What signals a termination for smtpd filters? I'm using the code at https://github.com/Beutlin/howto-opensmtpd-filters-and-reports, Which works great, except for when smtpd gets shutdown. The script continues to run and consumes up to 100% cpu time, while keeping the smtpd parent? process running.
I've tried adding a SIGTERM handler to the code which didn't work, as well as I saw mentioned that the filter should exit on EOF, so I tried wrapping parser.dispatch() in a try/except EOFError and using sys.exit. That didn't work either. I've read smtpd-filters, and looked at various other filters and I am not understanding what tells the filter to shutdown. Regards, -Andrew
