Hi
And then there are ...... the point is if I were to
have deleted mails like that I would be in trouble. A major ISP overhere got
it's mailserver listed in several blacklists. That's cleared up by now but for a
while we had A LOT of false positives that even reached my hold weight in
declude. I had to requeue them using spamreview. Some of them were important,
students abroad that needed to communicate with a staf member.
So it depends. I have a layerd system using
declude:
no spam, no action
maybe spam, mark subject line including scored
points
probably spam: mark subject line including scored
points and hold for review
"centainly" spam: delete
If a false positive ever hits the last group.... to
bad, but the chances of that are very slim.
So deleting in IMail after hitting X listS... ok,
but X better be large enough. This ISP was listed in 4 black lists.
Met vriendelijke

Subject: Re: [IMail Forum] Trusted DNS
Black Lists (immediate deletion)
The guy said "Trusted DNS Black Lists" with
an "S" And as we all know, Imail is set up to delete immediately after
"X" amount of matches. Flagging every email and sending it to the spam
box is not a very good solution. There are people that get 2,000 spams a day.
They don't need to weed through the ones on 2 or 3 blacklists. What is the
point?

Black Lists (immediate deletion)
I too would suggest that there is no list that should
be trusted for immediate deletion. EVERY LIST OUT THERE will give you
false positives sometimes. If you only use Imail's filtering (IOW, if
you don't use a third-party spam filtering app), the best thing to do to
avoid false positives is to just flag the email with a header and use Imail
rules to reroute flagged messages to a spam mailbox (as was previously
suggested, I believe). Even if you are OK with the occasional false
positives, I STILL wouldn't delete based on a single test. Don't
delete unless it matches 2 tests. You'll still delete some
false-positives, but not as many.

Well no I do not know what he ment and I do not know his expertise
level so I am going to give the most consertive advise. Mabe he thinks it
is OK do delete on a single test. If we do that here our customers have
the potential to loose customers bu deleting mail when spamcops automated
system blocks yahoo or wanadoo.fr for a few hours.
I think it is bad advise to reccomend to any one to delete on a
single test unless that test is completely controlled by the mail server
administrator.
Just this past weekend I had 5 business emails flaged as spam by
CBL that were delisted by the time I checked to see why the were listed.
If I deleted on just that one test then the buseness would have been lost
the emails were from potential customers. That just happen to be on the
same ISP mail server.

You know what he meant. We all know we live
in an imperfect world.
There are no lists that can be trusted, unless you create your
own DNS black list. All lists make mistakes and list servers
temporarily that should not be listed.

Hello All,
Off-late we have been receiving a lot of
SPAMs. At present, the spam settings are to tag the subject line and
deliver to the user.
Can anyone suggest "Trusted DNS
Black Lists (immediate deletion)" ?
Thanks and Regards,
