Don't know for certain but looking at the error message it give the hint that the error is related to DNS.  Is the server able to resolve DNS (MX & A) queries?  My first look is whether name server resolution is functioning.

Hi All
 
 
When I try to Reply to a ticket I get this:
 
Software error:

For help, please send mail to the webmaster (root@localhost.localdomain), giving this error message and the time and date of the error.
 
 
We have been using OTRS for more than 3 months now, with no problem. Today we got this, with no aparent motive.
 
Does anyone know how to fix this?
 
Thank you,
