Hi, I have a postfix mail server over which I have deployed a custom content filter written in java.
Now I introduced amavisd (containing clamav and spamassassin) as content filter such that the mail is passing in following manner: ===>mail from outside ===> Postfix ====> amavisd ===> custom content filter I referred the link(http://wiki.centos.org/HowTos/Amavisd) to setup amavisd(containing clamav and spamassassin) Here my setup is running ok when amavisd is bypassed and mail is directly being sent to custom content filter but I receive following error logs as soon as I start passing my mails via amavisd: Apr 7 11:36:14 ip-10-194-99-63 postfix/smtpd[3585]: connect from mail-pw0-f48.google.com[209.85.160.48] Apr 7 11:36:14 ip-10-194-99-63 postfix/smtpd[3585]: BABCC100191: client=mail-pw0-f48.google.com[209.85.160.48] Apr 7 11:36:14 ip-10-194-99-63 postfix/cleanup[3593]: BABCC100191: message-id=<x2h6c32076e1004070836p20a8cdabz104ac2c1d55a2...@mail.gmail.com> Apr 7 11:36:15 ip-10-194-99-63 postfix/qmgr[3583]: BABCC100191: from=<ashiish.sha...@gmail.com>, size=1966, nrcpt=1 (queue active) Apr 7 11:36:45 ip-10-194-99-63 postfix/smtpd[3585]: disconnect from mail-pw0-f48.google.com[209.85.160.48] Apr 7 11:36:54 ip-10-194-99-63 amavis[3264]: (03264-02) (!)rw_loop: leaving rw loop, no progress, last event (select) 34.987 s ago Apr 7 11:36:54 ip-10-194-99-63 amavis[3264]: (03264-02) (!)SEND via SMTP: <> -> <ashiish.sha...@gmail.com>, 451 4.5.0 From MTA([10.194.99.63]:10030) during fwd-connect (Negative greeting: at (eval 57) line 596, <GEN18> line 162.): id=03264-02 Apr 7 11:36:54 ip-10-194-99-63 amavis[3264]: (03264-02) (!!)TROUBLE in check_mail: delivery-notification FAILED: temporarily unable to send DSN to <ashiish.sha...@gmail.com>: 451 4.5.0 From MTA([10.194.99.63]:10030) during fwd-connect (Negative greeting: at (eval 57) line 596, <GEN18> line 162.): id=03264-02 at /usr/sbin/amavisd line 11359, <GEN18> line 162.
