is there any Postfix configuration parameter to set the text Postfix shows to 
the sender when Connection concurrency limit is exceeded ???
Currently the sender (192.168.3.7) receives this:
    "421 4.7.0 labpot.local Error: too many connections from 192.168.3.7"
any way to change the text "too many connections from 192.168.3.7"  ???

You mean DELETE the "421 4.7.0 labpot.local Error:" portion and
only send "too many connections from 192.168.3.7"? That would not
be a valid response.

I guess he wants to replace the "too many connections from" with customized
text.

this seems to be hardcoded in sources and I think it's not wise to replace
it.

however it can be enhanced with smtpd_reject_footer e.g. to provide
localized message:
