for the recipient of posts.
When posting to a sub via authenticated SMTP, the sender/extension fields are
set appropriately and the sender net type is set to none (i.e. locally posted).
More debug log-level output for SPAM hash creation/checking.
Bug-fix: attempting to use uninitialized 2nd MX address when relaying to local
SMTP server address.

warning log level.
Added more debug log output.

error counting/logging/messages to be handled by front-end (e.g. control panel)
regardless of log_level setting.
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.

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).

"Normally, this response will be a multiline reply. Each line of the
response contains a keyword and, optionally, one or more parameters."
Added RFC1870 Message Size Declaration support to EHLO response.
Strip optional parameters from MAIL FROM command (per RFC1869).

* double spam.log entry ("TAGGED" and "IGNORED") for the same message
* DNSBL_IGNORE option did not work unless the DNSBL_SPAMHASH was enabled

created:
js.exec_path - full path and filename of file executed
js.exec_dir - directory of executed file
js.exec_file - filename executed (with no path)

Updated logged error messages.
More use of SAFECOPY/PRINTF macros.
Eliminated DNSBL_DEBUG option (redundant with debug log level).
Optional SPAM-hashing/checking support.

thread-safe.

(and not the RFC882REPLYTO header field), send the Reply-To header as
Reply-To: "name" <addr>

with the ARS HOST and IP keywords (and the AccessRequirements key).

Added HOST and IP keywords to allow restricted access/privileges to/for
specific remote hostnames or IP addresses (wildcards allowed).
All string-argument type ARS keywords (e.g. SHELL, PROT, etc.) now support .can
style wildcards.
The current remote client is now used for protocol, host, and IP ARS checking,
when available, so this requires passing the client pointer around (which
explains why so many files are touched by this change) and takes care of a
long standing to-do item (the user's 'modem' value was used for the PROT
value checking, which was not always correct).

IP addresses (with wildcards) that the associated mailproc will run for.
Bug-fix: the SMB REPLYTONETADDR header field value would be created
invalid if the sender's Reply-To header field value contained a name, like:
"Rob Swindell" <rob@someserver.com>
Raise the log level of the SMTP ALIAS log lines from info to debug.
Generate an info-level log entry when receiving message text.

Constified the arguments.
Created exascii_to_ascii_char().
Created ctrl_a_to_ascii_char().
strip_ctrl() and prep_file_desc() now takes 2 args.
strip_ctrl(), strip_exascii() and prep_file_desc() now strdup() the input
string and if the dest arg is NULL, returns the allocated and modified copy.
sbbs_t::bputs() now handles ^AZ.
Change Ctrl-A code message network exporting:
1. ^AL, ^A<, ^A[, and ^A] are always translated to ASCII equivalents.
2. ^AZ will terminate the message body prematurely if found.
3. Ex-ASCII (CP437) chars will be translated to ASCII equivalents (rather than
'*') for "ASCII Only" subs.
For import, don't allow Ctrl-AP or Ctrl-AL.
For SBBSecho:
Added support for specifying a link's address on the command-line (e.g. for
use with -h).
Mail server now strips Ctrl-A codes from message bodies for sending via POP3
or SMTP.

Also, fixed the possible infinite loop in main.cpp output_thread() when send()
fails for the system output socket.

Defined 'recipient_address' convenience variable for JS mail procs and added %T

Also, on FreeBSD, SetThreadName() will silently fail if the name is more

Some overhaul of log levels in web server.

Eliminated some bcc32-reported warnings.

Fix bug where-by if a non-pass-through mailproc was addressed by an e-mail and
another recipient was addressed, the message would not be routed to the
mailproc.

Spam related messages and web server session timeouts.

- Fixed line counter/return value of sockmimetext() - did not count last line
if not \n terminated.
- If a POP3 "TOP" command is used to request more lines than there are bytes
in message body, just send all lines and don't log an error.
- JS mailproc error reporting and log() method now includes the mail-proc
name and the "SMTP" log prefix. "JavaScript:" is no longer included as part
of the log() output since that is implied by the mailproc name.
- js_mailproc() now reuses the same runtime, context, and global object to
speed up the initialization/execution of multiple JS mailprocs per message.
- Beginning support for messages to be bounced back to mailprocs (e.g.
ListServer), specifically by ignoring bounces of SMTP sys messages
(instead of all non-person agent types). More work in bounce() is needed.
