Do I need MX record for only sending emails?

Hello,

The process of setting up a custom MAIL FROM domain requires you to add records to the DNS configuration for the domain. You have to publish an MX record so that your domain can receive the bounce and complaint notifications that email providers send you.

You also have to publish an SPF (type TXT) record in order to prove that Amazon SES is authorized to send email from your domain.

Also, keep in mind that, To successfully set up a custom MAIL FROM domain with Amazon SES, you must publish exactly one MX record to the DNS server of your MAIL FROM domain. If the MAIL FROM domain has multiple MX records, the custom MAIL FROM setup with Amazon SES will fail.

Hello,

The purpose of an MX record is to route emails to a mail server using the Simple Mail Transfer Protocol (SMTP). It's what tells resolving name servers where your domain “mailbox” is, and without it, you wouldn't get your emails.

In order for an MX record to function correctly, it must point to an A or AAAA record. It is a configuration that specifies which mail servers can accept email that's sent to your domain.

A CNAME record is used for referencing a domain's alias instead of its actual name. CNAME records typically point to an A record (in IPv4) or AAAA record (in IPv6) for that domain. However, as mentioned MX records have to point directly to a server's A record or AAAA record.

Hope that helps !!

Same problem,

Basicly, if i use another hosting for receiving email i wont receive some of my email if i set another MX record or they both receive it?. When first setting up SES this was not needed. I first setup SES no mx, then moved in to AWS Workmail and added MX for that now moved out from Workmail and received an email telling i have 3 days to put an mx record.
