There’s been a change in Most Wanted Web Services policy and server configuration in regard to secure e-mail. Our servers will no longer allow plaintext authentication for sending and receiving mail. We will be making the following configuration changes to make e-mail more secure on our servers.
- Receiving e-mail
- The allowing of plaintext authentication for POP3 and IMAP will be disabled.
- Connections to the server on ports 110 and 143 will not be allowed.
- Sending e-mail
- E-mail clients will be required to connect with SSL or issue the STARTTLS command before being allowed to authenticate.
- With that said, we recommend the following settings for your e-mail clients (Outlook, Thunderbird, etc.)
Secure SSL/TLS Settings (Recommended)
Username: Your full email address.
Password: Use the email account’s password.
Incoming Server: YOUR SERVER HOSTNAME
IMAP Port: 993
POP3 Port: 995
Outgoing Server: YOUR SERVER HOSTNAME
SMTP Port: 465
Authentication is required for IMAP, POP3, and SMTP.
For your convenience, we explain below how to set up a new account with the correct settings and modify an existing account for both Thunderbird and Outlook.
