This may also be a result of slow DNS and/or IDENT lookups:
- you may use the -R switch to disable IDENT lookups (very much recommended,
as most systems do not provide reliable info anyway).
- you may use the -H switch to disable remote host name lookups.
This speeds up connections if DNS is slow or broken for the IPs
your customers come from. It also is useless if the IPs do not have
PTR records.
Please note that these settings may also be useful if you start
qmail-smtpd via tcpserver.

start your tcpserver with -v switch and direct its output to a logfile.
There you should see messages like
tcpserver: status: 2/150
That means that currently 2 out of 150 max tcpservers are active.
The max limit can be increased with -c<num>, default is 40.

No.
