Hmm, personally I'd prefer 2) over 3), e.g. because there is no need for 
the symlinks, unless other tasks/services _rely_ on the existance of both 
dirs.

Choosing between 1) vs. 2) I'd ask, who is going to login: If you have 
both user1 at acme1.com _and_ user1 at acme2.com login, use 2), 1) otherwise. 
But stick to one way for all for sake of maintainability.

Variant 2) has the drawback, that you have two distinct user entries with 
a different password. However, I guess, you can manage to write a SQL 
query to map both users to one entry in Dovecot, but what about other 
services?

Bye,
