Verification Rules are methods to override normal verification for e-mail addresses that match a pattern. For instance, you may want to mark all e-mail addresses belonging to yahoo.com as Valid or Do Not Check because yahoo.com always returns a valid result. Rules help to reduce the time it takes to verify e-mail addresses.
To change the Verification Rules, click on the Tools menu and Options, then select the Rules tab.
To add a rule, click Add. The Add Rule dialog will be displayed. Enter an e-mail address or domain name, select a Rule and click OK. All e-mail addresses matching the entered string will be processed as per the rule. You may also use wildcards as an e-mail address or domain name.
For instance, if you wish not to verify all e-mail addresses belonging to yahoo.com, click Add. Enter "*@yahoo.com" as E-mail or Domain Filter. Select Do not verify from Rule and click OK. During verification if an e-mail is found belonging to yahoo.com (matching the string "*@yahoo.com"), it will not be verified and the text "Did Not Verify: By Rule" will appear in the Result column.
To edit a rule, select the rule to be edited and click “Edit”. You may change the e-mail/domain name and/or the rule. Click OK after editing the rule.
To remove a rule, select the rule and click "Remove". The rule will be deleted.
