[otrs] ignoring email messages

Hi all, for some reason, my otrs is ignoring messages form a host/domain (not sure) problem is that I can’t find any message rule or what so ever. I do not have any ignore messages settings at all! Jan 9 02:06:02 SIJN-Q02 OTRS-PM3-1[7949]: [Notice][Kernel::System::PostMaster::Filter::Match::Run] Set param 'X-OTRS-Ignore' to 'yes' (Message-ID: <47841D87.2080306@eset.sk>) Jan 9 02:06:02 SIJN-Q02 OTRS-PM3-1[7949]: [Notice][Kernel::System::PostMaster::Run] Ignored Email (From: Thomas Wouters , Message-ID: <47841D87.2080306@eset.sk>) because the X-OTRS-Ignore is set (X-OTRS-Ignore: yes). The weird thing is that this only happens with messages from noreply@eset.sk (did not try it with other .sk domains) but all other traffic/sites acts and work normal! Could any one of you do some suggestions where to look? Kind regards Thomas Wouters
