I have a filter configured to send notifications for certain events, and I know it is working correctly because I see zmfilter log "Creating notification message". However, unlike I have in previous setups, I'm not seeing a second "Sending notification message" line. I have postfix installed and working through the mail command. There is no other log output from zmfilter when this happens.

What could be happening after creating the message that prevents it from sending? Is this a known bug? I was running 1.30 on Ubuntu before and it was working with SSMTP, but that version isn't available in the Debian repo (yet?). Thank you for any suggestions.
