[RESOLVED] System.Web.Mail.MailMessage fails 1 in every 5 mails

[PVR]

From my application which is running on a win2003 server, I send mail using .System.Web.Mail.MailMessage:

Public Sub SendMail(ByVal FromText As String, _
ByVal sendToText As String, ByVal SubjectText As String, _
ByVal BodyText As String)
If sendToText.ToString.Trim.Length >= 0 And FromText.ToString.Trim.Length > 0 Then
myMessage = New MailMessage
System.Web.Mail.SmtpMail.SmtpServer = "xxx.com"
Try
With myMessage
.BodyFormat = MailFormat.Text
.Priority = MailPriority.Normal
.To = sendToText.ToString
.From = FromText.ToString
.Subject = SubjectText.ToString
.Body = BodyText.ToString
End With
System.Web.Mail.SmtpMail.Send(myMessage)
Catch ex As Exception
MsgBox(ex.Message, MsgBoxStyle.Information)

End Try


Now what happens is, that there is an irregular CDO error message. The first time I run it, 4 messages are being sent and on number 5 I get a "Could not access CDO.message object" error. Then I send another 5 messages in a row, and number 3 would fail, or number 1. So no pattern at all.

Anyone seen that behaviour before?
