If your mail server goes down, we'll automatically keep trying to
deliver your messages for 5 days. In fact, we also archive all messages
for free for 30 days, and you can either redeliver emails individually,
or have us re-queue them for you in bulk. Archival times longer than
30 days are not yet available, but we're considering it.
You're in good company! Postini customers are moving over to SpamHero in droves right now. It's easy to switch to SpamHero from Postini. Note that when you place your order, that our ordering system will detect the Postini mail servers as your mail delivery host rather than your real mail server, so be sure to change the Mail Delivery Host setting in SpamHero to match the real hostname of your mail server(s).
