Port Requirements

Port Protocol Purpose
143 IMAP Standard IMAP mail access
993 IMAPS IMAP over SSL (recommended)
7071 Admin Zimbra admin port for system info
443 HTTPS Web service access via SSL

SSL Recommended

For secure migrations, use port 993 (IMAPS) instead of port 143 for encrypted mail transfer.

Firewall Configuration

If your organization requires firewall rules for external connections, you'll need to allowlist Cloudiway's IP addresses to enable the migration.

Getting IP Addresses

Contact Cloudiway support to obtain the current IP addresses that need to be allowlisted in your firewall for migration connectivity.

Required Outbound Access

  • Zimbra server ports (143/993, 7071, 443)
