Hi Kirti,
You entered "mail.tib.com" somewhere in your mail client (the software that's throwing the error about the certificate mismatch.) However the server thinks its name is "imap.tib.com." Therefore in your client, tell it to connect to imap.tib.com instead of mail.tib.com (e.g. if it's Thunderbird, it'll be in Tools > Account Settings.)
I don't currently use SSL with Dovecot so I do not how the certificate is set up, but with OpenSSL, it's the common name (CN) field in the certificate that defines the server name. I would say it would be much easier to just change the hostname in your client settings.

OK.
Can you tell me where I entered "mail.tib.com" server name when I created a certificate? I do not remember. The only place I can think of is in /etc/postfix:
myhostname = mail.tib.com
However, I did go back & changed it to:
myhostname = imap.tib.com
but the message did not go away!
Do I need to recreate the certificate? If yes, then how is it done?
I think I just installed & setup Postfix, Dovecot, but did not physically created a certificate.
Is the certificate automatically created, from information in /etc/postfix/main.cf, when Dovecot is setup? If that is the case, I can uninstall Dovecot & re-install it unless there is an easy way.
Did I mention that I am pretty new to Postfix & Dovecot (and LINUX in general).
Thanks.
Kirti

Hi Kirt,
Easy! Either connect to imap.tib.com instead of mail.tib.com, or create and install a new security certificate on the server which is for mail.tib.com instead. It's as simple as the message says - you've said your mail server is called "mail.tib.com" but your installed security certificate is for "imap.tib.com."

Setup of Dovecot went smoothly.
Now when I try to retrieve mail from the server, I get the following message:
Security Error: Domain name mismatch
You have attempted to establish a connection to "mail.tib.com" However, the security certificate presented belongs to "imap.tib.com".....
How to fix this message?
Thanks in advance.
