Errors-To: was needed only to take the place of the envelope sender in the days
when most Unix delivery agents couldn??™t differentiate between header and envelope.
The Errors-To: header should never be declared in the configuration file.
25.12.19 From:
The sender RFC2822
The From: header lists the address of one or more senders, where each sender address can
be in one of four legal forms:
address
Full Name
address (comment)
When the From: header lists multiple senders (in the sense that there can be multiple
authors) each must be separated from the others by commas:
From: address, address
Here, address specifies sender mailboxes, and eachcan be in any of the four basic forms
shown earlier. When multiple senders (authors) are in the From: header, the presence of the
Sender: header (?§25.12.35 on page 1166) is mandatory and must show the address of the
agent responsible for actual transmission. When a single author is in the From: header, and
when the author and transmitter differ, the Sender: header must show the address of the
actual transmitter. When author and transmitter are the same, the Sender: header can be
omitted.
A From: header must be declared in the configuration file, and its field is composed of the
$x (?§21.9.103 on page 851) and $g (?§21.9.47 on page 824) macros. For example:
H?F?From: $?x$x <$g>$|$g$.
