if for some unlikely reason...your e-mail account were to be unavailable for a period of time, what happens to any mail that might have been sent to you in that time... does it just bounce back to the sender as UNSENT ? or does it get directed somewhre else...only to appear in your inbox when the service resumes? and also would the same be for FORMS? that are forwarded to e-mail addresses? they would just be lost????
Email that is not available generally will bounce as unsent, sometimes with a delay message, *unless* your host has a system set up that collects or redirects it, in which the email is delayed but gets to you. Sometimes they queue it up and send when the mailserver is working again. If the email is donw because the domain name expired; it will bounce; won't be resent. Same goes for forms.
It depends. How many MX records do you have? If it might be one, and that email server is down - then there is a chance it can be bounced. But some email servers also are set up to retry every 5 minutes, every 10 minutes, etc for a few times, maybe 4 or 5 times, just in case it was rebooting or something. As far as the forms, if they were sent from your email address, they might be bounced back to you. If they were sent from the person's email address, they might be bounced to them
