Hi,
Thank you for posting here.
According to your description, I understand you receive spam mail on mobile
device. If I have misunderstood your concern, please feel free to let me
know.
Please understand place spam mails to Junk email folder of client is a
client anti-spam function, only apply for MPAI client( Outlook 2003)
connect to exchange server. So based your situation, I would suggest that
you enable spam filter on server side.
Currently, Exchange Server 2003 SP2 supports the following filters:
1. IP restrictions on a virtual server basis
2. Connection filtering
3. Recipient filtering
4. Sender filtering
5. Sender ID filtering
6. Intelligent message filtering
More Info:
Exchange 2003 Server Service Pack 2 (SP2) Anti-Spam Framework
http://blogs.technet.com/exchange/archive/2005/07/18/407838.aspx
Generally, Connection filtering is used to configure Exchange Server 2003
to contact a Realtime Block List (RBL) provider to determine whether the
computer that an e-mail message is sent from appears in a list of
"blacklisted" computers. You can also configure exceptions to these
connection filters. You can use several connection filters to prioritize
the order that each filter is applied in. If multiple RBL providers are
used, each provider is queried in the order that they appear in Exchange
2003 and Exchange does not query other RBL providers in the list if it
obtains a match from a previous provider.
To configure Connection filtering, we have two main steps:
1. Create a connection filter
2. Apply the connection filter to the appropriate SMTP virtual servers
The detailed steps are provided in the following Microsoft KB article. To
shorten my post, I did not list all of them as below. Thank you for your
understanding.

(RBLs)
http://support.microsoft.com/?id=823866
For general information about these anti-spam features in Exchange 2003,
please refer to the following Knowledge Base (KB) article:
821746.KB.EN-US HOW TO: Prevent Unsolicited Commercial E-Mail in Exchange
2003
http://support.microsoft.com/default.aspx?scid=KB;EN-US;821746
Also, as you may already know, these anti-spam features still need
administrators to manually configure and set up according to specific
requirements. However, we will release a new product called Intelligent
Message Filter, which can be used to integrated with Exchange 2003 Server
to provide smart anti-spam functions. For more info about this new product,
please refer to the following Web page:
http://www.microsoft.com/exchange/techinfo/security/imfoverview.asp
New white paper for IMF v2 is available, please refer to following website.

Hope this helps, if you have any other concerns or need more help, please
feel free to let me know.
Have a nice day!
Best Regards,
Chace Zhang (MSFT)

| Some spam mail is gitting through Exchange to the mobile devices even
though
| Exchange is placing it in the spam folder on the desktop. Running latest
| service packs on SBS2003 and Exchange.
|
| Does Exchange filter the emails first then forward them to the mobile
| device? I seem to get the emails on my Treo 700 within seconds of
receiving
| them on my desktop, so I am thinking Exchange should be sending the email
| through it's spam filters.
|
| Any ideas? Thanks
