smtpd: mail stuck in queue

[Alexander Hall]

Hi,

I noticed a box of mine having had a misconfigured mail relay, resulting 
in lots of mail queuing up. Now, after fixing the configuration, new 
mail are properly sent.

However, it seems the invalid 'mta-relay' setting, as seen in the 
envelopes of the queued mail does not get revised while issuing 'smtpctl 
schedule ...'. Thus, the old mail stays in the queue.

Any pointers on how to proceed is appreciated, possibly including 
cluesticks as of why the observed behaviour might be the proper one.
