Following was told me in IRC:

16:00 -!- Irssi: Starting query in Freenode with nick omitted
16:00 <nick omitted> hi, are you working on cups-mailto? :)
16:01 <nick omitted> in its current state it's impossible to get it to work with os x el capitan and newer
16:02 <nick omitted> because they took away the sandbox: off option in cups-files.conf
16:03 <nick omitted> i'm not an os x user myself though, so it's a bit difficult to debug

The MTA seemingly cannot read the spool file on some systems, like Fedora, or as I have heard, OS X El Capitan and newer. That is because security measures like SELinux (in Fedora's case) and the sandboxing system in OS X/macOS.

Possible solution: take the input as STDIN instead of spool file.

Curretly this driver gets the to and from addresses from manually defined lpoptions mailfrom and mailto. This is however not a very good user experience. Starting from CUPS 1.3, it has been possible to have PPD files accept arbitary strings as configuration options, but the syntax is confusing to me.

Another option would be to have a separate configuration file like CUPS-PDF has, but that would again be inferior to the former option in what it comes to user experience.

On Fedora, SELinux is preventing esmtp from read access on the file /var/spool/cups/tmp/.esmtp_queue/

Possible fix: Use smtp instead of sendmail command.
