Re: [mlmmj] mlmmj and spf

[theo borm <theo_mlmmj@borm.org>]

Thanks

I already contacted the organization and they replied: your server is 
not under our control, so therefore we will not put it in our SPF 
records (...). Check of the actual spf records reveals that microsoft, 2 
/16 subnets, a few ISPs and a couple of others are already in there. 
Must be a very powerful organization to control all these.

Mlmmj as-is doesn't appear to have a way to *rewrite* headers. I can 
delete and insert headers no problem, but nothing in the way of 
rewriting or variable substitution on headers.

I just had a look at the sources. Hacking support for this into 
mlmmj-process.c/do_all_the_voodoo_here.c looks doable.
