Bear in mind that MySQL with InnoDB (as well PostgreSQL) offer
fine-grained locking at a record level, which SQLite does not
(the last time I checked). It is very likely that SpamAssassin
could use SQLite as user preferences database (i.e. read-only)
with no problems, it is also very likely that the usage of
SQLite for a r/w database such as Bayes and AWL will cause
lock contention on a busy server.
