Version 3.32
------------

1. Eximon's call to XawTextReplace to empty the queue display was using a very
large number to indicate "end of text". This works with many X libraries, but
it was failing on the library in the RedHat 7 systems. Wrote the proper code to
maintain an accurate count of the number of characters displayed. However, it
still doesn't seem to solve the original problem, but as it is "better" in some
sense, I've left it in.

2. Added #define SIOCGIFCONF_GIVES_ADDR to the OpenBSD os.h file.

3. Arranged to give correct data length to bind() function for IPv4 sockets
when compiled with IPv6 support. Some operating systems check.

4. Cleaning up the auths directory was omitted from "make clean".

5. Bodged a fix to pcre/pcretest.c so that it will compile with gcc 3, which
doesn't like #ifdef in the middle of macro arguments - it has defined printf()
as a macro. Sigh.

6. If a delivery in a subprocess (local or remote) opened a connection to (for
example) an MySQL server, that connection never got properly closed because the
cleanup function was called only in the main process. Calls to the tidyup
function have been added to the subprocesses.

7. Reworked the way the daemon sets up to listen for IPv4 addresses on IPv6
systems, because on some systems the TCP/IP stack doesn't pass incoming IPv4
calls to listening IPv6 sockets because of security concerns. Using separate
sockets should work in all cases. Also, for listening on explicit interfaces,
IPv4 sockets are now used for IPv4 addresses, instead of mapped addresses on
IPv6 sockets.

8. When any "Resent-" header existed, Exim was using "Resent-Subject:" as the
Subject header for logging. This was a delusion on my part: RFC 822 never
defined Resent-Subject: so the ordinary Subject: should always be used.

9. RFC 2822 has abolished Resent-Reply-To: as a header. Exim now just looks as
the ordinary Reply-To: even when there are Resent- headers in the message.

10. OpenLDAP 2.0.6 represented an unset hostname as "" instead of NULL; Exim
had code to cope with this. Later releases of OpenLDAP have reverted to NULL
instead; unfortunately Exim's code, which was supposed to cope with either
case, was broken. It has been fixed.

11. Drop an SMTP connection if more than 5 unrecognized commands are received.

12. Tab was not being counted as a printing character, so if it appeared in a
a "fail" message (for example) it was printed as \t in log lines and in bounce
messages. Now if you use a tab, you get a tab.
