Posting to PHP newsgroups with Opera

Have you managed to get “Opera’s”:http://www.opera.no/ news reader to post to the “PHP newsgroups”:nntp://news.php.net ? I have not been able to figure out what settings to use for the outgoing server - Opera implies my mail server, but this doesn’t seem to work.

I need to post to the PEAR list, but can’t subscribe to the email list and get so many messages
Help!
