how can I remove "Operation timed out" messages from mail queue with
smtpctl(8)? I have default setup for local delivery and I tested if
it's possible to send emails to outside world as with default
sendmail(8) configuration in OpenBSD. Now I have two messages in
queue. I read man pages for smtpd(8), smtpctl(8) and smtpd.conf(5) and
there is nothing about that. Is it safe to remove those files directly
from /var/spool/smtpd/queue ?
it is safe if you shutdown smtpd prior to removing the files, but if you
leave a message directory or a message file and no envelope, i'd bet some
fatal() will trigger at some point.
don't play with the queue using your shell unless you know how smtpd is
