I have a postfix 2.6.6 installed on a centOS 6.8, I would like to use it to send notifications of nagios, sending email in local work fine but I don't manage to send them to my email address through my domain.

The port 25 is open in my local machine and now I change the relayhost to put the smtp server of my ISP Code: relayhost = smtp.vsnl.net And there is the output of tail -f /var/log/maillog Code: May 8 10:36:21 AM004 postfix/error[18595]: 8D32243C8A: to=<nagios@fbr***.com>, relay=none, delay=0.01, delays=0.01/0/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to smtp.vsnl.com[203.13.40.33]:25: Connection timed out) Do you know where can come the error. Thanks
Thanks you for the link but that doesn't solve my issue have you others suggestions please. The ping is ok and there is a result of a traceroute Code: [root@AM004 ~]# traceroute -n -T -p 25 203.13.40.39 traceroute to 203.13.40.39 (203.13.40.39), 30 hops max, 60 byte packets 1 * * * 2 * * * 3 * * * 4 * * * 5 * * * 6 * * * 7 * * * 8 * * * 9 * * * 10 * * * 11 * * * 12 * * * 13 * * * 14 * * * 15 * * * 16 * * * 17 * * * 18 * * * 19 * * * 20 * * * 21 * * * 22 * * * 23 * * * 24 * * * 25 * * * 26 * * * 27 * * * 28 * * * 29 * * * 30 * * *
You also have to remove the domain that you want use to send email from your destination. I think this $mydomain is what you want to use to send emails, so try removing that from mydestination.
OK I remove $mydomain in my destination but I still have the message error Code: May 9 13:20:33 AM004 postfix/error[21297]: B600B43BD6: to=<[email protected]>, relay=none, delay=0.04, delays=0.03/0/0/0, dsn=4.4.1, status=deferred (delivery temporarily suspended: connect to smtp.vsnl.com[203.13.40.33]:25: Connection timed out) I maybe have to reinstall postfix, I'm desperate to trying to make it work
Do this from the postfix server. telnet smtp.vsnl.com 25 Do you get the SMTP header? If not your not getting to the relay host from that machine which is what it looks like is happening.
