IMAP parse error: command not implemented

[danfluidmind]

I'm switching my users over from a CyrusIMAP server to a Zimbra server. Last night I transfered one of the users and changed her Thunderbird settings to point to the new server. After pointing it to the new server, Thunderbird gave me the following error, over and over again:

"The current command did not succeed. The mail server responded: parse error: command not implemented"

Not very useful, since it doesn't have the decency to tell me what command did not succeed. I assume it was trying to do some IMAP command that it had been using with the Cyrus server, but the Zimbra IMAP server doesn't understand it.

Anyone have any idea what that might be? What Zimbra log file might I look it to see if it logged the offending command?

Thanks

Check in mailbox.log. (If it's not there, you may want to enable verbose IMAP logging for a brief period while you figure this problem out.) Thunderbird may also have a logfile.

I looked in mailbox.log and saw where I started making the connections with Thunderbird after the transfer with imapsync. Couldn't see anything about the errors. Where do I go to turn on verbose IMAP logging?

Removing the IMAP account from Thunderbird and re-creating it fixed the problem. Still, I'd like to know what IMAP features Thunderbird had been using with Cyrus that Zimbra doesn't seem to support.

In /opt/zimbra/conf/log4j.properties, add a line like this:

log4j.logger.zimbra.imap=DEBUG
