lmtp_downcase_rcpt patch for 2.2.1-BETA

[Eric Estabrooks]

I haven't paid much attention lately on the list so I don't know if this has been submitted already or not. lmtp_downcase_rcpt doesn't downcase the domain when it downcases the mail user name. If you are using the virtual domain stuff this means that if your domain is lowercase and the user gets sent a mail message with the domain mixed or all upper it'll bounce with user unknown.

Attached is a patch to lmtpengine.c that addresses this issue.
