I am using greylisting only for cases where something looks suspicious (no Reverse DNS, no TLS, DNSBL, ...), so most non-spam emails go through without delay. And there are still some spam senders who don't seem to retry (and if they to retry, the delay might also help get better data from DNSBLs).
