Strange value in MX record, emails boucing

Hi there,

I’m having some issues with emails bouncing back from my domain. I currently have a Google domain with Netlify hosted, where I have also set up the MX records for my Google workspace account.

I have had some complaints of emails boucing from my domain despite (I believe) doing everything by the books. I then took another look at my MX records and saw some long verification string value in one of the records I did not add.

(I have blanked out the URL as it is a client project, however if this is needed I can provide)

Has anyone had anything similar? And is it possible this could be causing the bounce issue? I know this is a long shot but all other MX tests seem to be in order.

Thanks

hmm, before we dig in, did you see this guide already?
