    Default ZWC can't configure external IMAP account


    I'm trying to access an external IMAP account through ZWC but it is not working.

    I enter all the parameters correctly and when I click on "Test Settings" I get the following error:

    "Error: * BYE JavaMail Exception: Socket closed"

    I traced the connection between Zimbra and the external server and could see that although I didn't ask for SSL, Zimbra attempts a STARTTLS command. I guess it doesn't like the server's self-signed certificate and I can't find where I should put the certificate on the Zimbra server.


    Zimbra server 5.0.23 X64 on Linux Redhat Enterprise Server 5.3 X64.

    Default IMAP Cert

    Trying to connect to an IMAP host with self-signed cert and it complains about a mismatch and won't allow it to be added.

    I found this on another post:

    zmlocalconfig -e 'data_source_trust_self_signed_certs=true'
    and or
    zmlocalconfig -e javamail_imap_enable_starttls=false

    restart mailboxd

    Second one worked for me.
