Majordomo aliases

OK, I *really* need to get my majordomo account fixed up to keep from
stalling posts from my various accounts to the various lists. 

I think that I can enter some aliases etc to allow this; where do I find
out how? Searching the -hackers archives brought no joy since the
obvious keywords show up in every stinkin' mail message ever run through
the mailing list :/

Any help would be appreciated...
