IMAP Problems

[rusty]

It is a single server and I did use a lower case i\

[zimbra@mailhost root]$ zmprov gs mailhost.domain.com | grep Imap
zimbraImapBindOnStartup: TRUE
zimbraImapBindPort: 7143
zimbraImapCleartextLoginEnabled: TRUE
zimbraImapNumThreads: 200
zimbraImapProxyBindPort: 143
zimbraImapSSLBindOnStartup: TRUE
zimbraImapSSLBindPort: 7993
zimbraImapSSLProxyBindPort: 993
zimbraImapSSLServerEnabled: TRUE
zimbraImapSaslGssapiEnabled: FALSE
zimbraImapServerEnabled: TRUE
zimbraReverseProxyImapSaslGssapiEnabled: FALSE
zimbraReverseProxyImapStartTlsMode: only
[zimbra@mailhost root]$

[rusty]

zimbraImapCleartextLoginEnabled: TRUE

I may have changed this value troubleshooting.

If it's a single server you shouldn't need the imap/pop proxy unless you're doing something else custom:

zmprov ms server.domain.com -zimbraServiceEnabled imapproxy
zmprov ms server.domain.com -zimbraServiceInstalled imapproxy

Run the following all on one line:

zmprov -l ms server.domain.com zimbraPop3BindPort 110 zimbraPop3SSLBindPort 995 zimbraPop3ProxyBindPort 7110 zimbraPop3SSLProxyBindPort 7995 zimbraImapBindPort 143 zimbraImapSSLBindPort 993 zimbraImapProxyBindPort 7143 zimbraImapSSLProxyBindPort 7993

Your putting a 7 in front of anything with proxy in it & correcting the ports (lowercase ell L at the front provisions via LDAP).

Then:
zmcontrol stop
zmcontrol start

Notice the minus infront of -zimbraServiceEnabled, that way you can just remove one service. If you weren't to use the minus (or plus) you'd have to specify all the services desired. Just a warning because I don't want you to forget the minus and just set your box to nothing but imapproxy on accident.

I followed your instructions exactly except inserted actual server name

zmprov gs mailhost.domain.com | grep imap > now shows no output.

imapproxy began running (was installed) when i first upgraded to 5.0.2, but I never knew it shouldn't be running. Don't know why it decided to be a problem once I upgraded to 5.0.5.

IMAP seems to be running now, thanks.

I mentioned clear text login was enabled. I'd prefer it was disabled for greater security. Do you know what the Zimbra default is? Are you aware of any repercussions from disabling it? I believe all my clients are connecting via SSL/TLS.

zmprov ms server.domain.com zimbraImapCleartextLoginEnabled FALSE

It seems to only affect certain accounts, and it is cleared up, at least temporarily, by running 'zmmailboxdctl restart'. I'd like to find out what's causing this so I can prevent it from happening.

Let's get some more info in mailbox.log:
zmprov aal user@domain.com zimbra.imap debug

This can be turned off by 'ral' or it's removed automatically on next server restart.

If you want to do it across the board for everyone you can modify /opt/zimbra/conf/log4j.properties.in and append:

logger.com.zimbra.imap=DEBUG

Levels are FATAL, ERROR, WARN, INFO, DEBUG; see this section of the NE Guide.

The fact that your 5.0.4 and ubuntu reminds me of this thread: [SOLVED] Too many open files error after increasing zimbra_session_limit_imap (ulimits were increased for 5.0.5)
