We have a hacked zmailer that will support mail-domains that each has 
there own alias file. It uses a changed set of xxx.cf files so all of the 
zmilaer C source would stay the same. The main problem is that the 
version of zmailer we are based on is quite old.

I have looked at the cyrus IMAP server and it looks as though that server 
could be easly hacked to work from a different password file connect to 
POP/IMAP users through an IP->configf-file mapping.

I have some time I can allocate in the effort to help put the pieces 
together.
