You misread.

What they said was that if you are checking through crontab, you should 
have it check no more than once per hour, and only on minutes 3 through 
57, excluding 10,20,30,40,50.

You are actually now worse than before.  You were checking far *less* 
than once an hour, so you were fine, and would never have been 
blacklisted.  Now, however, you might actually, since you are more than 
once an hour.

I check 8 times a day (the freshclam.conf option "Checks" should really 
have been an interval between checks, but it is instead the number of 
checks per day), or every 3 hours, plus use the "DNSDatabaseInfo" 
option, since that is on by default in the RPM I use.


I think we are all just a bit lost or none of us has mastered reading
comprehension. This is a slam on all of us, me included, since I'm now
foggy, maybe I'm a flip flopper :)

>From the site:
"Unless you are using DNSDatabaseInfo, please keep the check frequency below
once per hour. "  

This here states that my initial read was in fact correct. If your not using
DNSDatabaseInfo (if you are in fact pre 8.0), then please check for updates
less then once per hour.

Which means that those (me included) that were checking 4-8 times a day, are
actually bad mimedefang citizens.

1) if you run freshclam from crontab, check that you have an entry like the
following:  
 
N * * * * /usr/local/bin/freshclam --quiet  

It also clearly cites that "Unless you are using DNSDatabaseInfo, please
keep the check frequency below once per hour." Which is in line with this
thread. If your running 8.0 and have DNSDatabaseInfo turned on, check it
whenever you want and this thread really has no impact on you, it only
concerns those that are not running the latest, and or have not enabled
DNSDatabaseInfo (since it is NOT on by default).
 
That clearly shows a crontab that is running N times an hour or every N
minutes, and does not cite N times per day.
