The mailing list for listmasters using Sympa

[Steve Shipway <address@concealed>]

If the list is set to 'Reply to sender, *respect original Reply-To*' then it 
should work.  If you just have 'forced' then you'll be getting replies going 
to the list.

My patch sets 'reply-to' to be the original sender.  So, provided your list 
respects this when setting the reply-to, you should be OK.

An updated version of the patch is going to allow three address options -- 
list address(default), explicit, and original sender with .invalid suffix.  
This would also be an option (though replies would end up getting lost...)

And that did it, we couldn't keep blocking yahoo.com and now add aol.com
users too, so we've applied Steve's patch on production and it's working
great.  Thanks Steve!

But there is one problem: If someone has their list's reply_to_header
setting set to "sender" and "forced", Sympa will add its own Reply-To:
based on the munged From: line (ie. with the list address), overwriting
the fixed-up Reply-To: that was added by the patch.  So replies now
suddenly are going back to the list, but only on lists where the admin
actively tried to be sure they would go only to the sender.  And they
don't seem to appreciate the irony!

I can see ways to handle that problem with the forced reply setting, but
I want to be careful about handling the different edge cases: forced
reply_to in sympa, anonymous_sender mode in sympa, explicit Reply-To in
the original sender's email settings, etc.

Before I dive in, any thoughts Steve?
