MailTester

MailTester is a website that allows users to check if an e-mail address is valid or not. It also provides information about why a mail might have bounced and technical information about a mail account and its mail server.

To check if an e-mail address is valid, MailTester requires the user to input the e-mail address and then press the "Check" button.

If the e-mail address is valid, MailTester will return a message that says "E-mail address is valid." If the e-mail address is not valid, MailTester will return a message that says "E-mail address is not valid." MailTester also provides information about why a mail might have bounced.

For example, if the mailbox is full, MailTester will return a message that says "Mailbox is full." If the e-mail address is invalid, MailTester will return a message that says "E-mail address is invalid." MailTester also provides technical information about a mail account and its mail server.

For example, MailTester will return the following information about an e-mail account: "E-mail account information: Account type: POP3 Server: mail.example.com Username: [email protected] Password: mypassword." MailTester will also return the following information about a mail server: "Server information: Server type: SMTP Server: mail.example.com."
