Re: Outside recipients cannot reply



Where are the MX records pointing currently? To the ISP? Can they still
accept mail?

We usually don't flip MX records until a week-end, and we 'pre-stage' the
event by lowering the SOA refresh intervals. But in your case, I would be
tempted to bite the bullet and just do it. Of course there may be
mitigating reasons why you don't want to do that...
