As already stated, this solution has been working for approximately 6
months. Mail is being delivered perfectly. Spam filtering is great. The
only problem that has occurred is with forwards created in .qmail files
placed in an account's base directory alongside the Maildir/ directory.

I showed you the complete log chain before, it says the message is
delivered, no deferral occurs, and there's nothing in the local queue.
