So, hello again!
I "sort of" solved the problem by completely turning off my firewalld.
# systemctl stop firewalld.service
and to make it permanent:
# systemctl disable firewalld.service
(Just in case: Fedora docs say the same could be done with
iptables.service).
Of course this solution is not optimal - but firewall setup is a subject
for a new thread.
Big thanks to everybody on this list for your patient and competent
advice. That gave me a good starting experience with Fedora Community
and my new server system.
I will now unsubscribe pukruppa@xxxxxxxxxxxxxx from this list - my new
address ulrich@xxxxxxxxxxx is already on-line.
Thanks again
Peter

Hi everyone,
please do excuse my unspecific subject - I don't really know what my
problem is yet.
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],

ecr 0,nop,wscale 9], length 0
[...]
Any good ideas, what else I can do to analyze my problem?
Thanks for your answers
Peter
