Possibly state retention but I don't believe that the check_command is
ignored with state retention enabled. I know I've seen specific
documentation that tells exactly what is important wrt retention but I
haven't been able to locate it on short notice.

I'm going to bet that your its-host template contains the check_command
of check-host-alive and that's why smtp3 works (it's inherited). For
imap1, since you are using the same template it should also inherit the
check_command defined in its-host, _however_ the fact that you've
defined a check_command within the host definition itself overrides any
previously inherited definitions. What is the exact error that you're
seeing for this host that makes you think it's not working?
