When I write new Email-Ticket I can choose the queue "From", but i can not choose the signature from defined ones in Admin - Signatures.

I have got several queues and every queue should have different signature (the amount of signatures = amount of queues). Is it possible to choose the signature or define it automatically for choosen queue?

You can set up different signatures for each queue in the Admin section. http://doc.otrs.org/2.1/en/html/x861.html#adminarea-signatures Nils Breunese.
