ASPMail Server Authentication

[csiwa28]

Recently our ISP increased their security and they now require SMTP authentication. We're using ASPMail (SMTPsvg.Mailer) and now all our forms won't send out mail. Using ASPMail, is there a way to send a user name and password in order to authenticate? If not, we found a 3rd party software that does called MailBee - anyone hear/use it?

Any insight is appreciated.
