Yes, that's how Tbird requests a read receipt.
You would use something like:
/etc/postfix/main.cf:
smtpd_command_filter = pcre:/etc/postfix/command_filter
/etc/postfix/command_filter:
# remove return receipt requests for example.com
if /example\.com/
/^(RCPT\s+TO:\s*<.*>.*)\s+NOTIFY=\S+(.*)/ $1 $2
endif
The above is based on the examples given in
http://www.postfix.org/postconf.5.html#smtpd_command_filter
