Contacting mate-media maintainer, eg. gnome at freebsd.org not responsive?

[Georg Bege]

Hello people,

what would I need to do if I wanted to contact a maintainer which is not 
available/unresponsive?
Who's maintaining the mate packages, is gnome@ a generic alias?
I tried to come in contact some months ago but failed...

best regards,
