    Default Canīt delivery some mail..

    Why some servers donīt want to receve the mail from my server?

    I got the "delivery temporarly suspended: server_xx refused to talk with me:544"

    Is your ZCS server on a public/private IP ? Do you have a valid rDNS entry for your server ?

    So does the rDNS entry match the name of your Zimbra server ? If not then you would be better using your upstream ISP SMTP relay server to send external email.
