Even though some remailers can post directly to Usenet, premail does not support that. Thus, if you want to post to Usenet, you should use a mail-to-news gateway.
To find a working mail-to-news gateway, check Don Kitchen's list. There are two basic kinds: sites that scan the header fields, and sites that include the newsgroup in the address.
Using the address-parsing kind, to post to alt.anonymous, you'd just send mail to alt.anonymous@myriad.alias.net (assuming, of course, that myriad.alias.net is still functioning).
Using the header-scanning kind, send mail to mail2news@myriad.alias.net, and include this header field:
Newsgroups: alt.anonymous
The header scanning kind has one advantage: you can cross-post to multiple newsgroups using one mail message.
One frequently asked question is: how can I follow up on a thread
while posting anonymously? This is easy. Find the Message-Id:
header field in the post you're responding to, and change it into a
References:
field in your outgoing mail.
Here's an example that ties it all together. Let's say you wanted to reply to this post:
From: Edward Brian Kaufman <ebk8@columbia.edu>;
Newsgroups: alt.privacy.anon-server, alt.anonymous
Subject: A few questions about anon posts

Hi,
I'd like to know what the best/easiest way to do anon posts is and
how to do them. Thank you,
Ed

If you have a Unix machine, using premail is the best way. To find
out how, read the manual.
