The most likely problem table is "sender_canonical_maps". By the way I
strongly don't recommend using different settings in the sender and
recipient canonical mappings, who's a header sender and who's a header
recipient is in the eye of the beholder (consider what happens in
replies). Making these different has poor semantics.

This uses "%s" (full address with domain), so should touch remote
addresses. You could however configure a list of domains:
domain = foo.example, bar.example, ...
which are the only ones to look up in LDAP. On the other hand,
what is this table doing, "csimFullName" does not sound like
a mail address. Are you trying to include/update display names
in the canonical table??? That can't work.

Something is not right here, that address should presumably not be

Your LDAP schema/data is broken. The "mail" attribute needs:
- To be single-valued
- To be the primary address of the user
- MUST NOT be used for forwarding addresses, use a different
attribute for that.

Your LDAP schema is a mess, you need to solve the problem at a different
layer. See some of the examples in LDAP_README.
