deleting messages from the queue

[wolfgang zeikat]

i have a few messages sitting in the qmail queue that will never get
delivered - for example because the recipients' addies are on
fully-unqualified hosts.

can i just delete those messages to save qmail the retries and to save me
the final "sorry wasn't able to deliver" mail to postmaster@ ? or do i
have to follow some special steps to do so?
