I have been setting up our E-Mail sending in the last few days including SPF and Sender-ID authentification. What I am missing still is DKIM.
Here is my situation:
I am using IIS 6.0 on an windows 2003 server und generate the mails with UTL_SMTP in ORACLE.
I tried to write the DKIM signature directly into the mail header but I am missing the Body Hash. To my understanding the body hash is simply a hash over the message body. Am I right? How can I compute this Body Hash in Oracle depending on the message content? Also what about HTML mails. How do I get the Body Hash for that occasion? Do I even need one?
