Coming back to the original problem, that Gmail was flagging
Jaroslaw's non-list messages as spam. Would removing Jaroslaw's
email address from Postfix list mail have changed the 'spam'
disposition of his non-list messages? The response from Gmail staff
implies that his list messages were a factor in the spam ruling (as
reported by Jaroslaw).
