  • Problem With Exchange Configuration On my SBS 2000

    I have an SBS 2000

    Recently I changed the A records from my isp (and so pop3 mailboxes) to my fixed IP of our organisation exchange server.
    Everything looks fine until, for a reason i don't understand, i received to some sent e-mails (not all e-mails) the following error message:

    [email protected]' on 01/12/2006 11:33
    You do not have permission to send to this recipient. For assistance, contact your system administrator.
    <mydomain.co.il #5.7.1 smtp;501 5.7.1 <[email protected]>... Sender IP must resolve>


    What did i do wrong?

    Thank you all in advance for your answers.

    I think the clue is in the "Sender IP Must resolve"... I am guessing because I have no Exchange experience to speak of - but:

    Does your mail server have an MX record in DNS?

    Is your external mail sending relay or server in "public" (internet) DNS?

      Thank Stonelaughter for your fast reply... appreciate.

      My MX record (and not my A records, as i wrongly mentionned before) has been redirect to my exchange server, that's a fact. when i ping mail.mydomain.com
      i received my ip replying.

      It may be a wrong dns configuration but i don't really know what should i do?

        I am not sure based on your explanation who is sending what from where, but f you do not not add your domin e-mail address to the rules in the default recipient policy, you will get an error like this trying to send to someone from outside the organization.

          i've added the domain (the internet domain) in the recipient policies, made it Primary. but still when some user inside the network are sending to some domains (not all domains), they receive the error shown above.

            Sounds like you may not have a ReverseDNS record which, in order to try to cut down spam, many mail servers will not receive from today.
            Look up your domain in www.dnsreport.com especially for the mail (MX) section.
            TIA

                For the record, ReverseDNS=PTR
                TIA
