Reasons to prohibit use of web mail: waste of company time, waste of company resources, increased exposure to email based attacks, webmail is an avenue for data exfiltration. On Mon, Mar 15, 2010 at 6:07 PM, Gareth Fletcher <gareth.fletcher () gmail com> wrote:
If you have McAfee ePO installed you can creat an access protection rule to prevent certain processes eg Outlook.exe from connecting to explicit remote ports. Only problem is you can't exclude remote IPs (like a legitimate imap server) but if that's ok... Perhaps there is something similar from your AV vendor (if it's different, like symantec endpoint protection?). Firewall rule will work but not if user is offsite.

It seems the most common ports are 110, 465, 587, 993, and 995. Are there others? Any reference are much appreciated. Thank you!
