Hello List, I have an installtion using bitdefender as a virus scanner using the content_filter option. bitdefender's smtp daemon listens on port 10025, in main.cf therefore this is defined:
content_filter = smtp:[127.0.0.1]:10025 In master.cf a second instance of smtpd is defined, listening on port 10026: 127.0.0.1:10026 inet n - n - 10 smtpd -o content_filter= -o smtp_send_xforward_command=yes When smtp tries to send the mail to bitdefender for scanning, this happens: Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 220 linuxgw.myown.net ESMTP Postfix Jul 17 11:42:55 linuxgw postfix/smtp[20313]: warning: host 127.0.0.1[127.0.0.1] greeted me with my own hostname linuxgw.myown.net Jul 17 11:42:55 linuxgw postfix/smtp[20313]: > 127.0.0.1[127.0.0.1]: EHLO linuxgw.myown.net Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 250-linuxgw.myown.net Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 250-PIPELINING Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 250-SIZE 502400000 Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 250-VRFY Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 250-ETRN Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 250-XVERP Jul 17 11:42:55 linuxgw postfix/smtp[20313]: < 127.0.0.1[127.0.0.1]: 250 8BITMIME Jul 17 11:42:55 linuxgw postfix/smtp[20313]: warning: host 127.0.0.1[127.0.0.1] replied to HELO/EHLO with my own hostname linuxgw.myown.net Jul 17 11:42:55 linuxgw postfix/smtp[20313]: connect to subsystem private/defer Jul 17 11:42:55 linuxgw postfix/smtp[20313]: send attr nrequest = 0 Jul 17 11:42:55 linuxgw postfix/smtp[20313]: send attr flags = 0 Jul 17 11:42:55 linuxgw postfix/smtp[20313]: send attr queue_id = 2859B35121 Jul 17 11:42:55 linuxgw postfix/smtp[20313]: send attr original_recipient = tz@localhost Jul 17 11:42:55 linuxgw postfix/smtp[20313]: send attr recipient = t...@localhost.myown.net Jul 17 11:42:55 linuxgw postfix/smtp[20313]: send attr reason = mail for 127.0.0.1:10025 loops back to myself main.cf contains mydestination = $myhostname, localhost.$mydomain,$mydomain I think, the bitdefender uses a correct answer for the EHLO, there is no way (i know of) to change the 250 answer of bitdefender. After a dozen hours of research any hint would be appreciated. Regards, Thomas Zehbe
