Wow, sooooooo old. When i was using "GNU Emacs 21.4.1, Gnus v5.10.7", i
remember i encountered similiar problems. And to solve it, you have to
update several gnus files. i found the link that used to help me, so you
may give it a try,

|     * Gnus: lisp/starttls.el 
| 
| and of course pop3.el in Gnus.

Good luck,
