Per User Relaying

[Alex Neuman]

Milter sender has a problem with some non-rfc2822 compliant servers that
don't accept <> as an originator. You can still modify the original source
code to say something like "<postmaster at yourdomain.com>", for example.

The sendmail milter-ahead or milter-sender plugins may help out with this
functionality, yet I do not know how that would affect MailScanner.

I have a smartrelay host that I am considering doing the milter-ahead on,
but I am not running MS on it. So the conflict is not there for me.

The milter-ahead is more fitting to your request, but the milter-sender
would help too.

milter-sender: http://www.snert.com/Software/milter-sender/index.shtml
milter-ahead: http://www.snert.com/Software/milter-ahead/index.shtml

Let me know if you go this route and it is configurable with MS.

Keep us posted of your progress.

Thanks Ken,

Same error.

Maybe I'm missing a feature in sendmail? I don't know.
