He agrees /_with me putting Exchange and Outlook Web Access /_out there is not a good idea, from a security /_standpoint. So we're looking for a good OSS /_solution. I know I can use products like /_squirrelmail and Horde's IMP to provide a /_web-based email front end, but how can I provide /_POP/IMAP clients access to their Exchange /_mailboxes, without opening up ports to the /_Exchange box? Is there OSS software that will do /_this? I had a similar situation and here is how I had it configured: 1. Debian/Apache (SSL) running IMP on the Intranet side (complete w/LDAP to addressbook) 2. OpenBSD Firewall that redirected port 443 to server in #1 3. #1 was on same LAN as Exchange, so they played happily together. Never had a problem. Of course, when I left, they plopped Exchange out onto the Internet and fired up OWA. Their problem at that point :-) v/r -Mike
