hang on. tpop3d hasn't crashed here; it's received an
error from the network layer. Not sure why yet.

This could be an error in the buffering code, I suppose. I
doubt it's to do with the message format in detail --
tpop3d only looks for From_ lines and blank lines. Have
you access to any other version of openssl? I'd be
interested to know whether compiling it with a different
library version makes any difference in your
configuration.
