What is the correct syntax for using wild cards (*) when entering Blocked and Approved Senders?
Valid e-mail addresses are of the form user@host.domain. The “user” may contain alphanumeric characters, the underscore (_) and the dot (.). The “host” may contain alphanumeric characters and the underscore. The “domain” may contain alphanumeric characters, the underscore and the dot. Wildcards may also be used. Wildcards are used to match all users at a particular domain. The wildcard character is the asterisk (*), which will match any set of alphanumeric characters and underscores. To match bob@nowhere.com one would use *@nowhere.com. To match bob.smith@nowhere.com one would use *.*@nowhere.com. To match anyone at nowhere.com, one would use **@nowhere.com.
