Hello
I've understood that EFA server receive mail before mail server. But what server should match the MX record : EFA or mail server ?
If the mail server should match the MX record how can I redirect mails to EFA server ?
Regards
EFA topology
Re: EFA topology
Set mx record to EFA, and then you set mail server in EFA in EFA console.
Re: EFA topology
Your MX records should point to the EFA server. The idea is that your mail server will accept incoming SMTP traffic only from the EFA server. As far remote mail servers are concerns, your EFA server is your mail server. Here's a very general overview of the topology:
1. Remote server looks up your MX records and sends smtp message to the lowest-numbered available server
2. The traffic hits your firewall and router, which forwards the public IP smtp port to your EFA server
3. The EFA server processes your message and takes appropriate actions (discard, tag, relay, etc.)
4. The EFA server relays acceptable messages to your user-facing mail server.
Users should continue to access your current mail server as usual. The only difference is that you have added a relay host (EFA) between the public internet and your mail server.
