    Is it probably a smarthost mail verification problem?

    @ it shows

    "SMTP Reverse DNS Mismatch Warning - Reverse DNS does not match SMTP Banner"

    don't know how to fix that with ispconfig & multiple vhosts

    kind regards

    Ensure that the reverse dns record of your IP address is the hostname of the server. It does not matter how many websites you host on this server as the hostname of the server exists only once on each server and this is not ispconfig specific.

    I would do that if I could

    my provider sets the reverse dns name bound with the modem, it looks like:

    do you see any chance to override the reverse dns name?

    best regards + thanks a lot

    You must ask your provider.
