avoiding problem with SMTP-Port 25

i found out, that some Internet-Provider disabled using port 25, because 25 is used for unAUTH-SMTP. so we have to switch to Port 587, which can be used for AUTH-SMTP. to do so, you have to add this line to
/etc/postfix/master.cf

587 inet n - - - - smtpd

Please don't forget to release the port at your Server-Firewall too.

 

I've moved this to the Tips & Tricks forum as well.

 

So, using that method, I can authenticate through my ISP's (Bellsouth) mail servers, allowing outbound mail traffic from my server?

If so... THANK YOU 100x over. I've been trying to be able to do that for the past month and a half!

How do I configure postfix to authenticate?

 

have a look there:

 

thank you so much!

Hopefully this will (finally) work now!

I'll try it out after I try the new ISPConfig 3 release :-D. Just downloaded Debian.

 

Then you have to wait a few months. It's far from being released.

 

The alpha was just released... ;-)

Now that I setup the demo server for it, I'm going to try out the postfix stuff on my real server

 

I know. But it's still a long way to the stable version...
