This is my principal complaint. This is not an 822 issue; this is a
local-part parsing issue, for a syntax that never leaves the host. What you
want is a syntax that will never show up in a real E-mail address (i.e. one
transmitted over the wire in SMTP), and never show up in a real user name
(from /etc/passwd or whatever your user name database is for your OS).
Sendmail's choice is unfortunate for its collision with one of RFC822's
quoting mechanisms, however I have never seen it cause a problem. I don't
like Eugene's (smail) suggestion because that potentially collides with
real (ahem!) user names (though I'm glad someone other than me has seen
this as a problem and worked on it some!).
I really want to be able to support:
in my .forward files, and in /etc/aliases (for those who do not know, this
is sendmail's syntax for saying "leave one copy here in my system mailbox,
and send another copy to firstname.lastname@example.org" (It's also possible to put a
pipe/program delivery, or a direct-file delivery here)).
Sendmail's rules are explained in an "aliases(5)" manual page that comes
with the distribution. It would be a really good idea for there to be a
similar page for zmailer (potentially one for each different aliases.cf
file that one could use).
