It worked flawlessly until the last version of sober hit it a couple of

You might want to set the ConnectionRateThrottle parameter in Sendmail
(confCONNECTION_RATE_THROTTLE in sendmail.mc) quite low, like to around 3.
That delays connections if more than 3/second come in.
For 40+ mail accounts? Set it to 1. Way more than enough. He probably
receives at most several emails per minute (if that much).
Also. Set number of slaves to something hardware can handle. Worst
case is, some email will get delayed when he gets hit. Usually, not
really a big deal. Make sure virus scanner runs first (ClamAV is
usually light weight enough not to kill machine), and that no filtering
is done if virus is detected (like it is done in default MD
configuration). No point in running SpamAssassin on something that is
going to be rejected anyhow...
