    Default Zimbra OSS 8.0.5 :: Proxy issues

    Hi All¡¡

    we have multi-server installation with 4 Mailboxd server all of them with POP3/IMAP access ( no webmail )
    All its ok until i enable pop3/imap proxy on any server.

    When user login with clear text password POP3 on proxy, login its successfully and small mails are downloaded without problems, but random user experiment:

    nginx logs:
    SSL_read() failed (SSL: error:1408F10B:SSL routines:SSL3_GET_RECORD:wrong version number) while proxying and reading from upstream,
    SSL_read() failed (SSL: error:1408F119:SSL routines:SSL3_GET_RECORD:decryption failed or bad record mac) while proxying and reading from upstream,

    This logged error cause pop3 session down.

    Any Idea?
    I dont understand SSL Erros on non SSL pop3 Session.

    The first thing you should do is upgrade your servers ASAP for this reason. If you still have the problem after the upgrade then take a look at some of these threads. FWIW, I'd suggest your users should be using a secure connect for connecting to your servers as anything else is a security risk.

    Is it ok for you to try dissabling secure interprocess comunications? This is actually a Zimbra recomendation extracted from tunning guides.

    zmlocalconfig -e zimbra_require_interprocess_security=0

    As this is a server configuration, make sure you apply it on every server.

    Hope this helps,
