Mail Server Configuration (IMAP, POP3, SMTP)

Use these configuration settings to set up your business email address in external mail clients such as Microsoft Outlook, Apple Mail, Mozilla Thunderbird, iPhone/iPad, and Android devices.

Recommended Configuration (Secure SSL / TLS)

Key Notes for Setup

• Server Hostname: Always use mail.coliserver.com for incoming and outgoing servers.

• Authentication: Ensure "My outgoing server (SMTP) requires authentication" is checked in your mail client settings.

• IMAP vs. POP3: We recommend IMAP so your emails, folders, and read statuses synchronize across all your computers and mobile devices.

• Webmail Access: You can also access your email anytime through a browser at https://cp.coliserver.com:8090/snappymail.
