Effects of DMARC record
-
I followed your tutorials in setting up WP Mail SMTP with SendInBlue. As of this writing, SendInBlue has successfully authenticated the domain.
When I send a test email from WP Mail SMTP, it still presents the message that DMARC has not been set up (and a search for “dmarc” in the header code turns up nothing). MX Toolbox also shows no DMARC record.
I set it up about 4.5 hours ago, and my hosting service’s TTL is 1 hour (not changeable by the user).
I suspect I simply need to wait longer for it to propagate.
Meanwhile, I have two beginner’s questions:
Will the DMARC record have any effect on messages that are sent outside of SendInBlue?
For example, suppose a customer makes a purchase from my site and receives a confirmation email sent by the WP Mail SMTP plugin via SendInBlue from [email protected].
The customer replies to that message, and I retrieve it NOT via the SendInBlue site but through the email client on my computer.
When I reply to it, will the DMARC record on the server cause any problems since this message won’t be going through SendInBlue (for example, causing the recipient’s server to think it’s spoofed)?
Also, will the DMARC record have any effects on other email accounts on the same server that are not associated with my web site or SendInBlue?
I could simply wait till the DMARC record propagates and see what happens, but if this is going to cause problems I’d rather remove it right away.
Thanks!
