[dkim-ops] DKIM + Qmail

[Charles Sprickman]

Hello all,

I'm having some issues tracking down a current implementation of DKIM 
signing for qmail.  We run some rather large lists and we do modify each 
message after it has hit the queue to include subscription information in 
the body.  This means that we're left with having to sign the email 
further down the chain in the qmail-remote process.

There is one patch floating around out there for qmail-remote:

http://test.frob.com.au/qmail/patches/qmail-1.03-remote-verh-dk.patch

I'm still not entirely clear on whether the libdomainkeys and 
libdk(milter) are even compatible.

We'd love to "upgrade" from SPF to DKIM and just skip DK, but I'm just not 
finding any solid info for Qmail.

Any pointers?  Any major players (besides Yahoo) running qmail and very 
large lists?

Thanks,

Charles
