thunderbird failed to find settings for your email account

Hello

we have just setup sentora on our dedi-server using CentOS 7.2 64-bit as its OS, we then created a mailbox on the server, it works fine through its online client, But when we try to access the email using mozilla thinderbird, we get the following error:

thunderbird failed to find settings for your email account

we tried both "IMAP/POP3" and the posts are set o be auto, so are "SSL" and "authentication".

we are behind cloudflare,so i added new CNAME records for Mail and SMTP pointing towards our domain name. but still it does not work.

this is a screenshot of our thunderbird settings,



can anyone help please?

CNAME must point to an URL not behind cloudflare (grayed).

Don't set settings to auto detect but use manual.

NO SSL and port 25 for SMTP
Port 110 for POP3
Port 145 for IMAP4

thank you! I did what you said, and now thunderbird recognizes the configuration, But says : configuration could not be verified - is the username and password correct?   i am sure the user & pass are correct.
