IsabiMail Suite IMAP, SMTP, and POP3 Server Settings

IsabiMail Suite Email Server Settings

Use these settings to connect any email client to your IsabiMail Suite account. The server hostname for all protocols is mailserver.isabi.email.

IMAP Settings (Recommended)

IMAP keeps your emails synced across all devices. Changes made on one device (read, delete, move) reflect everywhere.

Setting	Value
Server / Hostname	mailserver.isabi.email
Port	993
Security	SSL/TLS
Username	Your full email address (e.g. john@yourdomain.com)
Password	Your IsabiMail Suite account password

SMTP Settings (Outgoing Mail)

Use these settings to send email from any client.

Setting	Value
Server / Hostname	mailserver.isabi.email
Port	587
Security	STARTTLS
Username	Your full email address (e.g. john@yourdomain.com)
Password	Your IsabiMail Suite account password
Authentication	Required

POP3 Settings

POP3 downloads emails to your device and removes them from the server. Use IMAP instead if you access email from multiple devices.

Setting	Value
Server / Hostname	mailserver.isabi.email
Port	995
Security	SSL/TLS
Username	Your full email address (e.g. john@yourdomain.com)
Password	Your IsabiMail Suite account password

Verify Your Connection

If you have trouble connecting, use these tools to check your setup:

• SMTP Test — verify your outgoing mail server is reachable
• MX Lookup — confirm your domain MX records point to mailserver.isabi.email
• Blacklist Check — make sure your sending IP is not blacklisted
