Hi, I am currently working at an implementation of DMARC support in a Perl module. My guess for the name would be Mail::DMARC (as Mail::DKIM provides support for DKIM). Module will provide an XS wrapper for libopendmarc from opendmarc.org, (my approach would be to package a Mail::DMARC::libopendmarc module used my Mail::DMARC with some configuration switch) and possibly an alternate pure Perl implementation not requiring libopendmarc (which might be embedded in the Mail::DMARC module itself or with a Mail::DMARC::pure separated module).
It's been a long time since I last worked on a module as an author, so any comments on naming or - for that matter - anything else will be grealy appreciated. Thanks, Davide
