[BlueOnyx:23322] Sendmail failing

[Colin Jack]

Good afternoon,

I have a 5209R which has suddenly got the rats with sendmail.
It keeps stopping after a few minutes.
If I try and start from the CLI (/systemctl start sendmail.service) it fails with

Can't open PID file /var/run/sendmail.pid (yet?) after start: Too many levels of symbolic links

If I reboot the server or disable/enable smtp from the GUI it starts but stops after a few minutes.

Any thoughts / suggestions?

Thanks

Colin
