Fix matching of incoming email addresses to the alternate_addresses field... ...of a user -- this would match substrings, e.g. if the user has discuss-support@example.com as an alternate email and an incoming mail is addressed to support@example.com this would (wrongly) match. Note: I *think* I've seen this discussed somewhere but couldn't find it, neither in the tracker nor in recent discussions on the mailinglists. So if someone remembers an issue which now should be closed, please tell me :-)
