Hello,

I have a custom SMTP Server and therefore I want to make a cleanup of DNS entries. I don't need OVH email web client as well. I've already removed MX records but I'm not sure about remaining ones:
autoconfig.. 0 CNAME mailconfig.ovh.net.
autodiscover.. 0 CNAME mailconfig.ovh.net.
_imaps._tcp.. 0 SRV 0 0 993 ssl0.ovh.net.
_submission._tcp.*. 0 SRV 0 0 465 ssl0.ovh.net.

I haven't found any details about necessity of this entries in the guides of my email service provider and they seems to be OVH-specific. Can anyone confirm it is safe to remove them?
