Error Type: SMTPHeloError Error Value: (501, 'Invalid domain name')
Does anybody know what causes this. The server name I've used is correct,and I am able to ping it from my NT server.
An SMTPHeloError is what you get when the server doesn't accept your try to connect. The 501 error is what the server tells you, so it seems it thinks that the domain name of the connecting machine is incorrect.
