    Hello

    Could someone tell me if the cpanel already corrected this bug, and if so where can I find this fix thanks

    Bug 667
    Summary: Dovecot authentication bug - missing close

    I'm using SMTP auth with Exim authenticating against Dovecot's auth
    socket. The (excellent) SMTP test tool "swaks"
    (www.jetmore.org) tries multiple auth mechanismus
    consecutively which leads to the following message in Dovecot's log
    file:

    Error: auth(default): BUG: Authentication client gave a PID 6738 of
    existing connection


    This bug can be fixed by adding a "close(fd);" in src/auths/dovecot.c.
    Without the close()-call Exim does not shut down the connection and a
    subsequent connection (announcing the same client PID during
    handshake) will fail. You'll most likely see the above warning message
    if a SMTP client tries multiple auth mechanisms with a wrong password.

    Would be nice to have this fixed upstream in the Exim source.

    source: bad link

    All cpanel published versions of Exim are currently at 4.69:29, which should have this patch included.
