I'm running zcs-4.5.10_GA_1575.UBUNTU6 in a VM, with host and guest OS Ubuntu 6.06 LTS. The idea was to check out ZCS in a controlled environment. However, after several months of successful usage, now I can't get anything through.
zmcontrol stop shuts down everything except antispam. It seems unable to stop antispam.
zmcontrol start shows everything running.
top shows amavisd bouncing between 80 and 99%
All I've done to modify the original setup was to add rbl's to zimbraMtaRestriction per the Zimbra Wiki, and that was several weeks ago. Things stopped working a few days ago. Can anyone tell me where to begin?
