After migration from Contabo to OVHCloud VPS receiving email fails

[stepcellwolf]

I do not have this as an option.

I have those two DNS servers added:

[jarod5001]

And you can’t remove them! Hope ovh support understands what needs to be done, since you don’t need their dns servers.

[stepcellwolf]

No I can not remove them, indeed.

I just noticed in rspamd interface I still have the old hostname with sso.domain.tld
Can this be an issue?

After 48 hours, I transferred the domain name, and everything seems to be working now.

However, a few steps have been taken:

1. IPv4 only
2. No second DNS/ DNS reverse
3. Delete cloudinit DNS IPs from /etc/resolvconf/resolv.conf.d/head and
4. Domain name register transfer.

I hope that this will be a long-term solution and that I will not need to come back and ask for help here. Thanks to all for their great support.
