Good day!  E-Mail security and spam prevention is becoming more relevant as
approximately 53.5% of all e-mail traffic worldwide is spam.  There's been
numerous enhancements made to e-mail including Sender Policy Framework (SPF),
Domain-based Message Authentication, Reporting, and Conformance (DMARC), and
DomainKeys Identified Mail (DKIM).  Currently, and from everything I've
reviewed, Synchronet has no ability to embed DKIM header information into
outbound e-mail.

The advantage of DKIM is the outbound message is signed with a private key.
With the combination of the signed message and the DNS record selector
(allowing multiple subdomains to coexist), the message is effectively validated
from source.  When the receiver reviews the header and inspects the public DNS
record, the message is validated.

More information can be found at dkim.org.  Within Synchronet, I'd like the
ability to embed DKIM into the outbound message header.  The creation of the
certificates (public/private) should remain in the hands of the individual
SysOp (OpenSSL, Cygwin, PuttyGen, etc.) but the private key location and the
hashing of the message (and placement into the header) should become a function
of the Internet E-Mail module.

What do you think?
