nullmailer is also a solution for this case where running a full mail server is an unnecessary complication. However, it doesn’t seem like this supports queuing which I think is a requirement for real SMTP support.

Daaamn, this would have been great when we were trying to resurrect some ancient MFDs. We ended up ditching Scan to Email completely and moving to our FTP. Cheers OP, I'll keep this in mind.

You could also have used stunnel, which is the generic program for proxying in/out of TLS connections (might not work with starttls, though).

FWIW, requiring encryption on a public MX host is a violation of RFC, if memory serves.

Where do I find documentation for installing stunnel on a proprietary printer/scanner/copier? :-)

Can't you just do this with Postfix and the 'relayhost' setting?

Step 1) attach lowpower Linux board of your choice

Step 2) install stunnel on it

:D

And exim with a smarthost configuration. But if you already have Python, this might be simpler to install and configure.

Is there a POP or IMAP server for jailbroken iOS?

I tried installing Dovecot from here, but it put my iPhone into a boot loop (try it at your own risk!).

http://ios-webstack.tk

The reason I want it is so that I can distribute arbitrary files to other iPhones using a local WiFi network without sending data to a cloud sharing service. For example, a mixtape of MP3 files, or a photo album.
