That's my experience aswell. Courier attempts to consolidate this with
authlib, which is definitely handy for any authlib capable software but only
when the authentication specifics are the same and only for authentication
and maildir location.
Postfix allows the server and base to be specified in the conf for the
specific query ie:
server_host = spike
search_base = dc=internal
query_filter = (|(mail=%s)(maildrop=%s))
result_attribute = maildrop
Which I think is great as it allows you to keep the query and and connection
together and easily facilitates queries to multiple servers ... which can be
based on other factors such as which domain is is being queried at the time.

I had planned on using ssl but had also planned on upgrading to my domus
amd64. Do you know what the specific problem was?
