    Hey guys, anyone ever received an error like this when sending to an ISPConfig mail server? My gmail account keeps returning these when I send to one specific account. Other addresses on the server seem to work ok. As far as I can tell

    Technical details of temporary failure:
    TEMP_FAILURE: Could not initiate SMTP conversation with any hosts:
    [xx.xx.xx.xx. (10): Destination address required]

    What's in the mail log on the ISPConfig server?

    The messages don't even show up in the logs. It must be an issue with gmail not being able to connect to my smtp server. Works fine from other smpt servers. From doing some research, it looks like people have similar problems with not being able to connect over port 25, such as ISP blocking port or something. I'll have to look into it some more.

    Please check that your MX record points to the correct server, that your firewall doesn't block port 25, and that your ISP doesn't block port 25.
