[gentoo-user] Postfix Question

[gentoo-user] Postfix Question

[-- Attachment #1: Type: text/plain, Size: 3184 bytes --]

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.

Postfix:

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?

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.
pc130:~ admin$ telnet mail.ipr.edu 25

Connected to mail.ipr.edu.

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,
Jason

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 jason@ipr.edu then it tells me to try again later. If I  
try sending one to root@abulafia.ipr.edu 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.

Stroller.

Stroller,

Thanks for getting back to me on this. My original intent was to only send
mail from abulafia, not receive it from outside (of course it can be
delivered locally). Is it still necessary to have an MX record made for
abulafia? Maybe I'll go ahead and give that a try.

Joomla has always had a valid address as far as mail.ipr.edu is concerned,
but is from an address that doesn't exist locally on abulafia- matter? In my
experience this from address hasn't mattered. Unfortunately in joomla I
can't use an smtp server with ssl and a-plus requires it. If I could this
whole mess could be avioded- I'm not a mail man as it were.
