  Hi there litmic,,,,

As long as  it is a cluster the configuration of the two servers must be similar . However, what I recommend over here is to compare the server , configuration , and connection documents of both servers and make sure that they are identical . Then you can but server A down and see if SMTP is working on serverB or not .

are you talking inbound SMTP traffic?

for inbound, you can set  MX records to point to both A & B servers with equal weight

For outbound, you can list both server host names in "Relay host for messages leaving the local internet domain:" in the server configuration document, separated by semicolon

Yea, it's easy to redirect to B when A is down.

As fgrushevsky mentioned, you can configure your MX records in your DNS to redirect to B.

Server A MX 10
Server B MX 20

So, if A is down then inbound smtp is redirected over Server B, which is MX 20 (lower priority)

Also, I sometimes like to watch SMTP traffic by issuing the set config smtpdebuio at the console.

SMTPDebugIO

Applies to: Servers       Enables the logging of all data sent and received by the SMTP task. Logging is cumulative; each level provides all information as described for previous levels when value is greater than 1.
0 (default) - No logging of I/O
1 - Number of bytes sent and received during various stages of SMTP conversation
3 - Logs all data received by the SMTP task, including SMTP commands received and responses sent
4 - RFC822 data (message data)

Use SMTPDebugIO only when necessary and disable it again as soon as possible. It can cause the log file to grow very large, and logs the contents of received messages.
