[nylug-workshop] smtplib and domainkeys, mangling headers?

[Michael Dizon]

Hi Guys -- I have a question regarding Python's smtplib. I've
successfully implemented DomainKeys with sendmail on my server, I've
tested it by sending mail from one of the applications available on my
server's management console.

However, when sending mail from my application, the DomainKey is
included in the header, but fails to authenticate when received.

I've attached a sample of both e-mails below.  Note the
"Authentication-Results" header
