Trying to roll out PGP (GnuPG) support over certain parts of the company as per management directives. At this rate, I think I'll end up rewriting a Eudora GPG plugin so our various mailers work together.
Updated some lists to send bounce messages to another list which in turn sends its bounce messages to a person. After this, the remote machine this was done on stopped responding some hours later. Turns out that an ether hub had died. Phew.
