Secure POP3 Port 995 - 6.Feb.2004 2:22:00 PM

Trying to setup secure POP3 on our front end exchange 2000 server (SP3 and
latest patches applied).

We have a certificate setup on the machine, way back when we got OWA
working, which is working fine.

Connecting to the machine and collecting mail through the front end using
port 110 insecurely works fine but when trying SSL through port 995 the
client won't connect. I have checked the firewall logs and the connection is
allowed to the front end but no activity is being shown requests happening
between the front end the back end server. When you are connecting to the
front end through POP3 insecurely you can see the connections being made to
the back end server.

Looking at the properties on Default POP3 Virtual Server through the
Exchange Manager on the front end. The options on the Access Tab are as
follows. The Certificate and Comminications tabs are greyed out, unlike on
the SMTP and http virtual services (Secure SMTP access works fine aswell).
When selecting the authentication options you can only input you default
domain everything else is greyed out and there is no option for TLS

On the Client I have tried ticking and unticking "log on using secure
password authentication")

Error Message displayed on client (Outlook Express 6).
Your server has unexpectedly terminated the connection. Possible causes for
this include server problems, network problems, or a long period of
inactivity. Account: 'webmail.bridgnorth-dc.gov.uk', Server:
'webmail.bridgnorth-dc.gov.uk', Protocol: POP3, Port: 995,
Secure(SSL): Yes, Error Number: 0x800CCC0F

Any ideas.

What kind of certificate? Is the certificate from a internal cert. service or from a recognised cert. company? May make a different. If internal, then you need to d/l and install the cert before you can use it!

Do not use the secure password authentication box but on the Advanced tab you do need to tick 'This server requires secure connection (SSL)' for POP3.

The certificate is an external certificate from Comodo Class 3 Security Services CA.

I setup the client so it's only using the option discribed, is it normal not being able to view the certificate options on POP and IMAP?
