Hi, I've enabled "Require that all senders are authenticated" in Distribution Group ID in Exchange 2007. While sending mail through any script with SMTP authentications credentials I'm not receiving mails instead of that getting error like "550 5.7.1 RESOLVER.RST.AuthRequired; authentication required" Please anyone help me on this.

Senthil KR How have you verified that your script is successfully authenticating?---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

Yes, Rich is right.Before checking the script, send a test mail from your email account or any authenticated user account to same DL. If mail succesfully drop then check your script.ThanksAmit

Hi, Thanks for the reply. By using outlook with a authenticated user able to send/receive mails. I'm using the below script to trigger automated emails, which is not working fine. Set objMail = Server.CreateObject("Persits.MailSender") objMail.Host="SMTP SERVER" objMail.From = "From Email Address" objMail.Username = "user name" objMail.Password = "password" objMail.FromName = "From Name" objMail.Subject = "Subject" objMail.Body = strBody objMail.addaddress "Recipient Email address" The above script able to trigger mails to recipient however its blocking from the exchange and gives sends me "550 5.7.1 RESOLVER.RST.AuthRequired; authentication required" error message. Thanks, Senthil KR

Thanks, Senthil KR You'll have to take this up with the provider of the software you'reusing to send the e-mail.http://www.aspemail.com/manual_object.html#SendEncryptedLooks like section 5 of the user manual is where you want to look.---Rich MatheisenMCSE+I, Exchange MVP--- Rich Matheisen MCSE+I, Exchange MVP

Senthil,Accroding to error message, it is happening because the user, you are using in your script is either not authenticated or credentials are wrong?So work on this area?Like you said Authenticated users are able to send/receive the mails, so use the same username in your script and then try again?Let me the output.ThanksAmit Rawat
