I have multiple zimbra accounts which I have set up as external accounts on my main email. This allows me to pull email from all my accounts with just the one login. I use POP3 to access these accounts. One of them, (5 others continue to work without issue), began failing last night with this error:

account "CPWConnect" Failed
--------------------------------------------------------------------------------
system failure: Unable to connect to POP3 server: DataSource: { id=595556fc-6c87-4313-b97d-f9747d95a9a0, type=pop3, isEnabled=false, name=CPWConnect, host=mydomain.com, port=995, connectionType=ssl, username=CPWConnect, folderId=1014 }, Invalid STAT response: 113631 2166837977


[zimbra@zimbra ~]$ zmcontrol -v

Release 6.0.7_GA_2473.RHEL5_20100616214455 CentOS5 FOSS edition.



I see the following in my mailbox.log file:
