Barracuda versus Symantec Mail Security for Exhange
Posted on 2006-11-25
Our Barracuda Firewall gets over 90,000 emails a day and blocks over 80,000. A lot of the blocked spam has .jpgs attached. Barracuda does not have a way to whitelist a sender with a .jpg attached so even ligitimate mail with a .jpg is being blocked. This is a real pain and takes a lot of admin time during the day to unblock these legitimate emails.
I am thinking about letting all .jpgs through the Barracuda firewall and letting Symantec Mail Security catch them. I can setup an allow list of legitimate senders in Symantec.
My concerns are:
1. Will this be a security risk to allow all .jpgs through the Barracuda firewall and let Symantec filter them?
2. Will this degrade performance on my Exchange boxes since they will be doing the processing instead of the Barracuda
3. Will this take up more storage on my Exchange boxes and how fast?
I will greatly appreciate your answers to the above questions.
