sendmail + imap (virtual host) + aliases

[Christopher Luk <bbwan@xxxxxxxxxxxxxx>]

dear All,

may be some one have asked before. i m using sendmail + imap where 
virtual domain and aliases are needed. after googling for some days, i 
still find no way to make it work. i can manage to get sendmail + imap 
with virtual domain on thru. mailertable, but no good on the aliases. 
any one can give me some hints. btw, i have noted there are links to 
anfi.homeunix.net which seems to be related but the links are all 
discontinued. is it related?
