Do the nameservers that you use in /etc/resolv.conf resolve the domain correctly? falko, May 17, 2012 #4 vaio1 ISPConfig Developer ISPConfig Developer Hi falko, yes the A record point directly to the right web server. In the webserver there is a mail domain with the name of the domain registered. Yes, the nameservers resolve correctly the domain.

I'm not sure, but maybe you should lower the expire - maybe this causes the problem. falko, May 18, 2012 #6 vaio1 ISPConfig Developer ISPConfig Developer How have I change the SOA expire time? thanks vaio1, May 18, 2012 #7 falko Super Moderator ISPConfig Developer Try 3600 instead. falko, May 19, 2012 #8 (You must log in or sign up to reply here.)
