Running SMTP on multiple ports (postfix)

[alex916]

Great! Now it's perfect and i can send email using m isp-config server also if another isp block port 25.

Thanks

I'm having the same problem and getting the same error message, but the fix does not work for me. Any ideas?

[gwa7]

This is what worked for me. I had to make both lines match:

smtp inet n - n - - smtpd
587 inet n - n - - smtpd

(I actually used a different port number than 587)

One more thing for Evolution users:
If you change the default smtp port, add the port to the end of your mail server like this: mail.yourserver.com:587

thanks to you guys i have the company email working..

as they are so tight on security. i cant use port 25 properly over the vpn so i now have 587 doing the same job.

Keep up the good work guys.

As I stated earlier, these settings worked for me:

smtp inet n - n - - smtpd
587 inet n - n - - smtpd

TLS encryption works on the new port 587. It also works without encryption on this port.
SSL encryption works on port 25.
However, when I try to send an email to my server with SSL on port 587, it just sits in the outbox. Any ideas on what I need to change to make this work?

I appreciate your help and thanks again for ISPconfig!

What's in /etc/postfix/master.cf? Any errors in your mail log?

Thanks for your quick reply. I am actually using port 2525 instead of 587.

Hi All,

it worked for me perfectly, however i want to use my ispconfig server as alternative smtp server for domains that are not hosted on the ispconfig server. I add the domain and create the desired users that should be able to use the ispconfig alternative smtp server, everything works perfect, only 1 thing do not - sending mails from that domain to itself. The ispconfig handles these mails internal. I have set "External Mailserver" for that domain but that didnt helped at all. I also deleted the domain from /etc/postfix/local-host-names but after running /root/ispconfig/php/bin/php /root/ispconfig/scripts/writeconf.php this domain is automaticaly added in /etc/postfix/local-host-names. What can i do to achieve my target?
N/B I hope there will be an "ISPconfig way" doing this because i want ppl that do nnot have access to the server but only to ispconfig admin interface to be able to add domains and users which will be able to use the alternative SMTP port...

Thanks in advance!!!!!

Did you do this only for the main FQDN (e.g. www.example.com), or also for the Co-Domains? Each Co-Domain has its own Options tab where you can select "External Mailserver".

only for FQDN, i have no subdomains for the test domain... but postfix tries to deliver locally...
