Need to relay to ISP through port 587

Hello,


We need to set up relay through ISP smart host, but use the 587 port.


What Postfix file needs to be changed for that?


Regards


Kostas

Virtually all Postfix configuration is handled through /etc/postfix/main.cf


Specifically, the setting you're looking for is relayhost


relayhost = mail.yourisp.net:587

Do I need to regenerate sasl_maps?


I can't imagine sasl_maps has any connection/bearing on relayhost


What to do with Server Admin GUI? Do I set it there, too?


For the most part all Server Admin does is view the current config file (in this case main.cf) and writes certain parameters (ones it knows about), so in this case when you open Server Admin and look at the mail settings for 'relay all messages through:' it just reads the relayhost setting from main.cf. If you change the setting in Server Admin, it just writes the value back to main.cf... in other words, Server Admin is just a GUI front end to the same file.

Therefore I'd expect whatever value you set manually in main.cf to appear when you look at the settings in Server Admin (and vice versa)
