Hi, I tried to use the POP filter mechanism like this: Match: Header1: Subject; Field: *snom190* Header2: Body; Field: *snom190* Set: Header1: X-OTRS-Queue; Field: support::phone-support::snom190-queue But with this filter set, the pop is failing at all, so no mail is coming in, but the log says something like: otrs@fox:/opt/otrs > $HOME/bin/PostMasterPOP3.pl Message 1/5 (tts@yyy.de@post.xxx.de) /(*media*server*)/: ?+*{} follows nothing in regexp at /opt/otrs/Kernel/System/PostMaster/Filter/MatchDBSource.pm line 67. How can I achieve to match the filter to anything in i.e. the subject, if at least snom190 is somewhere in it ? Are the different header lines like an "OR" and the first line is tried first and so on ? Regards, Sven
