Can't receive mail after entering new IP

Have you changed your DNS MX records to point to the new IP? Go to
http://www.mxtoolbox.com/ and put in your domain and click on Lookup.
If the host(s) that come up aren't your new IP(s) then update your DNS.


If they are correct, what happens if you try to connect to the
hostname(s) from outside your office with a telnet session? Start a
command prompt then type:


telnet mail.example.com 25


substitute your hostname (from the lookup above) for mail.example.com.
You should receive back a line that starts (mail.example.com will be
your hostname):


220 mail.example.com ESMTP MDaemon 10...


If you can't do that, post the domain back here and someone can test it.
  You could also try the SMTP Test on the lookup results page and see
what results it give you.


Post back your results and further questions if you need more help.

I found the problem. It's a common one, namely port 25 blocking. My ISP doesn't allow traffic on port 25 so I guess I'll have to change ports for SMTP and try to find a (cheap) mail relay service.

Thank you anyway,
