If you have the proxy running then you can disable it with the following:
Code:
zmproxyctl stop
zmprov ms server.domain.com -zimbraServiceEnabled imapproxy
zmcontrol stop
zmcontrol start
You should also reset the ports with this (all on one line):
Code:
zmprov -l ms server.domain.com zimbraPop3BindPort 110 zimbraPop3SSLBindPort 995 zimbraPop3ProxyBindPort 7110 zimbraPop3SSLProxyBindPort 7995 zimbraImapBindPort 143 zimbraImapSSLBindPort 993 zimbraImapProxyBindPort 7143 zimbraImapSSLProxyBindPort 7993
Then stop/start zimbra or reboot the server and see what happens then.
