I have a rented server which I use to host my clients websites on. We have facing 2 issues that we would like you to fix.
ISSUE #1: When accessing cpanels for any of the domains we get this notificaiton:
This Connection is Untrusted
You have asked Firefox to connect securely to [url removed, login to view], but we can't confirm that your connection is secure.
[url removed, login to view] uses an invalid security certificate.
The certificate is not trusted because it is self-signed.
The certificate is only valid for [url removed, login to view]
(Error code: sec_error_untrusted_issuer)
ISSUE #2: When sending out emails some clients face this issue with some of the emails they send:
SMTP error from remote mail server after RCPT TO:<>:
450 <>: Recipient address rejected:
Valid DNS required on connecting IP (our server ip) [121KOK0EU700]:
retry timeout exceeded
And sometimes they get mail delivery error: # 554 This server requires PTR for unauthenticated connections.
We would like you to identify why we are having these issues and fix it for us permanently. Thank you

I put two days counting the delay of DNS propagation. Probably the issue could be fixed in 2 hours, but i should take a look before i could grant a date.
