I've noticed most of the compromised accounts are exploited from
"elsewhere".  I'm sorry if this rule is US centric, but it appears to work,
somewhat, for me:

header        RELAY_NOT_US    X-Relay-Countries =~
/\b[ABCDEFGHIJKLMNOPQRTVWXYZ]{2}\b/
describe    RELAY_NOT_US    Relayed though any country other than the US
score        RELAY_NOT_US    0.01

meta        AE_FOREIGN_FREE    FREEMAIL_FROM && RELAY_NOT_US
describe    AE_FOREIGN_FREE    Freemail that originated somewhere other than
the US
score        AE_FOREIGN_FREE    0.5

meta         AE_SHORT_FREE    FREEMAIL_FROM && (URIBL_DBL_SHORT ||
URIBL_SU_JMF)
describe    AE_SHORT_FREE    has shortened URL from a freemail account
