I have three forms on my site that all use the same jmail code and were working up until now even though we have not made any changes to our site.  The code is as follows:

 Set JMail = Server.CreateObject("JMail.SMTPMail")

  JMail.Logging = true
  JMail.ContentType = "text/html"

' This is my local SMTP server

  JMail.ServerAddress ="mail.rms-hrmgr.com"

  Jmail.Sender = "administrator@rms-hrmgr.com"

  JMail.AddRecipient "support@rms-hrmgr.com"

  JMail.Subject = "Product Update"

  JMail.Body = strData

  JMail.Priority = 2

  JMail.AddHeader "Originating-IP", Request.ServerVariables("REMOTE_ADDR")

  JMail.execute

  JMail.ClearRecipients()

  set JMail = nothing

' END JMail Application1

and here is the error:

jmail.SMTPMail error '8000ffff'

The message was undeliverable. All servers failed to receive the message

/contactus_feedback.asp, line 37

Any help is greatly appreciated,

Gary
