For posterity, here's the issue I encountered, in case anybody comes across it:
1. User forwards an email from RoundCube. It has attachments as .eml files. The forward appears to be successful, with the Sent message stored in the respective folder.
2. Exim never actually delivers the forward, and never triggers a bounce, with only the trace of an issue being a log entry: "discarded (system filter)"
This experience led me to /etc/system_filter.exim, a collection of filters that seem to have a history as far back as the ILOVEYOU worm. The filter has '.eml' defined as a regular expression match.
So my question is (perhaps to DirectAdmin staff as well): do these system filters still serve a purpose and should DirectAdmin include them in the default configuration? and if so, should the .eml value from the regular expression be stripped by custombuild?
I know why there's no bounce, as the worm would probably generate an incredible volume of them, but exim quietly eating emails doesn't inspire confidence.
