With next passdb{} as 1st in chain:

passdb {
  driver = checkpassword
  args = "/tmp/chktst ip=%r service=%s"
  result_success = continue
  result_failure = return-fail
}

and this script
BEGIN /tmp/chktst
#!/bin/bash

echo "$@" >>/tmp/chktst.log
# return OK
exit 0
# return FAIL
exit 1
END

I get the log entry:
ip=127.0.0.1 service=imap
/usr/local/dovecot-2.2.15/libexec/dovecot/checkpassword-reply

and with exit 0, the next passdb{} let me login, and with exit 1, all
logins fail.

So, with the current stock Dovecot you can make RBL calls and
decissions with a script. ;-)
