smtpd on port 26

[Anonymous]

Hi everybody

i have one more problem :-)

i changed the port that smtpd listens to 26

when i nmap my domain it appears as opened

when i send mails through my server's squirrelmail it goes ok

but i still can't receive mails
as i have a dynamic ip i use no-ip to redirect my real ip....i believe that my problem is on that point

I have read in the net that i have to make some tests with something like MX. Could anybody explain what is MX?

And does anybody knwo how to receive mails in my domain? I feel that I am close to an answer, but now is the difficult part.. :-)

thanks again

Personally, I would choose a port over 1024. Everything between 0-1024 is privileged, and it's just good practive to not use anything in that range. I am assuming that you did that because your ISP is blocking smtp? If so, you might need to set up some kind of port forwarding. Since I've never had this issue (my ISP doesn't seem to care if I run a home email server), I haven't investigated a solution.

Don't forget your log files, they're there for a reason.

MX is an abbreviation for Mail eXchanger. It's used in DNS to designate the server that will receive email bound for your domain. If your DNS setup does not have an MX, you'll never receive email because other servers don't know where to send the email. You might want to do a little research on Dynamic DNS, such as from dyndns.org.
