One of our user did something strange (and he wasn't available for comment,
as the press says), some kind of double loop, where each mail to him
would generate two replies (fresh ones, i.e. no way for qmail to detect
loops or to many hops) that would bounce, etc.
Anyhow, the queue was full of mails no one was ever going to read ( ~12'000
of them). What I did: kill qmail-send, remove info/nnn remote/nnn and *then*
mess/nnn (because of the i-node number trick) for each of those useless
messages. This took quite some time, but fairly early I noticed that
qmail-send was still alive, so I did a "kill -9" of it, but this means
that some messages were removed with qmail-send and children running.
(qmail-smtpd's were running all along, i.e. I didn't kill tcpserver).
How dangerous is this ? Apparently, it did no harm, which drives me
to ask: what manipulations of the queue are "safe" with qmail-send
and/or qmail-smtpd's running ? Any tips/URL's are welcome.
