Thanks for your reply. OK I'll bear that in mind. I don't _think_ that's
the problem here though. How would I change the port if I wanted to do
so?

That's cool -- I don't care who the email looks like it came from, as
long as it gets to the other end ;-)

Yeah, the log file said something about that -- unfortunately I couldn't
find in the readme where that hosts_require_tls should be set and a
Fletcher classic find / grep combination of the exim-relevant
directories I know about failed to turn up which file this setting needs
to be in. Could you enlighten me?

Thanks. Didn't know that.

Unfortunately, it doesn't appear to be that.
ldd /usr/sbin/exim-4.63-1 gives the following output:

/lib/ld-linux.so.2 (0x80000000)
libz.so.1 => /usr/lib/libz.so.1 (0xb7b0a000)
/usr/lib/i686/cmov/libssl.so.0.9.8 is contained in the Debian package
named libssl0.9.8, version 0.9.8c-4etch1 of which is installed on my
machine. The version number of libssl-dev I have is... wait for it...
0.9.8c-4etch1. While we're about it, libcrypto.so.0.9.8 is also provided
by libssl0.9.8 and hence is at the same version.
I had a look at the files in the libssl-dev package, and that led me to
look at /usr/include/openssl where a ton of files are provided by this
package. There I found a tls1.h which is just a bunch of #defines --
including a TLS1_VERSION set to 0x0301. Clearly this doesn't relate to
the version number of the openssl library but it was a piece of
information I didn't have before, which someone might make something
of...
Any other ideas?
