One of my resold accounts uses an MX entry to send email directly to his Exchange server. His server is going offline for a week, but obviously they don’t want to lose any mail.
My question is .. how long will Jodo’s servers keep trying to deliver mail for before bouncing it? Or would I be better reverting to the default MX records and collecting mail in a standard POP account?
Well it won’t retry for a week, what I would do in this case is actually turn the hsphere mail service on and make a few of the most common mail boxes with a generic password that maybe you and their exchange admin know. Then they won’t miss mail, and they can pick it up from a different server. You could make this a higher MX record than the exchange server and even leave it like this after it is running.
