It seems adding a TXT entry in DNS about Google is a good practice (when using gmail to send mail) to prevent being considered as Spammer. So I could add a TXT entry in my DNS records to:
example.org TXT "v=spf1 include:_spf.google.com ~all"
But, this domain is also used to send mail via Amazon SES (I work for a web company that send mail via a web application). In other words, mails are sent from
email@example.com via Gmail and from
firstname.lastname@example.org via Amazon SES. In order to avoid being considered as a spammer, should I:
- Do not add a TXT entry about SPS at all.
- Add a TXT entry for google "v=spf1 include:_spf.google.com ~all"
- Build something for both Amazon and Google (but I don't know what).
- Something else?
Side note: MX entry for google (
aspmx.l.google.com, etc.) and TXT for Amazon SES (
_amazonses._example.example.org TXT xxxyyyzzz) are already set.
