Re: PIX -> ISA -> OWA Configuration

[Michael Brown <topo2 () pacbell net>]

Or use something like Horde/IMP/Turba on Apache/SSL to get IMAP/SSL
webmail and LDAP/SSL contact info from Exchange ....

That's 2 ports to the backend:
636/tcp or 3269/tcp for LDAP/SSL or GC/SSL (both work, as sadly
Exchange/Win2k/2k3 has no LDAP/TLS

993/tcp for IMAP/SSL (again no TLS)

worked for me...
