We can use the following script to re install spamassassin on the server.
/scripts/perlinstaller –force Mail::Spamassassin
If the above script is giving errors, do the following steps:
export unset PERL5LIB unset PERL_LOCAL_LIB_ROOT rm /usr/bin/spamd rm /usr/bin/spamc /scripts/installspam –force /scripts/perlinstaller –force Mail::SpamAssassin
