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...
