[otrs] OTRS 2.0b2 - Queue Management "Sign Key"

Hello and greetings from Japan - In OTRS 2.0b2, queue management screen, there is a "sign key" selection. Is this related to the new SMIME or PGP admin options? Also, if I set up SMIME and/or PGP, does the recipient have to be set up some how as well? Are these a way to prove that the mail came from my OTRS? Appreciate any help on this - TIA!!
