You should look at this wiki - https://wiki.zimbra.com/wiki/Saslauth_F ... orm_error), and look and see if you have an error in /var/log/zimbra.log at that same time. Oddly though this seems like an error simply trying to reach the lookup service, but that can happen if there is some other proxy - so do the exercises in the Wiki article. That article is referring to a case where there is a separate Zimbra MTA server and separate mailstore, but that might be the case for you if you are running "all-in-one" (all services on one server).
