Hard to say. Might be a serve glitch.

Thank you Erel for your response.
My application was OK for 5 years until 01/08/2025

The code is :
Sub SendMessage (SMTP As SMTP, Ademail As String, Corpsmail As String)
SMTP.Initialize("smtp.free.fr", 465, "***************@free.fr", "**********", "SMTP")
SMTP.UseSSL = True
SMTP.To.Add(Ademail)
SMTP.CC.Add("****************@gmail.com")
SMTP.Subject = "Facture"
SMTP.Body = Corpsmail
SMTP.AddAttachment(File.DirRootExternal , "Facture.pdf")
ToastMessageShow("Envoi de la facture en cours", True)
SMTP.Send
End Sub

Sub SMTP_MessageSent(Success As Boolean)
If Success=True Then
ToastMessageShow("Email transmis", True)
Timer1.Enabled = True
Else
ToastMessageShow("Email non transmis", True)
Log(LastException.Message)
End If
End Sub

Now : java.lang.RuntimeException: Error sending message: 550 5.0.0 message does not have exactly one Date field

I have the last version of Net Library
If you have an idea perhaps to change the smtp server for a test ?
Thank you

Whenever you see code with File.DirDefaultExternal or File.DirRootExternal you immediately know that it is broken code.

That was written by Erel in 2022.

My application was OK for 5 years until 01/08/2025

That is probably the root of your problem - it is time to update it. Start by using XUI.DefautlFolder but be prepared for other changes.

Thanks Erel
I will update my application.
Sorry but I think there must be another explanation for this problem because when I don't attach any files I still have the same error ...

Thank you

. . . there must be another explanation for this problem . . .

Yes, that is probably true. Your post suggests that you have not changed your app for five years, but in that time Google has introduced two-step verification, for example. You don't make it clear in your post if that affects your usage case.

I think that the modification is on the Free SMTP server.
I choose another professional SMTP server (BREVO) with the port 587 and I modify the code with :
SMTP.StartTLSMode = True
instead of :
SMTP.UseSSL = True
and now it's OK
Thank you for your help.
