I'm new to Zimbra and was attached to the quality of the product. I've been using Postfix in the past with Squirrelmail. I've installed the latest version of Zimbra and I have everything setup including the masquerading (@domain.com instead of @mail.domain.com) on sending but I can't seem to receive mail. If I send a test mail from yahoo to @mail.domain.com, no mail comes through but I don't get an error on the yahoo side for a failure. If I send to the masquerade address (@domain.com), I get a failure error on the on the yahoo side immediately. Either way, no mail is received on my server. I'm sure it's something very simple I'm missing.
Any help would be appreciate. Thanks in advance.
