Hi. Im trying to install posfix on a Debian VPS. The Debian image they have, has sendmail built in. I stopped it and removed it. The problem is in my mail.log I get these errors: Code: postfix/smtp: connect to alt3.gmail-smtp-in.l.google.com[188.8.131.52]:25: Connection timed out warning: inet_protocols: IPv6 support is disabled: Address family not supported by protocol postfix/master: terminating on signal 15 IP is not blacklisted. Port 25 is not blocked. Any ideas ? edit: I think I found my problem. When i try to telnet somedomain.com 25 or telnet someIP 25 I get "connection timed out"
