Can the users access Europa email server from external internet?
It depends on what is the access means: • Web email client and Quarantine Manager access: add the HTTPs (default is 443) port forwarding rule into your firewall. • POP3 access: add the POP3s (995) port forwarding rule into your firewall. • IMAP access: add the IMAPs (993) port forwarding rule into your firewall. • SMTP send access: add the SMTPs (465) port forwarding rule into your firewall. Add a DNS entry (see the “DNS requirement for internal/external web access” FAQ above).
