    I set up ispconfig on a new host and am trying to send and receive emails through an smtp gateway. I use MailCleaner as a gateway, I register the domain and sending is ok after informing the relay smtp. However when I send emails to this domain MailCleaner cannot validate the callout and always returns with the error mentioned:

    Remote server replied: 550-Callout verification failed:
    550 550 Delivery is not allowed to this address.

    Forgot something disabled?
    How to get around this and make validation work?

    You should ask the mailcleaner support to help you debug the problem with their gateway.

    Hi till
    I use it with ZImbra, Hmailserver and 4 more Linux based mailservers, and it works without problems.
    Would I need some additional adjustment to the configuration files before I can receive mail forwarded by the gateway?
