I can confirm your problem.
We are running an usenet news server, where we allow users to connect
directly and without any form of authentication and encryption from
within our network, but force users to connect via SSL and
authenticate themselves from the outside.

Mozilla will hang when posting messages via an SSL-encrypted link.
It doesn't happen always. It appears to happen when writing the message
takes a little while. When the message is written and sent quickly,
mozilla doesn't hang.

We are running inn-STABLE-20041230, but the problem was there with
earlier versions also.
