Unix From_ header lines with "remote from"
Brian Bullen
the "From " headers when delivering mail.
The Colour Book sendmail config defines the format of the Unix From
header as
DlFrom $g $d remote from $U
This causes a problem for users trying to use ELM when a filter program
is used to deliver the mail (via Mailer "prog").
Is anyuse made of this "remote from <host>" information - can we
deconfigure it from our From headers ?

That's awful.
The 'remote from' is supposed to get there via the 'U' flag in the mailer
definition, together with the mailer specific sender rewrite rule prepending
a "$U!" to the address. I should not be in the 'Dl' line.

The "remote from <host>" is used for UUCP mail; if the remote site is
using the vendor-supplied rmail(1) then they will need it. However,
there is more than one way of getting it there.
Check your uucp mailer definition. If there's an "n" flag then the
"From " line is being suppressed and the contents of the "DlFrom" line
will be irrelevant. (In this case the mailer is generating it's own
"From " line before calling uux(1)).
I should point out that there is also a "U" flag which will add a
"remote from <host>" to the "From " line; unfortunately sendmail will
complain if the sender's address isn't in the old-fashioned site!user
format.
