Thanks. Could someone please let me know what I
have to do to prevent blacklisting the IP address of the server? Such as
domain keys, SPF record, so on.

Authenticated users are trusted to not send spam, so preventing outbound
spam from QMT is limited to being sure that it's not configured to be an
open relay (the default configuration), and protecting login credentials.
The later can be difficult depending on users, but you should be ensure
that no clients are configured to send passwords in clear text (TLS/SSL is
recommended for all connections). This can be inforced with dovecot
(recommended over the stock courier), but there is no enforcement
mechanism for outbound connections.
Your best defense against inbound spam is to use spamdyke. After that,
some tuning of spamassassin (adjusting scoring, etc) might be helpful.
Keyword filtering is typically not an effective way to fight spam.
HTH.
