DomainKeys Identified Message (DKIM) on shared host.

[rbellamy]

I am trying work through problems delivering mail to Yahoo!. DKIM seems like the most appropriate solution, however the site is running on a shared host, and the ISP does not offer DKIM.

Consequently, it strikes me that a solution would be to insert the appropriate header at message creation.

I have yet to find an implementation written in PHP.

Any suggestions?

DKIM is more than just PHP - you have to add a DNS record, then "sign" a message as it goes out.
