35.3.2 Knowing What to Expect in an Internet Agent Failover
Situation
The failover behavior of the MTA for the Internet Agent domain is the same as for an MTA in a
regular domain. See
"Knowing What to Expect in MTA and POA Failover Situations" on page
Failover of the Internet Agent itself is more complex. The various e-mail clients (POP3, IMAP4,
and LDAP) receive an error message when the server they were connected to becomes unavailable.
Most of the clients do not attempt to reconnect automatically, so the user must exit the e-mail client
and restart it to reestablish the connection after the failover process is complete. Fortunately, the
Internet Agent restarts quickly in its failover location so users can reconnect quickly.
As with the MTA and the POA, manual migration of the Internet Agent takes longer than failover. In
fact, the Internet Agent can seem especially slow to shut down properly, as it finishes its normal
processing and stops its threads. For a busy Internet Agent, you might need to wait several minutes
for it to shut down properly when you are manually migrating it.
