Re: [tpop3d-discuss] tpop3d w/TLS

[Ben Schumacher]

Chris-

Here is the patch. I tried to cleanup the code a little bit, but it could
probably use some more work. I tried to make sure that everything that
was necessary only for use with SSL/TLS is wrapped in #ifdef's, but I
might have missed something.

The only gotcha is that since OpenSSL has builtin MD5 support, I had to
disable the bundled md5 code in tpop3d.

Let me know if you have any questions.
