Hi all,
Hope you can help me with this.
I did a fresh install of Centos 5 with postfix-2.3.3-2 from RPMs,
Spamassassin, Amavisd-new and Clamav. everything is going very good
until I send messages to mail.osterlingfirm.com
<http://mail.osterlingfirm.com> if the message is tiny, there are no
problems anything bigger than 100k will receive the following:
Sep 4 16:34:11 mail postfix/smtp[22137]: send attr original_recipient =
[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>
Sep 4 16:34:11 mail postfix/smtp[22137]: send attr recipient =
[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>
Sep 4 16:34:11 mail postfix/smtp[22137]: send attr dsn_orig_rcpt =
rfc822;[EMAIL PROTECTED] <mailto:[EMAIL PROTECTED]>
Sep 4 16:34:11 mail postfix/smtp[22137]: send attr reason =
conversation with mail.osterlingfirm.com
<http://mail.osterlingfirm.com>[200.31.124.213 <http://200.31.124.213>]
timed out while sending message body
This is the reason why I tweaked (and probably exagerated) the smtp_data
parameters.
They have a M$ MTA and as I can read, a Symantec appliance as mailrelay:
220 osterling08.osterlingfirm.com <http://osterling08.osterlingfirm.com>
ESMTP Symantec Mail Security

Please post complete NON VERBOSE logging of a failed
transaction. If someone needs verbose logging, they will ask
for it.
It may be helpful also to post a packet capture of a failed
session.

Are you able to send large mail to other sites successfully?
If this happens with all sites you may have an MTU problem.
Broken MTU is a networking problem, not a postfix problem -
google for more info.
And for a fresh install, why use musty old software? Current
postfix is 2.5.5 - but this is probably not related to your
problem. Hopefully you're not using years-old versions of
SpamAssassin, amavisd-new, and clamav also.
