SMTP Proxy: Filter email by address pattern

The options on the SMTP Addressing tab allow you to put limits on who can send email to your email server,
and who can receive the email.
Block email from unsafe senders
Select this check box if you want to put limits on email to allow email into your network only from
specified senders. The default configuration allows email from all senders.
Limit email recipients
Select this check box if you want to allow email to only some of the users on your network. This can
be useful if you want to prevent people from using your email server for email relaying. To do this,
make sure that all domains for which your email server accepts email messages appear in the rule list.
Make sure you use the wildcard format such as *@mywatchguard.com. Any email with an address
that does not match the listed domains is denied.
