'verify certificate' warning
I have been having this annoying little problem ever since switching webhosting servers with Verio. Everytime I boot up Mac mail, I get a popup warning titled 'Verify Certificate' and the body of it says 'Mail can't verify the identity of "my IP address here". The certificate for this server is invalid....(see attached jpg for visual), it also gives three button choices 'Show Certificate', 'Cancel' and 'Connect'. I always hit connect and everything is fine. I tried finding out about this certificate stuff through the 'help' section of the finder. It pointed me to the 'Keychain Access' utility. I opened that up and clicked on the category 'Certificates' in the left hand column (again see attached jpeg).
The certificate listed is from verio.com so I assume that this is the 'invalid certificate'. I also see that the number 19 is included in the certificate name, which is the group number of my previous server. So my questions are:
1. What is the fix here?
2. Can I just delete the existing certificate?
3. Do I need a certificate in order to log in to mac mail and access my mailserver?
4. If so, where do I get a valid certificate for my new server, verio?
Thanks in advance for any input.
Best,
Dennis
