Mail server now filters blocked-subjects before applying DNSBL tag.
Received message header TO and FROM fields are no longer checked against the
email.can file for SMTP-authenticated clients.
SMTP MAIL FROM and RCTP TO addresses are no longer checked against the
email.can file for SMTP-authenticated clients.
Statistics are displayed in a more legible manner when the mail server is
terminated.
The msgs_received stats counter now includes blocked and ignored messages too.

Status display is working now.

system (in a multi-computer BBS) the error occurred.
For the mail server:
- keep track of the number of times each mailproc handled a message
- display counters when blocking/filtering messages in log output
- advertise 8BITMIME in the ESMTP EHLO response
- do not route mail to mailproc when the execution requirements are not met
  (e.g. ARS, DNSBL, SPAM, etc.)

Increase some log entry levels from LOG_ERR to LOG_CRIT.
Changed spam.log entry for spam-bait messages from "REFUSED" to "IGNORED".
Added several statistics counters for connections/messages refused, ignored,
etc. and display the values when the mail server is terminated.
Handle lines of exactly MAX_LINE_LEN chars better in sockmimetext() - don't
add an extra blank line between lines.

  SPAM-bait takers by using the mailproc.ini keys ProcessDNSBL and ProcessSPAM
  (default: True) respectively.
* sockmimetext() (used for sending message text over SMTP and POP3) now handles
  lines longer than 998 characters correctly (doesn't drop any characters).
  We may need to change this function to split at 510 chars for POP3 and/or use
  quoted-printable content-transfer-encoding for messages with long lines.
* "!SMTP ..." log lines changed to "SMTP ..." for non-terminal SPAM-related log
  entries.
* Handle header "field : value" syntax for subject, from, and to field parsing
   for early filtering.
* Don't tag message (subject and/or header) from DNSBL-listed servers when
   DNSBL_IGNORE option is set.
* Don't hash message subjects < 10 chars in length (too short for SPAM
  detection).
* Support Base64 and Quoted-Printable Content-Transfer-Encodings in SMTP
   message headers (decode and store message body accordingly).
* Clear mailproc 'to' match results when receiving SMTP MAIL FROM command.
* Allow SMTP authenticated clients to feed the SPAM database by sending mail
  to one of the spam-bait addresses (the sender won't be added to
  spamblock.cfg).
