Try downloading qmhandle from qmail.org. It's a Perl script that automates
the entire process for you, and you don't have to run queue fix
The queue fix script is almost never needed unless the admin has been
playing around in the queue manually.

Only if you use multilog (part of daemontools). If you use syslog, then
the timestamps are perfectly human-readable.

I've never needed anything more than grep or less to search qmail's logs.

I hardly find it that difficult to download one Perl script.

If you think it's hard to manage qmail's queue and search its logs, then
that's your opionion. The FUD was labelling it "the Windows of MTAs"
without giving any specifics.
