what exactly do you think get better if you send the same
message with a changed subject to the same mailing-list two
days later?

Hi all, new to the group. Have recently setup POSTFIX as an SMTP relay front 
end to an Exchange 2007 backend. Have
encountered the following issue:

I'm using POSTFIX as an SMTP fronted relay to an Exchange
<http://www.tek-tips.com/viewthread.cfm?qid=1663396&page=1> 2007 backend. The 
default size for attachments in
POSTFIX is 10 MB. I've set that in the configuration file to be 20 MB. When I 
look at postconf -n it verifies that
the limit is set to 20 MB, (message_size_limit = 20480000). I've stopped and 
restarted the postfix service, but
messages are still bounced back to my Exchange server 
<http://www.tek-tips.com/viewthread.cfm?qid=1663396&page=1>
as undeliverable if they exceed 10 MB in size.) The bounce-back message users 
receive lists the Debian Linux /
Postfix server as the server bouncing it back for exceeding size. Is there 
somewhere else this needs to be set?

The error message I get from exchange is:

This message exceeds the maximum message size allowed. Microsoft Exchange will 
not try to redeliver this message
for you. Please make the message smaller -- by removing attachments, for 
example -- and try sending it again, or
provide the following diagnostic text to your system administrator.

The following organization rejected your message: 
{POSTFIX_SERVER.OUR_DOMAIN.com.
