Reply-To:
Alternative reply address RFC2822
The Reply-To:
header requests that replies to messages go to an
address that is different from that of the original
sender. This header is usually inserted by
mailing-list software, where the From:
is the address of
the author of the message and the Reply-To:
is the address
of the list.
The field for the Reply-To:
header must obey the same
rules as those for the From:
header’s field. One example of
the use of this header might look like this:
From: bob@list.server.domain Reply-To: mailinglist@list.server.domain
The Reply-To:
header should never be declared in the configuration
file.
