Fail Safe
The Fail Safe Disaster Recovery Service provides protection against lost emails in the case
when your inbound email server (a.k.a. Customer MTA server) may be unavailable to
receive email. If you have multiple inbound servers configured in Email Protection, all of
these servers must be unavailable before Fail Safe is invoked.
When your inbound servers becomes unavailable, Fail Safe begins
spooling
email, which
means Fail Safe stores your emails in a temporary location until your inbound server
becomes available. Once any of your inbound servers become available, Fail Safe begins
unspooling
the emails. That is, Fail Safe restores these stored emails to the inbound server
using the
first in, first out
order.
The messages Fail Safe stores are not available until the messages have been unspooled.
Fail Safe has an unlimited amount of storage capacity but removes messages that have
been in Fail Safe storage for more than 5 days.

Email Continuity
Email Continuity saves messages for later delivery if your mail server becomes
unavailable. When your mail server becomes available, Email Continuity delivers the
messages. Users can access their messages through a Web-based interface while messages
are in Email Continuity only.
Email Continuity also has unlimited storage capacity and removes messages that have
been in Email Continuity storage for more than 60 days.
