are my configs.
