[exim] [Patch] LMTP Ignorequota extension

Here's a patch for exim's LMTP transport, implementing the IGNOREQUOTA
extension to LMTP*. Set 'ignore_quota = yes' in the transport options to
deliver even to overquota mailboxes.

This has had minimal testing only, so please don't blame me if it eats
your email.

Adam.
