RE: POP 3 Errors/Warnings

Hello John,

Thank you for posting here.

According to your description, I understand that you want to filter the
spam for Public Folders by IMF. If I have misunderstood the problem, please
don't hesitate to let me know.

First of all, I would like to explain the working mechanism of Intelligent
Message Filter in Exchange Server 2003. IMF only works on incoming messages
submitted anonymous. It works at two levels: Gateway level and Store level.
Detailed info as below:

1. If a message is not filtered by connection, recipient, or sender
filtering, Intelligent Message Filter is applied, and one of two things
happens at the gateway:
1). If Intelligent Message Filter assigns the message an SCL rating that is
higher than your gateway threshold, Intelligent Message Filter takes the
appropriate gateway action.
2). If Intelligent Message Filter assigns the message an SCL rating that is
lower than or equal to your gateway threshold, the message is passed to the
Exchange server with the user's mailbox store.
2. If a user is using Outlook 2003 or Outlook Web Access with Exchange
2003, the user's mailbox store compares the message's SCL rating with the
store threshold you configured, and one of two things happens:
1). If the message rating is lower than or equal to the store threshold,
the mailbox store checks the user's blocked senders list configured in
Outlook or Outlook Web Access, and one of two things happens:
- If the sender of the message is not on a blocked senders list configured
in Outlook or Outlook Web Access, or if a blocked senders list is not
available or defined, the message is delivered to the recipient's Inbox.
- If the sender appears on the blocked senders list configured in Outlook
or Outlook Web Access, the message is delivered to the user's Junk E-mail
folder.
2). If the message rating is higher than the store threshold, the mailbox
store checks the user's safe senders list configured in Outlook or Outlook
Web Access, and one of two things happens:
- If the sender appears on the safe senders list, the message is delivered
to the recipients Inbox.
- If the sender does not appear on the safe senders list or if a safe
senders list is not available or defined, the message is delivered to the
recipient's Junk E-mail folder.

As the information above, since you want IMF enable to Public Folders,
there are limitations:
1. Make Public Folders mail enabled.
2. The Spam is come from external via SMTP
3. The IMF can only work at gateway level for Public Folders.

About the value of SCL:

I am afraid it is always hard for us to determine whether SCL is suitable
for your company. By visualizing SCL rating, you can see what kind of
message defined with SCL you determined. And then you can adjust the SCL
settings in IMF Gateway depending on your situation and business concern.

There's a third-party solution which can use a form to show SCL for each
mail as a column in Outlook or OWA:
Exposing SCL (Spam Confidence Level) in Outlook

Exposing the Spam Confidence Level (SCL) in OWA

http://blogs.technet.com/exchange/archive/2004/05/27/143297.aspx
Note: The SCL for the messages in the public folder will disappear when it
is replicated between public folder stores.

Hope this helps. If you have any further concern, please let me know.
Thanks and have a nice day!

Best regards,

Terence Liu(MSFT)

| Hi - the POP connector is part of SBS, not Exchange. Try
| microsoft.public.windows.server.sbs.
| However, note that POP connectors are not recommended, and you would have
| much better mail delivery if you switched to hosting your domain's mail
| directly via SMTP.
|
| Any additional comments would be welcomed.
|
| Thanks.
