Take the '=' sign out of the code line. so line should read. Thanks for the quick fix. I also ran into the same issue with IMAP and clear text login. Second code line addresses that.

Code:
zmprov ms zcs.server.name zimbraReverseProxyPop3StartTlsMode on

zmprov ms zcs.server.name zimbraReverseProxyImapStartTlsMode on
