+8.6.4/8.6.4    93/10/31
+       Repair core-dump problem (write to read-only memory segment)
+               if you fall back to the return-to-Postmaster case in
+               savemail.  Problem reported by Richard Liu.
+       Immediately diagnose bogus sender addresses in SMTP.  This
+               makes quite certain that crackers can't use this
+               class of attack.
+       Reliability Fix:  check return value from fclose() and fsync()
+               in a few critical places.
+       Minor problem in initsys() that reversed a condition for
+               redirecting the output channel on queue runs.  It's
+               not clear this code even does anything.  From Eric
+               Wassenaar of the Dutch National Institute for Nuclear
+               and High-Energy Physics.
+       Fix some problems that caused queue runs to do "too much work",
+               such as double-reading the Errors-To: header.  From
+               Eric Wassenaar.
+       Error messages on writing the temporary file (including the
+               data file) were getting suppressed in SMTP -- this
+               fix causes them to be properly reported.  From Eric
+               Wassenaar.
+       Some changes to support AF_UNIX sockets -- this will only
+               really become relevant in the next release, but some
+               people need it for local patches.  From Michael
+               Corrigan of UC San Diego.
+       Use dynamically allocated memory (instead of static buffers)
+               for macros defined in initsys() and settime(); since
+               these can have different values depending on which
+               envelope they are in.  From Eric Wassenaar.
+       Improve logging to show ctladdr on to= logging; this tells you
+               what uid/gid processes ran as.
+       Fix a problem that caused error messages to be discarded if
+               the sender address was unparseable for some reason;
+               this was supposed to fall back to the "return to
+               postmaster" case.
+       Improve aliaswait backoff algorithm.
+       Portability patches for Linux (8.6.3 required another header
+               file) (from Karl London) and SCO UNIX.
+       CONFIG: patch prog mailer to not strip host name off of envelope
+               addresses (so that it matches local again).  From
+               Christopher Davis.
+       CONFIG: change uucp-dom mailer so that "<>" translates to $n;
+               this prevents uux from seeing lines with null names like
+               ``From   Sat Oct 30 14:55:31 1993''.  From Motonori
+               Nakamura of Kyoto University.
+       CONFIG: handle <list:;> syntax correctly.  This isn't legal, but
+               it shouldn't fail miserably.  From Motonori Nakamura.
