    Keep in mind that a steady, constant flow of e-mail traffic, depending upon
    the configuration of the originating MTA, could show a steady increase in
    the number of connections, since a transient SMTP error will result in
    periodic retries.
    
    It almost sounds like some spammers got ahold of an "open relay" list that
    indicated (incorrectly, apparently) that this IP address was an open relay.
