    I have configured an e-mail account in ISPConfig3. It sends e-mail no problem but When I send to it from outside, e-mail grom my gmail account bounces with the following error:
    But when I send e-mail from my exchange server, it comes through with no problems.

    I looked in the /var/log/mail.log file but it did not show any activity from gmail that I could see.

    Check the dns records for the domain "" if all MX records are pointing to the correct server.

    Got it

    I checked the DNS and it was all OK BUT when I did an external port scan for the domain, it became evident that the firewall was porting all incoming e-mail traffic from our multiple IP addresses to a different server. Sending e-mail from that server to the ISPConfig server worked OK but outside e-mail servers could not find the ISPConfig Server.

    Got it fixed.
