Moving on from there I can now refer to the fixed fields by their short name but how to refer to the fields that are not included in this short name list?

PROCEDURE ISMTPOnArrival_OnArrival(toMsg AS VARIANT, tnEventStatus AS VARIANT @) AS VOID
? tnEventStatus
? toMsg.ReceivedTime
? toMsg.From
? toMsg.ReplyTo

All works fine but if I cycle through the field list like so:

FOR EACH oField in toMsg.Fields
	? oField.Name
	? oField.Value
ENDFOR

I find the following field exists:

	Name = "urn:schemas:mailheader:message-id"
	Value = "<MYSERVERaNgEpTX5V30000009f@MyDomain.net>"

Question is how can I refer to this field without having to read and cycle through all other fields in the field list? Does the toMsg.Fields collection have any properties other that Name & Value.

Thanks,
Nick
