I'm looking for an smtp service that essentially obeys the RFC, except rather than sending mail it simply logs to a file
[date] sent mail to <address>
Or whatever. I can bash this together with the bare minimum of functionality I need in python in about half an hour I reckon but if there's an existing project that works better I'd rather use that.
The reason for needing it is debugging an app that keeps sending 7* the amount of mail it's supposed to.
Slightly offtopic, but if there isn't already such a project, and I write it, is this something other people would use? If I publish the source will it get used?
