This is a bit different from the way Smail handles this line.
There seem to be quite a lot of UUCP-systems that don't include
the user in the 'domain!user'-way at the beginning, but rely
on the MTA to put the 'remote from' system at the beginning
giving 'system!user' as sender.

Why being that strict about the syntax of the From-line?
All Exim uses is the first field, the user field.
As far as I understand RFC 976, the only assumption that might
be made is that there *is* a username and a 'remote from'.
I guess 'remote from' should be looked for as a keyword (this
is the way Smail works in "queue.c"). Everything between is
the date (which is ignored), everything behind the system name.
Are there any definitions of the "From_"-line, beside the
one in RFC 976?
Greetings,
Georg
