针对仿冒邮件，Webmail提供【陌】字标识的特色功能。当外部陌生邮件到达时，系统会自动判别该地址是否为通讯录的邮件联系人，若该地址为外部发件人，在邮件系统WEB端会在该邮件发件人名字上有一个【陌】字标识进行警示。
For phishing emails, Webmail provides a unique feature of '陌' character signal. When an external unfamiliar email arrives, the system will automatically determine whether the address is in the address book. If it is an external sender, there will be a '陌' signal on the webmail for warming.
TIPS:如为常用联系人，可将发件人添加到个人通讯录，刷新后会消除【陌】字标识。
TIPS: If there is a frequently used contact, you can add the sender to your personal address book. After refreshing, the '陌' symbol will be removed.
