Remove VPN users - Mail blocked by IML / SCL
Posted on 2008-10-24
I have set up a remote VPN solution for a client (Cisco ASA running WebVPN) all appears to be fine, however remote users who are emailing other users in the same mail domain. are getting their mail blocked by the Exchange 2003 Intelligent Mail filter.
example header from a filtered email (X-SCL rating of 8) from home worker to office worker:
X-SCL: 8 91.28%
Now I know you can't "whitelist" against the IMF, but you are supposed to be able to bypass it by IP address, so Ive added the IP address of the firewall applieance, and the subnet thats being leased to the remote VPN users. (And enabled this on the Default SMTP virtual Server)
Still the problem remains?
Has anyone Cisco expert or Exchange Expert seen this before? Im loathed to log a call to Cisco TAC because they will blame Exchange and Im loather to call Microsoft for the same reason
