Due to message volume, I'm considering rotating my mail logs daily at my
local time "midnight" and retaining about 30 days worth of files on
disk. I'd like to have the date in the file names so visually I'll know
what span is in each file.

Can this be done? (put dates into the file name)

Should this be done? (put the date into the file name)

If you're doing something like this already, how did you do it?

You need the dateext option in the logrotate config. That'll mean your
archives have the date extension, and the current one is just whatever
it's normally called, which I guess should be OK for you?

Never caused me any problems ;)

Sure, I do :-)

man logrotate → dateext

> Should this be done? (put the date into the file name)

Sure, I do in my "fetchmail" logs :-)

By defining "dateext" variable info the "logrotate" script.

***
dateext
Archive old versions of log files adding a daily extension like
YYYYMMDD instead of simply adding a number.

Depends. See the other posts about logrotate
> Should this be done? (put the date into the file name)
No clue

I am logging to syslog (the protocol) and replaced syslog (the package)
with syslog-ng. syslog-ng can be configured to do this:

destination df_syslog {
file("/var/log/$HOST/$YEAR/$MONTH/$DAY/syslog"
template("$ISODATE $HOST $MSG\n")
owner(root) group(root) perm(0600) dir_perm(0700) create_dirs(yes));
};

This is a snipped that configures a file in a directory-structure matching
the hostname and the date (you should be able to guess the details...)

http://www.syslog.org/syslog-ng/v2/ has some more examples.
