Znuny/Znuny LTS is a fork of the ((OTRS)) Community Edition, one of the most flexible web-based ticketing systems used for Customer Service, Help Desk, IT Service Management.
Znuny uses hardcoded 3s timeout for DNS queries while checking MX
(if CheckMXRecord is enabled). 3s may be too short in some scenarios
(sporadic errors in MX validation of remote addresses). DNS timeout
should be configurable to allow admin to fine-tune this setting.
This mod introduces new SysConfig parameter ResolverTimeout that
allows one to set custom timeout for DNS queries fired by Znuny
(now only for CheckMXRecord algo).
