Topic: How do I change the smtp port?

[Bill Prescott]

Help,

I am trying to use Mailwarden on a separate box. They tell me to change the smtp port on the mail server (SME 5.6) from 25  to 28 so it won't normally be connected to. How do I do this with SME 5.6?

Mail warden will catch the mail and after filtering it it will send it to the SME5.6 smtp port set in it.

Search the forum sir.

Okay, so i searched for change smtp port and it came up with a bunch of entries about port forwarding. I'm not sure this is what I want... I want to change the port to another one, not forward it to another one... Am I just searching for the wrong thing?

edit /etc/services

change
smtp    25
to
smtp 125 ( or whatever you want)

then

service smtpfront-qmail restart

It's my understanding that /etc/services is templated (on the version I run), if this is the case for 5.5 be sure to create a custom template.  See http://www.e-smith.org/custom for details.

Dean, thanks for the information.

I have tried changing the smtp port as directed here using a copy of services in templates-custom/etc to 2525, then expand the template. When I restart smtpfront-qmail and portscan it shows that port 25 has been closed but it does not open port 2525. I tried using portopen to open port 2525 but I have not been able to open any port using portopen.
I edited the smtp line to be 2525 instead of 25, am I missing something obvious here?
If I change back to 25 and restart smtpfront-qmail portscan shows that port 25 is again opened so I can tell that the changes are having an effect.
