Ok, I found the issue.
My Signing subject trigger is set to "(?i)(\[sign\]|\[signed\])" with
"Regular expr." enabled. If I send a mail with subject "test [sign]" the
message is correctly signed, with subject "test [signed]" the message is
not signed. However the subject is changed and the trigger keyword is
deleted.
The reason why "[signed]" is not workjing is that I defined "[signed]"
in the "Subject filter" which is set to "/\[(decrypted|signed|signed
by:.*|mixed content|invalid signature!)\]/".
So it seems that this filter is put on before and deletes the "[signed]"
keyword first and so the signing task never sees that keyword.
I guess that is working as designed?
Thanks,
Michael

I normally do not want all outgoing mails to be signed with my S/MIME

NOT be signed.
We have use a similar setup, i.e., sign message if the subject contains
the force sign keyword.
I just tested it with a fresh install of the gateway and it works. Are
you certain you checked "Enabled" under the "Signing subject trigger"
settings?
Can you provide the "Signing subject trigger" settings you use
(Trigger,
Regular expr.)?
The MPA log might provide more information. As to why signing was not
triggered.
Kind regards,

Is there a possibility to sign the message without encryption just on
a
case by case basis?
The reason is, that I want to sign a message explicitly if I want to
send a recipient my S/MIME key before we both have exchanged the keys
and would be able to encrypt the message.
Thanks,
Michael
