That's possible with the fast flush introduced in one of the recent
snapshots -- ETRN only flushes the queue for the domain given as
argument to the ETRN command.
You could use "fetchmail" to issue an "ETRN yourinternal.domain" to the
postfix server to flush internal mail only.
% postfix flush
would flush all mail.

BTW, this calls for a feature:

% postfix flush
flushes all mail

% postfix flush domain.com
flushes mail with the destination of domain.com

% postfix flush .domain.com
flushes mail with the destination of domain.com's subdomains

% postfix flush !domain.com
flushes all mail except for mail with the destination of domain.com
