E-mail address syntax check

During this step, YL Mail Verifier marks invalid such addresses as username#gmail.com, john!@$gmail,com, etc.

The availability of e-mail domains

During the second step, the program checks the availability of domains, i.e. it marks valid such addresses as user#yahoo.com, user#hotmail.com and marks invalid any nonexistent domain (for example, user#hhfdjggyt1.com, user#jhhfuyq1lj.biz)

The existence of e-mail addresses on their mail servers

During the final step, the program tries to establish an SMTP connection with the mail server and checks each email address for validity there.
