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. Regards Peter Kruppa

I set up a Postfix-Server on my Fedora 21 box, which is connected to the internet via some Netgear Router. My private LAN is 192.168.10.0/24 with the Fedora box fixed on 192.168.10.1 . My Netgear thing has got a fixed IP and hostname, let's say for mydomain.com . Now I can - send myself mails from my Fedora box - send mails from my Fedora box to the outside p. ex. my googlemail account but I can't receive mails from outside. When I do a # tcpdump -n -i any tcp port 25 on my Fedora I can see many messsages like 10:34:09.338691 IP 212.227.17.11.64945 > 192.168.10.1.smtp: Flags [S], seq 3273717964, win 14600, options [mss 1418,sackOK,TS val 1273019143 ecr 0,nop,wscale 9], length 0 10:34:10.339378 IP 212.227.17.11.64945 > 192.168.10.1.smtp: Flags [S], seq 3273717964, win 14600, options [mss 1418,sackOK,TS val 1273019393 ecr 0,nop,wscale 9], length 0 [...] Any good ideas, what else I can do to analyze my problem?
