    Sup folks,
    I am receiving the following errors from postfix which results in an email every 10 minutes. Does anyone know what smtpd restriction would be causing this error?

    This is the error:
    Code:
    Dec 10 02:17:51 www postfix/smtp/smtpd[8709]: connect from m139.em.secureserver.net[198.71.245.11]

    That makes me suspect there is a typo in some postfix configuration file. Maybe search for "OK" or "restriction" in /etc/postfix/*.
    Are these incoming or outgoing e-mails? Is m139.em.secureserver.net your server or some random host from the Interwebs?

    Thanks Taleman. From my understanding, and I could most definitely be wrong, m139.em.secureserver.net would be the server that GoDaddy uses for thier bounced emails. Not sure if they are incoming or outgoing. I did receive these errors before but I just ignored them, now their just getting annoying. The subject of the email reads:
    Which makes me wonder if its an error on their side. I only get the errors when ther is a GoDaddy bounce message.
    I will do a little digging to see what I can find with "OK" and restriction and get back to you.
    Thanks.

    I was able to resolve this issue with Taleman's guidance... much thanks.
    For anyone who runs into this issue you can solve it by adding a whitelist record in postfix. To do so...
    1. Login to ispconfig
    2. Navigate to Email > Postfix Whitelist (under global filters)
    3. Add a new record with sender as the type and the domain in the whitelist address. (In my case it was bounces.em.godaddy.com)
