Dear Mr. Kruppa
I have some futher querries :-
1. Is this server your mail server for your domain. meaning does the
mail exchange record for your domain point to this server or some
other server.
In case it it pointing to some other server say Google mail server or
any other hosting provider. Then I would suggest you install something
like fetch mail to get mails fro your mail server to your postfix
server.
I believe that is what Frank Elsner was so nice to test from
"outside"
# host -t mx pukruppa.de
pukruppa.de mail is handled by 10 mail.pukruppa.de.
# telnet mail.pukruppa.de 25
Trying 217.92.171.227...
telnet: connect to address 217.92.171.227: Connection timed out
2. can you telnet your postfix servers external ip on port 25 from
outside your network.
If no, then that is the issue.
Yes, but what can I do? port 25 seems to point to my
Fedora box.
