sid-milter questions

I am using sid-milter with postfix 2.3.3

b) send a reason of rejection to the mail sender ( currently blank just
a 5.7.1 )

Thanks

sid, as in sender ID ?

This is the SPF mailing list, not a SenderID support channel.

provided that you can use your milter to do real SPF: by letting
it do its work at the right place, i.e. in either
smtpd_sender_restrictions or smtpd_recipient_restrictions

I looked sid-milter up using google, was directed to
http://sourceforge.net/projects/sid-milter/

and found:

" Need Support?: See the support instructions provided by this project "

Sendmail's sid-milter supports both SPF and SenderID, so I don't see
this as being offtopic. You are right that the sid-milter specific
mailing list would probably be a better place, but there may be people
who use it who can answer here.

For what it is worth, Julian plans on supporting SenderID in his new
Mail::SPF perl implmentation. Just the mfrom part, not the pra, but
it is SenderID none the less.

FYI (I haven't used it, so I can't help the OP), SID Milter does both Mail
From and PRA checking. It predates RFC 4408, so it likely is not exactly SPF
checks, but I believe it's at least in the ballpark.

I didn't ment to say this was off topic. I think I did answer part
of the question, and referred the user to a vendor-specific help
channel for implementation specific details.

A terminology observation:

We sometimes say "SenderID" when we mean spf2.0, and that includes of
course "mfrom", to some degree (99%) the same as v=spf1, reserving 1%
for positional modifiers (all hypothetical, as it was in summer 2004).

We sometimes say "SenderID" when we mean spf2.0/pra (+ ESMTP SUBMIT),
that doesn't include "mfrom". The fate of spf2.0/helo is unclear, I'd
claim that it's an integral part of spf2.0/mfrom or v=spf1, certainly
not a part of "SenderID".
