I think the ones I’m referring to are subdomains for Network Solutions Email. I also read somewhere that Cloudflare “flattens” CNAME records if you have the setting enabled to automatically do it, but we don’t have that function available as we’d have to upgrade to do that. The following are examples of the records I’m talking about:
imap . musicrhapsody.com . netsolmail . net
pop. musicrhapsody.com . netsolmail . net
Also the reason I’m concerned about this is that all my Network Solutions mail keeps going to the spam folder even though all my DNS records appear to be set up correctly.
Do emails go to spam with all recipients or only some?
Network Solutions is listed in the UCEPROTECT level 2 and level 3 blocklists. A known user of this blocklist is Microsoft’s free email service, so all emails to them would definitely go to spam.
I’m not sure how much trouble the reverse DNS mismatch would cause.
DNS is quite involved in your reputation when sending email.
But for receiving email, it only publishes the IP that emails are supposed to be sent to (with some exceptions that are irrelevant here). Either the emails arrive in your mailbox or they don’t.
At that point, your email provider decides what to do with the mails that arrive, like sorting them into different mailboxes, marking them as spam etc.
Did you test this with email from different services? Like gmail, hotmail etc?
Yes emails from all different services are going to our spam folder. Some I don’t even think we are receiving because Network Solutions sent us a test email and we never received it. I also just sent an email from my personal email to that address and never received it there either.
