Feature Request - DKIM and DMARC Support

As many spam filtering providers are continually upping their defenses against spam, DKIM and DMARC support is going to be an increasing need-to-have for authenticating client's email servers as non-spammers.

Rackspace is even updating their systems to support DKIM signing on outgoing email and will be implementing DMARC as well which is going to make spam filtering even more troublesome with them when our client's systems don't support either.

And Office 365 supports DKIM as well...it seems rather odd that Reflexion is lagging behind so much in bringing these features to the table.
