Any errors in your mail log?

Also make sure that your server isn't blacklisted: http://mxtoolbox.com/blacklists.aspx

Is it possible to set up Postfix to send e-mails to an outside address such as a gmail.com address from a .local address?

It seems that port 25 is either blocked by your ISP or it's closed by you firewall. Where is this server, at you house or in datacenter?

[dongsky]

..Is in the datacenter ....so that means only in the ISP would be the problem?.(regarding firewall.)..

Did you check if your server is blacklisted?

When i change it to my google account..here's the log files.:


Sep 6 17:32:03 localhost postfix/qmgr[2711]: 916A51C8F63: to=<loremuelgadrinab@gmail.com>, relay=none, delay=91, delays=0.25/91/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to alt4.gmail-smtp-in.l.google.com[209.85.229.27]: Connection timed out)
