Ok, I did today actually 3 tries at cutting the ZMailer 2.99.50s18 out..
First of all, smtpserver's 'DATA' command crashing at 2.99.50s17 was bad :-(
But I wasn't at all happy with some other things either. ChangeLog below.

* VERSION 2.99.50s18
BASE64 encoding of 7 chars long name yields a BASE64 string
with two '=' chars, that was considered bad by the decoder..
( I think there should be only one '=' char, but Netscape
Communicator 4.51 does it that way :-( )
Old (very old!) 'old-vs-new' scheduler locking scheme
causes problem at Solaris 2.6. Peter IP (Toronto) got
ZMailer router process pids 6/7/8/9, which the router
treated somewhat poorly..
Autosense OpenSSL at default location, if not otherwise defines.

Move openlog() a couple lines down so that also interactive
routers will use it.
Change the Received: header 'id' information to be the same
which syslog() uses, and which is reported at the smtpserver.
Eases looking for message spoolids at syslog outputs.
Overhauled error processing in various situations, now an
EX_TEMPFAIL condition will use next MX server (if one is
available) very much independent of where along the code
the problem occurred. Originally a problem in e.g. connection
setup until EHLO/HELO probe was retryable to an MX, but now
a much latter problem phase (DATA + . yielding 4** code,
for example) can do the same.
Latter continued the theme with logging of the smtp client session
to one client with weird looking problem: Ah, finally some clue
on the PIPELINING problem; smtp_sync() ignored (or treated poorly)
certain way how EXIM responds when it has disk full. We missed
the initial MAIL FROM-> 4** code, and errored with the latter
"503 No sender yet given"... D'uh.. (Likely this was entirely
ZMailer problem, but was it only introduced yesterday, or has it
been lurking there all along with PIPELING, and never spotted
before ??) It manifested as never accumulating queue to sites
using PIPELINING, and behaving like above..
* smtpserver/smtpserver.h, smtpserver/cfgread.c,
Much work again, now to parametrize ways of selectively adding
pieces of "Received:" header contained commentary information.
Features: ident, whoson, auth-username, tls-cipher, tls-client-cert
Added also: "PARAM AUTH-LOGIN-also-without-TLS" which allows
paintext "AUTH LOGIN" to be used without successfull STARTTLS.

Fix introduced accidental NULL referral.
Partially undo previous change to SiteConfig.in;
let the FORCEPUNT to be there...
* scheduler/scheduler.c, scheduler/update.c:
Fixed the 'stored recipient count' gauge leakage.
