Unfortunately we have a legitamate user attempting to send inbound email
from his dsl account and cannot get through.

2004-03-15 01:02:57 SMTP protocol violation: synchronization error
(input sent without waiting for greeting): rejected connection from
H=adsl-66-141-211-211.dsl.tulsok.swbell.net [66.141.211.211]

Since most of our users are either doctors or users sending mail to
doctors, we are expected to resolve this issue but I really don't want
to disable protocol enforcement if I do not have to.

We have tried to contact swbell.net via email and by phone but keep
getting the run-around or just plain ignored. Anyone else having
trouble with swbell.net?

Thanks
