Re: Incoming Mail When Exchange Server Down by Dvord

The internet is pretty fickle. Things happen all the time which are
completely out of the hands of mail admins which break the connection to
mail servers the world over.
Because of this, most default configurations for mail allow for retries. So
if the sending mail server cannot reach the receiving one, they will simply
wait some amount of time and try again. My SMTP server at home was
configured to retry every 4 hours for 2 days. After the first 4 hours, it
sent a message saying mail could be delayed. After 2 days, it will then
bounce.
Users are a little spoiled because for the most part, mail is sent without
obstruction. They assume it's always instantaneous, when in fact it is not,
and there are times it can be delayed.
No worries, if your server goes down for a few hours, you won't lose any
mail.
