Thanks Bill and Mike,
As user zimbra I did:
Code:
zmprov -l ms mail.centrex.com zimbraPop3BindPort 110 zimbraPop3SSLBindPort 995 zimbraPop3ProxyBindPort 7110 zimbraPop3SSLProxyBindPort 7995 zimbraImapBindPort 143 zimbraImapSSLBindPort 993 zimbraImapProxyBindPort 7143 zimbraImapSSLProxyBindPort 7993
all on one line, then as user root I did
Code:
service zimbra restart
Now the services are listening on the correct ports.
imapproxy is no longer showing in the server status page and Thunderbird can retrieve and handle messages again!
I wish I could rename the thread title as it really seems to have been purely an issue with incorrect use of imapproxy, nothing directly related to Thunderbird.
Hopefully other people who are affected by this will find this thread anyway.
Thanks again!
