For details of VSE 8.x supported environments, see KB51111. NOTE: This article applies only to McAfee business and enterprise products. If you need information or support for McAfee consumer or small business products, visit https://service.mcafee.com. 問題Outbound SMTP email is blocked by VSE 8.x Access Protection rule for Port 25.
Blocked items include:
原因The VSE 8.x Access Protection feature allows you to block specific ports. Although standard exclusions are set, you must manually revise these rules according to your environment.
解決策You must manually exclude the process that is being blocked.
IMPORTANT: If the client is managed by ePolicy Orchestrator (ePO), changes that you make via the local VSE Console are overwritten at the next policy enforcement interval. Changes must be made from the ePO console in the VSE policy. For assistance, see the VSE 8.8 Product Guide. NOTE: Ensure you use the exact process name as found in the Access Protection log.
IMPORTANT: If you disable any protection or exclude processes, it carries inherent risks. When you disable the "Prevent mass mailing worms from sending mail" option, it poses substantial risks to the security of your systems. McAfee strongly recommends that you exclude only the minimum number of known and necessary processes.
