    Default network_biopair_interop

    We upgraded to 5.0.25 in December. Since the upgrade I am seeing a LOT of the following errors in my /var/log/mail.warn logs.

    Feb 9 01:38:15 newman postfix/smtpd[24043]: warning: network_biopair_interop: error reading 5 bytes from the network: Connection reset by peer

    I've tried following links on the Zimbra site to Postfix, and we have not recently renewed our license or modified TLS, or any of the other responses that I've found regarding this problem. Is there an issue with this upgrade? I'm not sure what to do to rectify this problem.

    The short version is,

    Don't worry about it.

    the far side didn't negotiate the tls connection correctly, and dropped the connection.

    This isn't a fail,
    it's a warn.

    I spent a lot of time learning the long version of this a few years back
    but in the final analysis, it was just move along, nothing to see here.

    Hope this helps.
