| Hello Mike,
You are absolutely correct about mail servers and clients that communicate over SSL. But for mail servers and clients that do not communicate over SSL how can we intercept the email at the NKE level / listener / filter and modify it as desired. Is this feasible ?

If I want to get access to emails at the kernel extension level then what type of NKE should I write and is there any
documentation or sample code to help me get started. Basically I want to filter out/modify emails based on some conditions irrespective of the email client. Any help would be appreciated.

The short and simple answer is that this is not possible with any degree of generality. A large proportion of email traffic is transacted between the email reading application and the servers it uses over SSL. The en/decryption for SSL is handled by libraries called directly by the application itself, so by the time you would see the email in the kernel, it will already have been
encrypted.
If you want to mess with someone's email you need to be the server their MUA is talking to.
