When I run the command you listed via cron, it doesn't seem to do anything with amavisd. Nothing shows up in /var/log/zimbra.log about it starting up like it does when I run the command manually in a terminal.
So, to that end, I put it on a separate line, and just had it sleep a bit before running (to give the sa-update time to finish).
Here's what I get now:
Code:
Stopping amavisd... done.
Starting amavisd...failed.
Indeed, all messages after that get deferred into the queue, and I must run 'zmamavisdctl restart' manually to kick it back online. Any ideas?
