Hi
Suddenly I can't receive mails from outside my domain anymore.
Mails from accounts within the server are sent and recieved normally.
Mail accounts on the server can recieve mails from mails outside.

Interfaces to non-Postfix software. Be sure to examine the manual
pages of the non-Postfix software to find out what options it wants.
Many of the following services use the Postfix pipe(8) delivery
agent. See the pipe(8) man page for information about ${recipient}
and other message envelope options.
====================================================================
maildrop. See the Postfix MAILDROP_README file for details.
Also specify in main.cf: maildrop_destination_recipient_limit=1
maildrop unix - n n - - pipe
flags=DRhu user=vmail argv=/usr/bin/maildrop -d ${recipient}
====================================================================
Recent Cyrus versions can use the existing "lmtp" master.cf entry.
Specify in cyrus.conf:
lmtp cmd="lmtpd -a" listen="localhost:lmtp" proto=tcp4
Specify in main.cf one or more of the following:
mailbox_transport = lmtp:inet:localhost
virtual_transport = lmtp:inet:localhost
====================================================================

hostname -f : hetzner.marketstrategy.de
mxtoolbox / telnet 136.243.54.13 25 : failed to connect
The Port 25 is not open for some reaspn.
periodicly mail.log creates hetzner.marketstrategy.de: [CODE]status=bounced (Host or domain name not found. Name service error for name=hetzner.marketstrategy.de type=AAAA: Host not found)[/CODE]
I'm absolutly out of ideas. pls help :[

From the forum index page :
This is not a general Postfix help forum - this is for the separate package PostfixAdmin which configures/maintains virtual domains & mailboxes using Postfix (plus MySQL or PostgreSQL, optionally maildrop, and Courier or Dovecot).
For Postfix help you should head over to postfix.org and check out the Postfix mailing lists.
It looks like an intermittent DNS lookup problem, so look at the route your hosts takes to do lookups.
As to port 25 not being open, check what ports are open locally (netstat -anp) and look at any firewalls that could be blocking it. Also, don't rule out the possibility of your ISP blocking port 25 - many do.
