I had a similar yet distinctly different situation -- I was unable to connect from behind an OpenBSD box with pf to an external Exchange host running IMAP. Things were in the same weird state. I was not using synproxy but I was using scrub's reassemble tcp. When I removed reassemble tcp, things worked like a charm. I've been so busy since then that I have not had a chance to debug it further, but hopefully this helps. -jon
