DKIM - DomainKeys Identified Mail
After reading a lot of your ideas last year I was looking to implement DomainKeys on one of my servers. However I found it very difficult because none of the big mail transfer agents like Exim or Sendmail even had plug-ins available. I'm still not sure whether there are many release candidate level implementations out yet. I put my project on a back burner to wait until the software options became available.
Is there anything the average webmaster can implement on his server today other than SPF?
