Subject: [Spambayes] not getting my email
Message-ID: <CAF64id5wNsUEZc66HskBb_y=xaUDTFO00RWt5tS9oTy41hQO8A@mail.gmail.com>

When my email server get an email, if Procmail processes the email before
Spambayes does, then the email is delivered to a sub-folder on my IMAP server.
However, if it does go directly through Spambayes, then it is lost and I get the
following error message in the logs.


/usr/bin/python,/usr/local/cutedge/spambayes/sb_filter.py,-f,-p,/usr/local/cutedge/spambayes/hammiedb.pck"
Exception UnboundLocalError: "local variable 'fp' referenced before
assignment" in <bound method HammieFilter.close of
<__main__.HammieFilter object at 0x1016e90d0>> ignored

I have searched online but did not find anything that is
helpful. I think the emails are being lost because of the error.

Message-ID: <4959FF403F010B439FA817D51B0F169F640F5B@SYMCONSVR.symconinc.main>

Hello,

My spambayes is not working properly. 

1.      I cannot get the "Delete As Spam" button to appear. Only the
"Spambayes" button shows and nothing happen when I click it or on the
drop down arrow on the button. See below.

	
	 	 


2.      I cannot uninstall old SB version or install a new SB version.
By versions I mean SB 1.0.4 or 1.1a6. 

 

3.      Which version of SB is the latest and most stable? 

 

4.      The software does not run for other users. The configuration
wizard does not pop up when outlook is opened. I will it I logon as
Administrator Only.

 

5.      Please help, I am being swamped by thousands of e-mails

 

 

 

 

1.0.4

1.1a6

*	OS = XP
*	Outlook = 2003
*	The version of SpamBayes = 1.0.4 or 1.1a6.
*	Any log files or traceback. = Where do I find these?

 

 

Thank You

No solution, certainly not without knowing exactly why gocr croaked.  The
simplest workaround I can think of is to disable OCR scanning of embedded
images.

If you know what image it crashed on, can you send it to me?

Jeff,

I should have been more explicit in my response.  In your SpamBayes config
file set the x-crack_images configuration parameter to False.

I have a 64-bit Windows 7 laptop running Outlook 2010.  I have enabled
Spambayes.  It is moving junk email to the 'Junk Suspects' folder as it
should.  However, it is moving good emails to an unknown location.

 

1.        How can I find out where it is moving the good emails?

 

2.       How can I fix it?

 

 

Thanks.

Therein lies your problem.  I believe 64-bit Windows + Outlook + SpamBayes
is a problematic configuration.  The only workaround I have heard is to not
install SpamBayes in the default Program Files folder on C:.  Install it
on another (non-system?) disk and see if that helps.

(Not being a Windows person) I don't have answers to either of these
questions.  Perhaps someone else has some suggestions.

A Question for you.

I have the current version of Spambays and I?m running Windows XP.

Every time I start Outlook (my email program) my system does 1.6 million
reads to my hard drive prior to reading my email from the server.

Without Spambays this does not happen.

Any ideas why?

Thanks

I don't know.  You'll have to ask the author.  I believe you can find him

You maybe have inadvertently removed it.  Check the SpamBayes FAQ:

Message-ID: <FFED7107056D6C478ADC1C9EF7F4823608EFB6D7@mail2.network.com>

I had 1.0.4 installed at the time our computers were upgraded from
Office 2007 to Office 2010. The first time I ran Outlook after the
upgrade, it disabled SpamBayes because of an error (the same error that
I've seen mentioned in other postings on the web), so I upgraded to
1.1a6. After re-enabling SpamBayes, I restarted Outlook, and it showed
an error message stating that the SpamBayes plug-in is not working and
that I should restart Outlook to try again. Restarting Outlook only
resulted in the same error message, so I simply made SpamBayes inactive
and restarted Outlook. The error message went away, but now I have no
working SpamBayes. I'm running 32-bit Outlook 2010 on 64-bit Windows 7
Enterprise.

Is there going to be another release, soon, that I can try out to see if
it's fixed?

There's nobody around to do a release.  We have heard reports that the
installation on the system disk might be a problem on Windows 7.  Can you
try uninstalling it and then reinstalling it on another drive?  If so, let
us know if that helps or not.

Some have also reported success just by installing in an alternate

No, you cannot use SpamBayes with web based email services.
I wouldn't bother, Gmail's spam filter is already really good.

If your web based email provider also supports POP and/or IMAP then please
take a look at these FAQs:

I switched from comcast.net and Outlook with SpamBayes to gmail several
years ago.  I get much less spam now than I did then.  Gmail's spam filter
does a better job, because you have hundreds of millions of users training
it instead of just you.  I maintained SpamBayes, Outlook and comcast for
another few years for my tech-phobic wife.  I finally got her to switch to
gmail and dropped the whole PC mess.  She is much happier as well.

It is easy to create a gmail account and set it up to POP email from your
old address, so your old one still works with a few-minute delay before
GMail's next POP request.  I set up a Gmail filter to add a "ComCast" label
to all that email.  Every so often, I notify people I care about of my new
address, change it on registered websites and so forth.  It works quite
well, and only a few mails come through with a ComCast label anymore.

Disclaimer:  I work for Google, but not on GMail.  I started working for
Google after I made the switch, but before I switched my wife.

I'd be interested to see any references you might have about the technology
behind Gmail's spam filter.  I found this:

  http://mail.google.com/mail/help/intl/en/fightspam/spamexplained.html

That suggests user input is a key component to their spam technology, but
they say nothing about how they use it.  There is also clearly a personal
component in there somewhere.  It can't just be the wisdom of the crowd.  I
suspect input from Gmail users is just one component of the overall
decision-making process.  In SpamBayes parlance, user input might just be
another synthetic token to be consumed by a probabilistic classifier.

To support that contention I offer one anecdote and one hypothetical
scenario.

Anecdote: My wife and I both use Gmail.  From time-to-time I send her stuff
I think she might find interesting.  The other day I asked if she'd seen one
of these messages.  She hadn't.

  Skip: Have you checked your spam?
  Ellen: I never look at my spam.

I looked at her spam and found five messages from me over the previous week
or two.  My guess is that she checked off a bunch of messages in her inbox,
including one from me, and accidentally poked the Spam button instead of the
adjacent Delete button.  From her perspective, they appear to work about the
same.  Messages disappear from her inbox.  Still, she was telling Gmail that
my message was spam, and it responded accordingly.  On the flip side, while
I can believe that some people on the net don't like mail I send, I doubt
there are enough people saying my mails are spam to make a random email I
send to some other Gmail user classified as spam without further input from
that user.

Hypothetical scenario: 99.99% of the male Gmail-reading population probably
aren't interested in "be better in bed" mails and classify any which slip
through as spam, but there is that 0.01% who do find such mails very
interesting.  If nobody thought they were interesting, the spammers wouldn't
make any money off them and stop sending them).  If, on the other hand, that
0.01% fraction say, "hey, that ain't spam, that's good stuff!", then Gmail
probably responds very accurately to their preferences.  It has to respond
on a personalized basis, and I think this has to be the largest
consideration, more than the 99.99% of the male Gmail population saying they
are perfectly happy with their performance in bed, thank you very much.
Otherwise, such individual preferences could never override the wisdom of
the crowd.
