Adding SMTP Port on FreeBSD

[bray]

Hello,

I am trying to add an SMTP port to 587 since port 25 is blocked by many ISP's now. I have found this kb:

===================================
Choose any unused port and add it to /etc/services file, for example:

smtp_alt 25025/tcp # new SMTP port

Then make a copy of /etc/xinetd.d/smtp_psa to smtp_psa_alt and correct
service line within file:

service smtp_alt

Then restart xinetd and SMTP connections will be also accepted to 25025 port.
===================================

I have added the new port in the /etc/services file, but on FreeBSD, I see no /etc/xinetd.d/smtp_psa file? I presume this is for Red Hat instead of BSD. Does anyone know where this smtp_psa is located in FreeBSD?

These instructions are FreeBSD specific ..

Found this in my notes, this is how i set mine up.

I'm pretty sure these were from a thread on this forum someplace .. but i don't have referance to the original thread, i'm sure you could find it if you did a search ..

anyway here ya go ..
Duplicate the smtp lines in your /etc/services file..
ie..
existing...
smtp 25/tcp mail #Simple Mail Transfer
smtp 25/udp mail #Simple Mail Transfer

Add
smtp1 YOURPORT/tcp #Simple Mail Transfer
smtp1 YOURPORT/udp #Simple Mail Transfer


use the submission port :587 - used by sendmail as smtp, i use it on all my BSD boxes ..
_____________________________________
Next, update your /etc/inetd.conf file...
Look for the line that Plesk added, something like....
smtp stream tcp nowait root /usr/local/psa...(the rest of line)
Duplicate and add the entire line, and change the reference to smtp
to smtp1..ie...
smtp1 stream tcp nowait root /usr/local/psa...(the rest of line)

Restart inetd.. (send a sighup.. killall -1 inetd) as the root user.
