The address of your mail server.
The address of your mail server. By default, the component will send outgoing mail via SMTP, and receive incoming mail via POP. Moreover, the component will assume that both servers are located at the address specified by MailServer.
In case you use different addresses for incoming and outgoing mail you should set the POPServer and SMTPServer configuration settings appropriately. You may also set POPPort and SMTPPort in case you use nonstandard ports.
