I was wondering if there is a way to get WordPress to encrypt notification mails (“Please moderate …” and so on) using PGP.
I have found a bunch of plugins providing PGP-encrypted eMail forms, but that’s not what I was looking for, as I want the system mails to be encrypted, not the user mails.
Is there any plugin or modification that does this that I have not found?

There’s a small PGP plugin by Tim Nash on GitHub (but it’s not in the official WordPress repository, it needs to be manually copied to wordpress plugin directory). It’s a wrapper using php-pgp library for encryption. The article where I found this link is “Encrypting emails with PGP and WordPress”. This is the only WordPress solution I have found so far.
I was also digging into the subject and I’m trying more generic approach – extending PHPMailer to support PGP encryption. However, this requires some more testing to support email in both text and html format, PGP/MIME, attachments etc. so this is not ready to be published yet.
