Change "Email hiding" text

[massar]

webroot/site/edit_contact.html

change:
"Email hiding: Hide my domain name when forwarding group e-mails"

into:

"My mail server won't accept mail purporting to be from my domain.
This option hides the domain name when forwarding group e-mails.
Should be enabled when your email domain has SPF filtering enabled"

Also add options:
[X] Email rewriting: My mail server won't accept mail purporting
to be from my domain (e.g. because of SPF)

and then add Radio options:
@ always include me in Reply-To
O only put me in Reply-To when no Reply-To is present
O do not include me in Reply-To

so that people can select their fancy.

Also, instead of setting From: $common::sender ($from), set it to:

From: "Real Sender [email protected] via ListName" [email protected]

To indicate in the header (that people see easily instead of the comment), that this operation was performed. Also, that make people pressing to reply to the list work and not bounce to mail-handler.
Though Reply-To and Mail-Followup-To should resolve that too, in non-broken MUAs.
