    Ummm... not so much. The last released version of FWTK still has locking
    bugs in the SMTP proxy that can cause problems (definitely wedged mail,
    maybe lost mail - my memory is fuzzy). I'm pretty sure there are patches
    floating around that fix them, but I'm not sure. I fixed some of them, and
    Viktor Duchovni fixed more (well, he rewrote most of the proxy), but we may
    have fixed the Gauntlet source, not fwtk, so I don't know if they were ever
    released...

    Apologies for the FUD-like post, but it has been 4+ years since I looked at
    any of this...
