ok I haven't really changed anything but some more time has passed since my last post and now it seems like *google* doesn't appear in the logs anymore. on the other hand I keep seeing connection timed out like this: Jul 13 07:25:09 domU-12-31-39-00-5D-07 postfix/smtp: connect to mail.mydomain.com[75.101.163.xx]: Connection timed out (port 25) and im still seeing example.com Jul 13 07:27:06 domU-12-31-39-00-5D-07 postfix/smtp: ABB62F432E: to=<[email protected]>, relay=none, delay=330408, delays=330378/0.03/30/0, dsn=4.4.1, status=deferred (connect to example.com[22.214.171.124]: Connection timed out) Jul 13 07:27:06 domU-12-31-39-00-5D-07 postfix/smtp: connect to example.com[126.96.36.199]: Connection timed out (port 25) and im still seeing Jul 13 07:22:46 domU-12-31-39-00-5D-07 imapd: chdir mydomain.com/sales/: No such file or directory and it looks like something is queued somewhere Jul 13 07:26:36 domU-12-31-39-00-5D-07 postfix/qmgr: ABB62F432E: from=<[email protected]>, size=1050, nrcpt=1 (queue active) also, if i go to http://mail.mydomain.com, on one computer i get a 404 "server not found error" and from another computer i see the "Apache 2 Test Page". somebody asked me this "is your amavis giving back the mail not on localhost and the port is just bound to localhost?" and said to check /etc/postfix/master.cf and amavisd.conf but I didn't really understand what I'm supposed to change =/ and somebody else said "Sounds like a firewall/port 25 block to me"... I did follow this guide http://www.crypt.gen.nz/selinux/disable_selinux.html and disabled selinux like you said in the beginning of the guide. [[email protected] selinux]# cat /selinux/enforce 0[[email protected] selinux]# here is the output of "iptables -L": also when i "telnet localhost 25" it works fine, but if i do it remotely, i get connection refused =/ finally, i've sent a new email from gmail and another provider to [email protected] and this time it took 50 minutes to bounce back.
