Hello bcw142!

Ah! How do you start MIS? I use a systemd service for mine, so it knows if has already been started. I also let it call 'mis poll killbusy app' on startup, which will remove semaphore files such as mutil.bsy, which can otherwise stop any mail from being processed (at least for a certain amount of time).

I run two external programs (binkd and ifcico) for the actual mail transfers; otherwise I would let it call 'mis poll killbusy all' instead on startup, which would clear also any busy (.bsy) files in the outbound directories for outgoing calls (which would otherwise stop any polls from happening, at least for a certain amount of time).

In case anyone would be interested, here's a sample /etc/systemd/system/mis.service file (pardon any strange line breaks, and adjust paths and user/group as needed):
