Postfix don't receive emails

[webcitron]

Hi.
Im a new in this forum so you welcome for your patience )
I set up my home serwer with http://www.howtoforge.com/perfect-se...10-ispconfig-3 howto. All works fine for me except one think - Postfix don't receive emails from any external servers (sending is ok).
I read all threads on this forum and find out to I must configure DNS records. I don't know what is correct way to do this.
It's possible that is not a DNS reason. Can you help me to finr reason and fix it ?
I don't paste any configs etc, please tell what you want and I paste it here

Please check if the MX record of your domain points to your server. You can check that with

dig mx yourdomain.com

[webcitron]

dig mx [domain] returnet that:

administrator@lemon:~$ dig mx hepson.pl

It's right ?

Does hepson.pl point to your server? You can check that with

dig hepson.pl

[webcitron]

Yes, websites under hepson.pl are running correctly

administrator@lemon:~$ dig hepson.pl

So 217.113.235.103 is your server's public IP?
Is this server located in a data center, or maybe at home or in your office?

[webcitron]

Yes, it's my public IP. Server is located in my office, but I talked with my ISP, he said that the port 25 is blocking (so I send emails from another port). He don't said about any blocked ingoing ports.
Sory for my english, it's no good but I hope that you understand what I mean )

That's what I assumed.

[webcitron]

I can send emails, but I can't receive them. I called to my ISP a few minutes ago, now port 25 is unblocked and my email account don't receive emails ;\
Another ideas ?

[falko]

Do you see any errors (or any activity at all) in your mail log when you send an email to that server?
