Especially the <TT>map</TT> commands need a closer look. These lines
map local parts of the given address towards a full RFC 822 compliant
email address. <I>map_return_path_addresses</I> does this for the
passed <I>Return</I> address, <I>map_h_from_addresses</I> for the given
<I>From</I> part.
<BR>
But, pay attention! As you can see the strange name <I>gmx_foo</I> in
front of both items has never been seen until now. And in
<I>allowed_mail_locals</I> you see the same item. What about this?
<BR>
An E-Mail will be passed towards the E-Mail provider giving a so
called <I>envelope</I>. This construction envelopes the real E-Mail
and passes important things like the address of the sender and the
address of the receiver to the E-Mail provider. These envelope date
will never be seen again on the receiver's site, because the MTA
running on receiver's host will delete them. But only the envelope is
valid for any MTA distinguishing the route towards the receiver. So,
it must be a valid address.
<BR>
Per default <I>MasqMail</I> uses the current <I>user-name</I> as
<I>Envelope-From:</I>. If we want to use different E-Mail accounts
with mapping of addresses via the above shown <I>map_return_path_addresses</I> and
<I>map_h_from_addresses</I> we have to to <I>mutilate</I> the envelope
data!  That could be done very easily within <I>mutt</I>.
