After some recent updates, various email programs have started requiring SSL connection to mail servers. These issues manifest themselves as "server error" or "can not identify server error" and most commonly occur on Thunderbird and Apple Mail programs; however seeing this error on other email programs is definitely possible.
The most common cause of this error is that the mail server configuration you are using recognizes that the domain you are using for email services has an SSL certificate attached to it. You can verify and check this information by going to your email client's mail server settings where you should see mail.yourdomainexample.com as both the incoming and outgoing server information. You can check if your domain has an SSL certificate by following the steps:
- Log into your TierraNet control panel
- Hover over the 'Security' tab in your control panel, then select 'Security Home' from the drop-down.
If you do not see an SSL certificate in your account, then it is more than likely that the conflicting information caused by the missing certificate and the mail server information are causing the error you are receiving.
To resolve this, you can either purchase an SSL certificate or update the mail server settings on your email client to mail.tierra.net.
If at any point you need assistance with this process please do not hesitate in contacting customer support
