Is is possible that your smarthost authenticates you by virtue of IP
address if you use the "old" DSL provider so that your SMTP AUTH has
never actually work.

I suggest using swaks to send test e-mails with and without
authentication via both DSL providers to the same smarthost and find
out when the smarthost accepts your messages and when not.
