Secure SMTP / POP use different ports than their plain-text counterparts. Take a look in the Protocols list and you'll see what I mean. You can use the same IP for those. What you cannot do is define multiple publishing rules for the same IP/protocol/port combination.

Must I use additionally IP addresses for secure POP3/IMAP4 virtual servers? Or can I use the same IP address for both non-secure and secure POP3/IMAP4 virtual servers? I read in ISA 2004 / Exchange 2003 documents that I must use two different IP addresses for both connections.
