Hi Pat,

Using OWA is another option for us, but due to the amount of SPAM we get on
a daily basis, most people prefer to use an IMAP4 client which can integrate
with SPAM filtering software.  Plus, with Exchange 5.5 and OWA, there is not
a "select all" function if you want to delete multiple email messages at one
time.  In other words, you have to individually check each email message for
deletion (very inconvenient).

Am I opening up a can of worms by enabling remote access using IMAP4?  Can I
beef up security on my Exchange 5.5 server?

Thanks in advance.

Why couldn't you use Outlook web access instead of IMAP. The design can be
much more secure with mail access from the internet than would be IMAP. More
functionality also.

Hello all,

Recently, I setup remote access to our Exchange Server for IMAP4 by opening
port 143 on our Cisco box.

Although this is tremendously convenient for our users to access their
office email from home, I'm concerned about the security risks.  
Most of our users are using Outlook Express from home to access their mail
from the Exchange Server.  I noticed that there is an option for "My Server
Requires Authentication" for Outgoing Mail.  Is there anything I need to
setup on Exchange Server 5.5 to increase the security and require that the
users authenticate for Outgoing Mail?

Any other words of wisdom, in terms of securing Exchange Server 5.5 for
remote email access?

Thanks in advance.
