Wanted to see if any attachments are being sent out


Hey Folks,

I am deploying squid proxy+email server on Linux and may be commercial content filtering like websense or trendmicro which will have network DLP solution. What I wanted to know if there is any way available on Linux or any other Open source software available to verify and alert or log if any attachments are being sent out

Thanks
Manya

Snort Community rules and Emerging Threats rules have signatures for signaling email attachments using "content:"Content-Disposition". Grep rules, reverse flow (prolly), test rules. Wrt DLP you know data can leave the premises in more than one way*. If not entertaining at least it should be a cue to think about it as software does not solve all problems.
