Hello Community,

I am trying to figure out what would be a "best practice" when one has a 
of domains on which it receives mail to and from which it sends mail from.

For example I have the following domains:

I have a user 'valentin' which has the following E-Mail addresses:

     valentin at
     valentin at

The users are authenticated from OpenLDAP and the mail attribute is set to
valentin at The mailAlternateAddress is set to 
valentin at
I plan to use the Lachman LDAP Mail Routing Draft [1] and schema.

Should I create in Cyrus IMAP two virtual domains and a 'valentin' user 
for each
of this domains or would it be better to create a user 'valentin' where 
to post
the E-Mail messages I receive on both domains?

Then the MUAs could be configured with multiple identities and have only 

What are the gotchas if I choose to go one way or the other? And do you 
that [1] is 'stable' enough to be used?


Cheers and Goodwill,
