Added email.can and subject.can checking as sysop-configurable SPAM filters.

Fixed potential NULL pointer de-reference bug (new).
Added support for external address aliases (you@somedomain.com  = sysop) in the alias.cfg file.
Now store original destination address in "name" field of SMB header.

Added real IP and hostname if different from sender's stated address.

Move SMB hfield creation for sender name and address to support RFC headers that are missing these fields
(uses reverse-path instead).

Uses ctrl/relay.cfg now instead of text/relay.can.

Also handles resetting daily user stats if online during date change.

Updated mail-abuse.org DNS and HTTP server addresses.

No longer logs (or displays locally) failed password attempts if the sysop has so configured the system in SCFG.

Now logs port number, host name, and IP address for POP3 sessions where messages are either downloaded or deleted.

Put single quotes around unsupported command lprintf's to help debug extra white-space chars.

Changed algorithm for detect IP address vs host name (now supports hostnames starting with a digit).

Added comments and clarified the code a bit.
"real.name" and "sysop.alias" will retain original receipt names in message headers now (whoa).
