The URL is no longer valid, can you post a sample message to this webpage or 
close this ticket?

Subject: Re:  blacklist check fails with special character

When I originally submitted the bug report I included a URL:
http://mike.passwall.com/sa/bug1.eml

That URL is still valid and functional. I have checked from 3 different
locations and each is able to load the page. (Colocation facility, home,
and a local uni.)

That URL contains the message that did not get marked as spam by 2.60 when
the domain (dq07.net) was blacklisted with:
blacklist_from *@*.dq07.net
and
blacklist_from *@dq07.net

However, messages prior to this one and after this one were marked as
spam. The only obvious difference appears to be the '}' in the username
field.

Does this page not load for you?

Also, I am on 2.62 now. That was reported when I was on 2.60

Please let me know if there is more information that can help you.

My inability to load this page was a bug in Outlook Express / Internet 
Explorer, when I click your like I get:
mhtml:http://mike.passwall.com/sa/bug1.eml
And a standard IE error page about page not available, blah blah.  I seen this 
eariler but didn't notice my systems were changing the URL after I click the 
link.. my bad!

Subject: Re:  blacklist check fails with special character

Sounds like a client-side OS application/OS processing of the message by
MIME-type/extention.

I have duplicated the file and made it available with a ".txt" extention
so now these two URL offer file with the same contents:

http://mike.passwall.com/sa/bug1.eml
http://mike.passwall.com/sa/bug1.txt

The .txt should allow nearly all browsers to show the message contents
without problem.

If the From: header contains a punctuation character immediately prior to the @
character in the email address, the blacklist mechanism breaks down.  For
example, assume the user has:

    blacklist_from *@world.std.com

If sent mail with a From address of something like:

    a?@world.std.com

the message won't be marked with USER_IN_BLACKLIST:

>From phanson@well.com  Mon Mar 29 00:24:50 2004Return-Path: <phanson@well.com>
>Date: Mon, 29 Mar 2004 00:24:49 -0800 (PST)

If the punctuation character is not the last character prior to the @, the
blacklist mechanism appears to work:

>From phanson@well.com  Mon Mar 29 00:24:40 2004
>Return-Path: <phanson@well.com>

The precise character used doesn't seem to matter - if it isn't alphanumeric, a
hyphen, or an underscore, SA seems to get confused.

more accuracy and performance bugs going to 3.1.0 milestone

I can't reproduce this in the 3.0 code.  if it's still an issue for you, we can reopen the ticket.
