Mailbux IMAP, SMTP, and POP3 Server Settings
Mailbux Email Server Settings
Use these settings to connect any email client to your Mailbux account. The server hostname for all protocols is my.mailbux.com.
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 | my.mailbux.com |
| Port | 993 |
| Security | SSL/TLS |
| Username | Your full email address (e.g. john@yourdomain.com) |
| Password | Your Mailbux account password |
SMTP Settings (Outgoing Mail)
Use these settings to send email from any client.
| Setting | Value |
|---|---|
| Server / Hostname | my.mailbux.com |
| Port | 587 |
| Security | STARTTLS |
| Username | Your full email address (e.g. john@yourdomain.com) |
| Password | Your Mailbux 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 | my.mailbux.com |
| Port | 995 |
| Security | SSL/TLS |
| Username | Your full email address (e.g. john@yourdomain.com) |
| Password | Your Mailbux account password |
