I do have a test machine but getting enough email into it for testing  
will be a daunting task. (see below) I'm primarily in the research  
phase now and testing will come next, after I have some solid info  
that will support Dovecot.

Your experience is what I was looking for. It confirms what I  
suspected. Thanks.

Are you aware of any vacation message solutions that work with the  
Sieve plugin? If the vacation message could come from a file or a  
database, that would be ideal. Or is it possible for Sieve to call a  
shell script or accept the vacation message via a pipe?

It's a migration but I'm migrating from EIMS, which makes things  
problematic. EIMS is a Mac email server that is quite good.  
Unfortunately, it does not handle IMAP very efficiently. It also  
stores email in it's own file format and that format uses Mac  
resource forks. Probably the only way I'll get existing email moved  
is to connect via IMAP to both servers and copy the files. I'm  
expecting the whole process to be somewhat painful....
