Postfix help

  • Hi all,
    Having loads of problems with clients complaining about not receiving email from certain domains.


    Seems that loads of servers are badly configured and this then causes problems with mine.


    Here is an example of a good email but gets rejected because their reverse dns is bad.


    Code
    1. cat mail.log | grep [email protected] 22 17:22:22 sosaria postfix/smtp[12946]: 7B3A4195B081: to=<[email protected]>, relay=mail.sanituboexpo.com[213.9.234.90]:25, delay=3.1, delays=2.3/0.01/0.43/0.4, dsn=2.0.0, status=sent (250 2.0.0 Ok: queued as 0939582CA3)Jan 23 16:46:07 sosaria postfix/policyd-weight[2691]: weighted check: NOT_IN_SBL_XBL_SPAMHAUS=-1.5 NOT_IN_SPAMCOP=-1.5 BL_NJABL=SKIP(-1.5) CL_IP_EQ_HELO_IP=-2 CL_SEEMS_DIALUP=3.75 HELO_SEEMS_DIALUP=4.5 (check from: .sanituboexpo. - helo: .clientes1.cherrytel. - helo-domain: .cherrytel.)

    I've tried commenting some of the HELO stuff to try and get postfix to accept more of these trouble domains. Can anyone lend a hand to have more relaxed rules?


    Here is my /etc/postfix/main.cf
