I dont know why you are blaming Gmail for this, Im using a completely different SMTP server and having the same problem. The servers are accepting post most of the time. Its only when we use this copy and paste that things go wrong. Gmail is not closing the connection, true but the likely cause to my mind is that Pmail isnt terminating its part as it should. The copy and paste has knocked something out of kilter.
