SmarterMail can support encrypted login using TLS (Transport Layer Security) or SSL (Secured Socket Layer). To take advantage of this feature, you will need to configure your email client with the correct TLS/SSL settings.
TLS vs SSL
There are two email settings you can choose to encrypt your remote connections between your email client and our mail server: TLS or SSL. We recommend using TLS (or "Auto," if available). If you need to manually set the ports, please use these settings:
SMTP TLS (Port 25 or 587)
POP TLS (Port 110)
IMAP TLS (Port 143)
Some older email clients may not support TLS. If you use SSL as the encryption method you will need to specify these ports in your email client:
POP3S - SSL (Port 995)
IMAPS - SSL (Port 993)
SMTPS - SSL (Port 465)
Common name mismatch warning:The certificate installed on the Winhost email servers has a common name of *.internetmailserver.net. If you are using your own domain name as the email server (e.g. mail.yourdomain.com) a warning message may appear. The warning can be bypassed and the certificate trusted.
If you replace the server name in your email client with the specific server name (changing
mail.yourdomain.com to mXX.internetmailserver.net), you can avoid the certificate mismatch warning. Contact support to obtain the name of the mail server hosting your domain or log into your Winhost control panel and under the Domains Manager page view the destination mail server of your MX record.
