And you're sending "250 ...\r\n", right? Not sending a proper SMTP line ending could confuse some clients and not others.

Also, is it possible the clients are timing out, because you're taking a very long time to process the message?

I find that using something like snoop/tcpdump or truss/strace is a great way of getting a reality check on what my program is really doing, as compared to what I think it's doing. :)
