    Go on, have a guess
    Well, if you triggered the dictionary attack ACL, then he's sending to non-existent recipients, which is certainly something to be worried about.

    Apart from that, if you want to increase the hit rate, just change this:

    condition = ${if > {${eval:$rcpt_fail_count}}{3}{yes}{no}}

    to this:

    condition = ${if > {${eval:$rcpt_fail_count}}{29}{yes}{no}}

    in the dictionary attack ACL. However, increasing it to that sort of size will probably effectively disable the ACL from triggering anyway if the attack is being sent in batches.
