I followed that how-to : http://www.howtoforge.com/virtual-users-domains-postfix-courier-mysql-squirrelmail-ubuntu8.04 I can login in the webmail and send e-mails to address like gmail, hotmail, yahoo, etc. But when i try the other way, to send form gmail to my server for example, the message is not delyvered. I just can see this in the logs: Aug 12 11:31:06 servermail pop3d-ssl: LOGIN, [email protected], ip=[::ffff:200.129.167.34], port=[49394] Aug 12 11:31:06 servermail pop3d-ssl: LOGOUT, [email protected], ip=[::ffff:200.129.167.34], port=[49394], top=0, retr=0, rcvd=12, sent=39, time=0 Aug 12 15:35:10 servermail postfix/anvil[5784]: statistics: max connection rate 1/60s for (smtp:200.189.174.197) at Aug 12 11:30:58 Aug 12 15:35:10 servermail postfix/anvil[5784]: statistics: max connection count 1 for (smtp:200.189.174.197) at Aug 12 11:30:58 Aug 12 15:35:10 servermail postfix/anvil[5784]: statistics: max cache size 1 at Aug 12 11:30:58 Aug 12 15:37:17 servermail postfix/smtpd[5816]: connect from rv-out-0506.google.com[209.85.198.237] Aug 12 15:37:17 servermail postfix/smtpd[5816]: lost connection after CONNECT from rv-out-0506.google.com[209.85.198.237] Aug 12 15:37:17 servermail postfix/smtpd[5816]: disconnect from rv-out-0506.google.com[209.85.198.237] Why does this happen?
