Note though that outbound port 25 is blocked, but my smarthost listens on the submission port as well if auth is used. So my relayhost line says: relayhost=my.smarthost.com:587 On my relayhost maillog I can see the connection appears, but mails are bounced with: 530 5.7.0Authentication required (in reply to MAIL FROM command) $ cat /etc/postfix/relay_password your.smarthost.com yourusername:yourpassword I have tried my.smarthost.comusername:password and [my.smarthost.com]:587username:password and my.smarthost.com:587username:password With various entries in main.cf to co-incide with these... (and remembering to run postmap each time). $ postmap /etc/postfix/relay_password $ service postfix reload You can check out the commented option in the man pages or http://www.postfix.org/postconf.5.html if you're interested later/have some spare time/if it doesn't work ;-) The line I get in the logs on my smarthost is: Jan 11 18:31:35 gate sendmail[17441]: STARTTLS=server, relay=188.29.xxx.xxx.threembb.co.uk [188.29.xxx.xxx], version=TLSv1/SSLv3, verify=NO, cipher=DHE-RSA-AES256-SHA, bits=256/256 The mail just bounces back to the sender, nothing else on the smarthost logs. ___ CentOS mailing list CentOS@centos.org http://lists.centos.org/mailman/listinfo/centos

My smarthost doesn't use SASL, just STARTTLS - I have tried all those options to no avail.. Perhaps some combination of options might work... but which...

[CentOS] Centos 6.2 Postfix - forward through SMTP smarthost with SMTP-AUTH
Hi All, I have set up three servers in a development environment. Via CR they're updated to Centos 6.2 It appears that these servers have postfix installed on them by default, which unfortunately I'm not very well acquainted with. All I want is a quick and dirty way to enable these hosts to send email through my own SMTP host. My (sendmail) SMTP host uses SMTP AUTH on a non-standard port and my dev (virtual env) runs off my laptop, so a dynamic IP. Does anyone have a quick and dirty configuration for setting up postfix to forward all remote mail through my smarthost? I'm guessing that I can put the hostname, the port, and the username and password somewhere in the postfix configuration and it will just work...
