Central Email Gateway Outbound Policies and DKIM record

Deepak Verma

Dear All,

I know that Sophos Central Email Gateway is providing Inbound security But What about outbound mail securities If Sophos is configured for outbound too. How to configure any policies for outbound?

We need a DKIM signature (record).  How does Will get from Sophos Central mail Gateway.

  • Outbound does not support DKIM right now. Only SPF (because it relies on the DNS record).

    https://community.sophos.com/kb/en-us/132343

    Central will simply use the same mailboxes for outbound like inbound. Is there a mailbox - Central will accept the mail outbound. 

     

    DKIM / DMARC and the other Spam checks are only supported for inbound (Central scans the inbound mails).

    Outbound should be used to keep matching MX Records etc.

    Hi,

    One more question:

    I will configure an SPF record with the same value for all my domains which are configured for outgoing mail? will this value change based on a domain name?

    v=spf1 include:_spf.prod.hydra.sophos.com ~all

     

    There is no changes (per domain name based).

    Hi Deepak That record would be accurate as long as all of your domains are routed outbound via Sophos Central Email and you are sure that no other 3rd parties send mail from those domains on your behalf You could also narrow this down further to the specific Central region if you wanted, using the information in community.sophos.com/.../132343 Greg
