Send mail with SendGrid and ASP 3

How do I send email with SendGrid using ASP 3?

I use the Persits.MailSender component of asp 3 to send emails. Localhost works normally, but when I put the sendgrid smtp it will not, it gives error:

  

Persits.MailSender.4 error '800a0017' The password is too long.

By sendblaster the same account, with user and password send broker using SendGrid.

Mailer.Host = "smtp.sendgrid.net"
Mailer.Username = "usuario"
Mailer.Password = "senha"
