Hello again, I'm using the _INetSmtpMail from <Inet.au3> but unfortunately it doesn't send <html> content. Ofc I looked up the code in Inet.au3 and found the content-Type entry but I don't know what I have to modify to make it work. Anyone an idea ? $aSend[4] = "From:" & $sFromName & "<" & $sFromAddress & ">" & @CRLF & _ "To:" & "<" & $sToAddress & ">" & @CRLF & _ "Subject:" & $sSubject &am
