Hi, Im having a problem where a spamfilter triggers on the fact that OTRS does not set any sender on the autoresponse emails, it seems to be missing (no null-header or sender address) In the server logs i get '... otrs set sender to <> using -f ...' which is most likely the cause of this i guess? Is there any solution to this?
