Hi again Damba!
I believe were communicating through e-mail also but, hopefully we can help others here as well if they have this issue in the future.
As per your instruction I've tried setting .StrictHost = True
I am still receiving the error:
550 STOR failed: Folder does not exist, or you don't have permission for it
What our buisness partner and I have observed is that during the Passive command before the STOR fires:
227 Entering Passive Mode (10,16,200,10,46,226)
The ip address is the internal and not the external ip address.
Is there away I can change the Passive Mode IP to the external address or possibly there's something else Im missing.
