[9fans] pipefrom fun

[maht-9fans]

All being well this is a mail routed by my pipefrom

/n/sources/contrib/maht/rc/pipefrom

It has seen the outgoing address  of "9fans" and changed it to "9fans@9fans.net"
It has seen the outgoing address of "9fans@9fans.net" and set upasname to be "maht-9fans@maht0x0r.net"

why not use /mail/lib/names.local for the first example?

i haven't read the script, though.

; ls -l  /n/sources/contrib/maht/rc/pipefrom
--rwx--x--x M 675 maht sys 1107 Aug 20 20:50 /n/sources/contrib/maht/rc/pipefrom

one thing i've thought would be useful since people mail from
many places with many names is a translation from a set of from
addresses to a mailbox name so that, e.g. the ned f command doesn't
end up creating a bunch of folders for the same person.

pipefrom is too late to rewrite outgoing addresses,
because marshal has already written the To:
line with the local address.  Your post says
    To: 9fans@steponnopets.net
You can create /mail/box/$user/names
to get aliases that won't go out.

good point, upon my brief look the answer would be, although I can
contrive upon boot to use a different file, in the general case, users
can't edit it.

I'll consider that when I get round to pipeto

I submitted a patch for marshal to do the From: part but was told I
should use pipefrom instead. I'll stick a sed in the send see how that
works out :>

dammit, I obviously had missed that when I was testing it

that has nothing to do with pipeto.  it would be a big mistake
to modify the sender in an email!  the dread libcommon needs
modification.

little known fact:  mail quanstro/folder will deliver directly to
folder rather than inbox.  many email gateways dislike this,
so you can rewrite
\l\.quanstro.net!([^+]+)\+([^+]+)	alias		\1/\2

if you're using nupas, which is a good idea if you have an internet-
facing smtpd, i'll consider patches.  but i'm a little leery of adding
yet more complicated rules for frobnication of the sent message.
does your script work with mail sent through the imap server?

since you set upasname, marshal already tries to add
/mail/box/upasname/headers, this already solves all of your problem
except setting upasname automaticly.

finally, the reason your To: address did get rewritten is that send, which
is invoked by marshal does yet more rewriting of the from,

They're separate issues, which might not have
come across in my earlier mail.

Rewriting of To: must be done in marshal and is
supported by editing /mail/box/$user/names.

Rewriting of From: is the reason for pipefrom.

in the simple case, From:  can be rewritten with
/mail/box/$upasname/headers
