Solution for Anti-spamming on SBS server 2003 RRS feed

  • Question

  • Hi All,

    We have an issue with Anti-spamming by IP Address by anti-spamming organisations (e.g. Google etc)

    I have a SBS 2003 with Exchange 2003 SP2.

    Internet connection = ADSL dynamic IP.

    Local domain = abcd.local

    3 Email domains = tom.com; dick.com & harry.com - connected via POP3 Connector for incoming emails and relayed to a Smart Host (my isp's) smtp.myisp.com

    Since I'm using 3 different email domains, there is no authentication for the relaying. Therefore, all email headers shows as "abcd.local" which is an invalid FQDN.

    About 98% of operations, everything is fine. Once in a while, I get blocked by these Anti-spamming guys. Does anyone has had similar experiences, solutions or recommendations?

    thx,

    SN

  • There are lots of thing you can do here.

    1 - Change the Full Qualified Domain Name on the virtual SMTP adapter.

    To do this: in Exchange System Manager navigate to the Server.

    Open Protocol and click on SMTP.

    Right click on Default SMTP Virtual Server and select properties.

    Under Delivery tab click the advanced button.

    Change the Fully Qualified Domain Name to a valid Domain.

    2- You could add a SPF record to the domains, the correct SPF will need to be research due to your configuration.
