If you have the link at the bottom, Zammad will provide the same URL twice.
I think that this is not directly a bug, because normally we’d expect that the last line is not the URL (at least not in our Triggers and signatures )
Also please note that the signature URL you provide above leads to invalid URLs if you’re the one creating a new mail on a ticket (because the ID is not yet ready at that moment).
@MrGeneration: Thank you very much for your explanation!
Our problem can easily be solved with a workaround, so that the link is not at the very end of our signature.
Since we don’t regularly generate tickets with new mails ourselves, an invalid URL isn`t a relevant problem either.
So for us, our problem has been solved. Thanx again! :-
