Thanks to Soji Ikeda for accepting this patch into the tree so quickly!

The original patch is supposed to set the 'from' as the list address, but
additionally set a Reply-To of the original sender unless a Reply-To already
exists. In this way, if you have a Sympa Reply-to setting of 'reply to
sender' with the 'respect existing reply-to' set, it will continue to work,
though if you set 'force' option it will behave as you mention.

Generally speaking, though, I think there should be no need to 'force' if you
are setting reply-to:sender, as it is very unlikely that a sender would add a
reply-to:list header themselves. Any pre-existing reply-to would most likely
be for some version of the sender address. You'd be more likely to 'force' if
you want reply-to:list.

I agree that wwsympa should respect any Reply-To header when you click 'reply
to sender'.

I've made an updated patch that allows for alternative formats in the From
email address (as well as the From friendly name) so that you can have
$from.invalid as well as $list@$host and $explicit; however I've been held up
so haven't submitted it yet. Soji has worked too fast for me! I'll submit
an additional patch suggestion for this.
