I have created 3 ACL rules with the sysconfig - Core::PostMaster.

1:
Module = Kernel::System::PostMaster::Filter::Match

StopAfterMatch = Yes

Match =>              Subject = SomeNumber:(\d\d\d\d)

Set =>                    OTRS-Valid = yes

2:

Module = Kernel::System::PostMaster::Filter::Match

StopAfterMatch = Yes

Match =>              X-OTRS-Queue = [a-zA-Z]

Set =>                    OTRS-Valid = yes

3:

Module = Kernel::System::PostMaster::Filter::Match

StopAfterMatch = Yes

Match =>              Subject = .

Set =>                    OTRS-Ignore = yes

If I try to create a new tickey by e-mail the support mail this will rejected by otrs. This is correct but it will also rejected when I have a ticketnumber in the subject or an OTRS-Queue header in it.

Why StopAfterMatch is’nt working?

Thx in Advance!
