No. A default qmail/tcpserver installation can do 20 local
deliveries, 20 remote deliveries, and 40 incoming SMTP sessions. The
local and remote concurrencies can be raised to 120 by reconfiguration
and to 255 by adjusting "conf-spawn" and recompiling. There are
patches to raise that even higher, and multiple independent qmail
installations on the same system can also be used.

Delivery concurrency is one per message plus one or more queue
runners. Incoming concurrency is limited only by system resources,
load average, and inetd's connection rate limit.

Don't know.

50 processes total (incoming+outgoing+daemons+local deliveries). Upper
limit is determined by system resources.

Don't know.
