Re: mails not receiving

I just see logs like "timeout after DATA (455479 bytes) from viruswall3.irevna.com", it chould be a network related issue.

And you didn't post full log related to a SMTP session, it's hard to see what the root cause is.

Is it possible to contact postmaster of "irevna.com" to work together for this issue?

Re: mails not receiving

Hi

I got this message from symantec people who look our client mail
pipalresearch.com are are taking too long time scanning email attachments from you because they are using smtp filtering for your domain or they are using traffic shaping and your domain has a low confidence level causing delays in scanning. 421 and 450 means that the recipient domain is not accepting mails from you, not the other way around.

can we stop smtp filtering for irevna.com.

thanks
Philip

Re: mails not receiving

Great feedback, it helps.

Try to add "check_client_access" in postfix "smtpd_recipient_restrictions =":

smtpd_recipient_restrictions =
    ...
    check_client_access hash:/etc/postfix/client_access
    check_policy_service inet:127.0.0.1:10031

And create /etc/postfix/client_access with below content:

domain.ltd OK

Run postmap to create hash db, restart postfix to make it work:

# postmap hash:/etc/postfix/client_access
# /etc/init.d/postfix restart
