Deine mynetworks Zeile ist ungültig. Kommentier Deine Version bitte mal aus und nimm wieder die standard Variante:

mynetworks = 127.0.0.0/8 [::1]/128

und dann starte postfix neu. Du solltest da eh keine weiteren IP Adressen rein tun als localhost.

so war es ja standard und es ging nicht.
aus lauter verzweifelung hab ich dann mal die ips hinzugefügt.

gerade nochmal versucht nur mit localhost und es geht nicht.

die firewall ist es wohl nicht

aber warum ist der port 25 nicht erreichbar?

postfix sollte laufen:
Code:
# telnet localhost smtp
Trying 127.0.0.1...
Connected to localhost.localdomain.
Escape character is '^]'.
220 srv1.xxxx.de ESMTP Postfix (Debian/GNU)
 
#7
ich habs!!

in der main.cf steht:

Code:
# inet_interfaces = loopback-only
es muss aber sein
Code:
inet_interfaces = all
"all" für alle interfaces oder eine liste der ip-adressen oder hostnamen durch komma getrennt auf welchen postfix lauschen soll.
