I must assume you can use PICO, and a shell etc? You really need to share more details so others can help you.
Delete the db in
/home/e-smith/db/spamassassin
add to the whitelist/blacklist or subtract, use the EXACT spacing and capitalization shown below, use TEXT EDIT (or an editor which does not insert bogus line wraps) and place input on one line without wrapping...
/sbin/e-smith/db spamassassin setprop wbl.global foo@bar.com White foobar@bar.net Black *@*easymoney.net White
expand-template /etc/mail/spamassassin/local.cf
svc -t /service/spamd
verify by looking at /etc/mail/spamassassin/local.cf
This again assume some level of proficiency navigating the system. Hope this helps.
