It still seems strange to me that anybody has ever bothered with using OCR
to deal with image spam, when it's so easy, and for me not problematic, to
just block all emails that might be image spam - those with an attached
image that is embedded in the body of an html mail.

In my postfix main.cf I have:
body_checks = pcre:/etc/postfix/body_checks
And that file just contains:
/\bsrc\s*=(?:3D)?\s*["']?cid:/ REJECT Your email was rejected because you embedded an attached
image in the body.

So if somebody ever sends me a legit email with an inlined attached image,
they'll still get an error, without me causing any backscatter.

My mom was annoyed that she couldn't use some tool to decorate her emails
to me with garbage, but... that doesn't qualify as a negative for me.

I've been very happily using this since 2006, and it completely made image
spam go away.

People can still send me images attached to emails, and they can still send
me emails with images embedded in the body of html emails as long as they're
hosted on a web server and not attached.  It only gets rejected if the
image is attached *and* embedded in the body of the email.

Inlined attached images are not a feature that I find anywhere near worth
having enough to justify needing to OCR image spam.
