We seem to have stareted to get increased number of spam emails in the last few days.
Current infrastructure is
A PIX firewall, Exchange 2003 SP2 and Kaspersky Security 5.5 for Exchange Server 2003.
We have anti-spam and anti-virus enabled on the Kaspersky.
All clients have Kaspersky Anti-virus with anti-spam feature enabled in outlook.
We have IMS set to SCL rating of 7 - although we know we can change this to improve black list etc. we use emails for alerting and this can stop vital messaging emails.
We are looking to what we can implement in the current environment to help. Be it on Exchange, additional tools, to reduce/minimise these SPAM mails.
Would appreciate any ideas and thoughts on what we could implement or what we need to change .
Thanks look forward to any suggestions.
