My apologies, I see what you mean (have never looked at the header of a sent item before!). From your e-mails, I see that you are sending to a local account. Try sending to an external "real" account (send it to me if you like - I don't think that a hotmail account will give us the info we need), then we can see if it is an internal or external issue.

If this is the case - there is no detail in here(i.e. it is blank). If you can offer any thoughts on this they are appreciated - as the supposed experts from ACCPAC cannot decide what is happening - hence me trying to find out using this forum as a resource.
