So avoid inetd. tcpserver does the job very well.

sendmail is not such a good example to quote for anything, especially this

No, but a run script for using tcpserver would be something like:

#! /bin/sh
exec 2>&1
exec tcpserver \
 -c 100 \
 -u 0 -g 0\
 -l 0 \
 -HDRP \
 0 143 \
 /usr/local/libexec/dovecot/imap-login
