Post with different address?

[Anders Melchiorsen <postmaster@and.nospam.kampsax.k-net.dk>]

I have set some posting styles to let me use a different, spammer
confusing e-mail address (see above) when posting to widely spread
groups or mailing lists. However, I still like my unaltered address to 
be used in personal e-mails.

The problem is that if I reply (as opposed to follow up) in a
newsgroup the obfuscated address is still used. Is there a way to,
within the same group, use a different address for replies than for
follow ups?

I guess I am looking for some clever function to determine if I am
replying or following up, but I am not too fluent in Lisp so I cannot
figure out how to implement this, I must sadly admit.

I would much rather implement this as part of the posting styles than
as some hook, but if a hook is the only way I will definately
appreciate response on how to do that.


The relevant part of my posting styles looks like this:


(setq gnus-posting-styles
      '((".*"
         (address "postmaster@and.nospam.kampsax.k-net.dk")
	 )

	("^nnml:mail\\|k-net\\|list.netgrp"
	 (address "name@real.address.dk"))))


Thanks!
