Hi,
I'm receiving a lot of spam in  my old email account...
I'm even receiving emails with my own old email as sender!! :-(

Is it a way to tell the sysadmin of this email provider to add some kind 
of scripts for automatic sign all the outgoing emails (in the name of 
the department)?
Or maybe the solution has nothing to do with GPG?

Thanks
