mr.insister@nospam.com - 19 Apr 2005 19:59 GMT
I'm getting half a dozen spams a day selling pharmaceuticals of various
sorts and Eudora 6.2 will not recognize them as junk. In addition to the
random word strings that spammers put into emails, in these particular
ones the body contents always contain exactly the same advertisment,
right down to graphics, colors, font choices and language. What it seems
that Eudora restricts itself to looking at are the subject and sender
lines. Eudora has missed every spam (and I've marked dozens of them as
junk), all the while managing to transfer legit email to the junk
mailbox with abandon. Is there an email client out there for OSX 10.3.8
that can handle multiple accounts AND check the corpus of an email and
recognize features that you have specified as junk? Thanks for
responding.

They get through there too now, even when checking a SpamCop account!

I guess the spammers are getting smarter :-(

I use a SpamCop account with Mail.app, and SpamCop also has Spam
Assassin enabled. It doesn't let much through.

I use mail.app on three accounts, two pop accounts in my ISP's shell
account and my .mac account on the Web.

I have a friend on Comcast and he gets spam daily too.  It gets tiring
setting filters all the time when your ISP *should* be managing that for
you.  Is there something you need to do to engage Comcast filtering that
you have not done?  You are using a firewall, right?   OTOH, there isn't
much an ISP can do to protect you if you are advertising your email
address on the web or on usenet.  Even if you've only done it a few
times, it will haunt you for a very long time.

I have never had to set a single filter on Mail.app since I switched
over to my current ISP.

I am on comcast and if they have filtering I've never heard about it. Do
you have more info on this? I use the OSX firewall but don't have any
rules established. I don't know if it filters for content. I'm very
circumspect about where I park my email address but it only takes one
disreputable dealer to get the ball rolling. I have set up several dummy
email accounts on comcast which I have not used once just to see if they
would get spam and they did.

They've had Brightmail spam filtering for a long time.  Login to
www.comcast.net, click on "My Account", and then click on "Enable or
disable spam filters".

ISPs are best used for what they are good at - providing
connectivity.

You want good mail service, use a specialist mail service
provider, not your ISP.  I recommend Fastmail.FM, but there
are others which are also excellent.

One shouldn't have to set much in the way of filters for
Mail.app anyway.  It's got built-in learning systems to
recognize spam on its own.  All one has to do is when one
sees spam in one's inbox, hit the "this is spam" button.
Over time, it gets quite good at detecting spam.

Telephone companies provide good connectivity as well but we do not
expect the phone to ring every time some jerk wants to mass advertise
the latest mortgage or drug deal.  A good ISP that offers email with its
service should also provide a measure of security against those kinds of
spammers but the customer also has a responsibility to not post his
address all over the internet.  It's quite simple really.  When given a
choice, users will opt for more security as long as the prices are
comparable.  Perhaps some cable companies like Comcast don't provide
reasonable protection because they have a monopoly on the local cable
market.  They only do what they have to do.

The nearest cable provider where I live charges $80. a month for *basic*
service.  (You cannot get just internet)  How many people can afford to
pay that and then have to get a separate email (or Usenet) provider as
well?  Sorry, but I think your idea is unrealistic for most people.

I use 'SpamFire' (http://www.matterform.com/?page=spamfire/), which
works very well. It's not an email program, but sits between the mail
server and your email program. It gets your mail, filters all spam and
sends the rest to your regular email program, so you can keep using
Eudora.

A goodly proportion of those pharmaceuticals spams use a MIME-encoded
GIF or JPG image do deliver the actual content, so that there isn't a
whole lot in the text body of the spam to subject to the kind of
content filtering used in many "spam recognition" applications.  Have
a look at the raw email content to see if this is the case with the
ones getting through.  You may need to implement a filter which diverts
such emails if you don't want to see them.

And SpamAssassin recognizes that a mail message with nothing
but gibberish text and an inline (or externally linked) image
is probably spam.  It's amazingly good at it.

You seem not to have had a look at SpamSieve - it's quite good at
peeking inside the usual tricks, and sometimes exactly the measures
taken to hide content trip its filter - it does work on the whole
message, including all MIME content and all headers.
Plus it uses sound mathematical calculation of real probabilities, based
on your good e-mail - something a spammer cannot possibly know and makes
each individuals filter different, therefore hard to circumvent.
But have a look at it, the evaluation is free - and see for yourself.

I checked and they are MIME-encoded. If you don't mind one more
response, where and how would I implement such a filter? OSX's firewall?
Third party spam catchers? I can't see any such capability in my
searches through Eudora's preference settings.

By all means have a look at http://c-command.com/spamsieve/

Some of the content that trips my filter:

Word  Spam  Good  Total Prob. Last Used
to:webmaster@  1909  0  1909  1.000 04/20/05
R:^78^131   1064  0  1064  1.000 04/20/05
XM:MicrosoftOutlookExpress6.00.2462.0000  472   0  472   1.000 04/18/05
U:h   444   0  444   1.000 04/20/05

^fg-ff00ff  240   0  240   1.000 02/14/05

All you have to give it is a few hundred good and bad messages marked as
such.
Afterwards you only tell it if it goes wrong.

That's it.

My current statistics for this year are 126 Spam messages per day, 90%
Spam, 0 false positives, 0 false negatives.

I'm using Netscape 7.2 which is not listed on the spamsieve
website as supported. Can Spamsieve be run with Netscape 7.2?

Also, Netscape has a filter that seems to be intended to function
similar to how Spamsieve is described to function but after
hundreds of markings, I still occasionally get goodmail showing
up in the junk folder. Unfortunately, all of them have been
important mail so I'm constantly forced to always scan the stupid
junk mail folder looking for needles in the haystack since there
is so much "hay". I would like to know if Spamsieve is really
that much better or not.

Your main filter should be "anything which isn't 'to' or 'cc' to me is
spam, unless I know the source."  Then add filters for mailing lists.
