> We need to see all the smtpd logging. Noel, so do I append "-v" or "-D" on the smtpd line in master.cf ? Or are you referring to "strace -p postfix_process_pid" ?
> provide complete NON VERBOSE postfix logging So do I remove "-v" & use "-D" in master.cf, restart postfix & send test emails ? Jerry suggested putting back the vanilla main.cf & master.cf : I've made backup copies of those right after doing postfix install ("rpm -i rpmfile") so I'll try that first thing tomorrow morning. > It seems then that this is a routing issue, not a Postfix issue. Probably not a network routing issue as I could send mails out from this Postfix server, just that I can't get the incoming mails. This box is an Intranet server too & that part works fine, so not a network routing case; maybe 'mail routing' if there is. > I'm a little confused about your logs since it seems you've got two Postfix > instances running "ps -ef | grep -i postfix" only showed one process. sendmail is also not running on this box. If I do "/etc/init.d/postfix stop", "telnet localhost 25" would not respond, so doesn't look like there's another MTA process =================================================== # postconf -n alias_database = hash:/etc/postfix/aliases alias_maps = hash:/etc/postfix/aliases bounce_size_limit = 65536 command_directory = /usr/sbin config_directory = /etc/postfix daemon_directory = /usr/libexec/postfix data_directory = /var/lib/postfix debug_peer_level = 2 debug_peer_list = mds.com.sg default_privs = nobody header_size_limit = 32768 html_directory = /usr/share/doc/postfix-2.5.6-documentation/html inet_interfaces = all mail_owner = postfix mail_spool_directory = /pop3/spool/mail mailq_path = /usr/bin/mailq.postfix manpage_directory = /usr/share/man message_size_limit = 51200000 mydomain = myportaltech.com myhostname = hostname mynetworks = 172.18.x.y/24, 127.0.0.0/8, 202.6.163.0/24 myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /pop3/spool/postfix readme_directory = /usr/share/doc/postfix-2.5.6-documentation/readme relay_domains = myportaltech.com sample_directory = /etc/postfix sendmail_path = /usr/sbin/sendmail.postfix setgid_group = postdrop smtpd_banner = $myhostname ESMTP POSTFIX smtpd_recipient_limit = 500 smtpd_recipient_restrictions = reject_invalid_hostname, reject_unauth_pipelining, permit_mynetworks, permit_sasl_authenticated, reject_unauth_destination, check_client_access hash:/etc/postfix/rbl_override, reject_rbl_client multi.uribl.com, reject_rbl_client dsn.rfc-ignorant.org, reject_rbl_client dul.dnsbl.sorbs.net, reject_rbl_client list.dsbl.org, reject_rbl_client sbl-xbl.spamhaus.org, reject_rbl_client bl.spamcop.net, reject_rbl_client dnsbl.sorbs.net, reject_rbl_client cbl.abuseat.org, reject_rbl_client ix.dnsbl.manitu.net, reject_rbl_client combined.rbl.msrbl.net, reject_rbl_client rabl.nuclearelephant.com, permit smtpd_sasl_auth_enable = yes smtpd_sasl_security_options = noanonymous smtpd_timeout = 360 soft_bounce = no unknown_local_recipient_reject_code = 550 =================================================== # ./postfinger.sh --nowarn postfinger - postfix configuration on Thu Feb 17 10:12:16 SGT 2011 version: 1.30 --System Parameters-- mail_version = 2.5.6 hostname = xxxxxxxx uname = Linux xxxxxxxx 2.6.12.6-xen0 #1 Tue Jan 31 16:03:21 GMT 2006 i686 i686 i386 GNU/Linux --Packaging information-- looks like this postfix comes from RPM package: postfix-2.5.6-1.rhel4 --main.cf non-default parameters-- alias_database = hash:/etc/postfix/aliases alias_maps = hash:/etc/postfix/aliases html_directory = /usr/share/doc/postfix-2.5.6-documentation/html mailq_path = /usr/bin/mailq.postfix mail_spool_directory = /pop3/spool/mail manpage_directory = /usr/share/man mydomain = myportaltech.com myhostname = smtp.myportaltech.com myorigin = $mydomain newaliases_path = /usr/bin/newaliases.postfix queue_directory = /pop3/spool/postfix readme_directory = /usr/share/doc/postfix-2.5.6-documentation/readme sendmail_path = /usr/sbin/sendmail.postfix smtpd_sasl_auth_enable = yes --master.cf-- smtp inet n - n - - smtpd pickup fifo n - n 60 1 pickup cleanup unix n - n - 0 cleanup qmgr fifo n - n 300 1 qmgr tlsmgr unix - - n 1000? 1 tlsmgr rewrite unix - - n - - trivial-rewrite bounce unix - - n - 0 bounce defer unix - - n - 0 bounce trace unix - - n - 0 bounce verify unix - - n - 1 verify flush unix n - n 1000? 0 flush proxymap unix - - n - - proxymap proxywrite unix - - n - 1 proxymap smtp unix - - n - - smtp relay unix - - n - - smtp -o smtp_fallback_relay= showq unix n - n - - showq error unix - - n - - error retry unix - - n - - error discard unix - - n - - discard local unix - n n - - local virtual unix - n n - - virtual lmtp unix - - n - - lmtp anvil unix - - n - 1 anvil scache unix - - n - 1 scache -- end of postfinger output --
