*  The mailman object is used for sending and receiving email.
loMailman = CreateObject('Chilkat.MailMan2')

*  Any string argument automatically begins the 30-day trial.

lnSuccess = loMailman.UnlockComponent("30-day trial")
IF (lnSuccess <> 1) THEN
    =MESSAGEBOX("Component unlock failed")
    QUIT
ENDIF

*  Set the SMTP server.
*  This code was tested against both mail.chilkatsoft.com
*  and smtp.comcast.net

*  mailman.SmtpHost = "mail.chilkatsoft.com";
*  mailman.SmtpUsername = "admin@chilkatsoft.com";
*  mailman.SmtpPassword = "****";

loMailman.SmtpHost = "smtp.comcast.net"

*  Create an email object.
*  We'll never actually send this email.  It's only used
*  to test the recipients.
loEmail = CreateObject('Chilkat.Email2')

loEmail.Subject = "This is a test"
loEmail.Body = "This is a test"
loEmail.From = "Chilkat Support <support@chilkatsoft.com>"

*  Add recipients to be checked.
*  (When this was tested, a_real_person was replaced with
*  a valid email address.)
loEmail.AddTo("A Real Person","a_real_person@comcast.net")
loEmail.AddTo("Testing","doesNotExist7434@comcast.net")
loEmail.AddTo("Admin","admin@chilkatsoft.com")
loEmail.AddTo("Not Exist","doesNotExist@chilkatsoft.com")
loEmail.AddCC("Not Exist","DoesNotExist7213@gmail.com")
loEmail.AddBcc("Exists","chilkat.support@gmail.com")

*  NOTE: A mail server can only verify the email addresses
*  specific to it's domain.  Therefore, when using smtp.comcast.net,
*  only comcast.net email addresses will be flagged as invalid,
*  and when using mail.chilkatsoft.com, only chilkatsoft.com
*  email addresses are flagged as invalid.

*  Return all bad email addresses in saBadAddrs:

loSaBadAddrs = loMailman.VerifyRecipients(loEmail)
IF (loSaBadAddrs = NULL ) THEN
    =MESSAGEBOX(loMailman.LastErrorText)

ELSE
    *  List the invalid email addresses:
    IF (loSaBadAddrs.Count > 0) THEN

        n = loSaBadAddrs.Count
        FOR i = 0 TO n - 1
            ? loSaBadAddrs.GetString(i)
        NEXT

        *  Examine the SMTP session log to see how the email
        *  addresses were caught:
        =MESSAGEBOX(loMailman.SmtpSessionLog)

        RELEASE loSaBadAddrs
    ENDIF
