Re: [Declude.JunkMail] [IMail Forum] Cannot receive messages from Comcast.net accounts from Comcast.net accountsComcast.net accounts from Comcast.net accounts

[Matthew Bramble]

I've found that automated mail including opt-in newsletters, E-commerce 
receipts, and product notifications, and renewal notices commonly fail 
the BADHEADERS, SPAMHEADERS and HELOBOGUS tests.   For example, Network 
Solutions' own renewal notices were being caught by SPAMHEADERS back in 
March (the last time one came to me).  This is also a big issue with 
many of the auto dealers using my service as their E-mail inquiries from 
the manufacturer sites typically fail at least one of the above tests.  
It's sad that these folks can't construct a valid E-mail header, but my 
customers consider this to be my problem.

I rely on a combination of tests with the exception of a few blacklists 
that I trust (like SpamCop).  I tune the tests so that the poorly 
configured legitimate stuff gets through with one point to spare.  I 
would get deluged with complaints and lose business if I made things any 
more strict, and I'm still able to block around 97% of it, and my false 
reject rate is about 0.03%.

Here is the message that failed and why.  I know it is failing 
because of SpamHeaders.  How can I correct this without taking the 
hold off Spamheaders?  I need to get mail from comcast.com accounts.  
The spamheaders is blocking legitimate mail.


We do NOT recommend blocking E-mail that fails the SPAMHEADERS test 
(whereas we DO recommend blocking E-mail that fails the BADHEADERS 
test).  Lots of legitimate E-mail -- mostly from web sites that have 
their own poorly designed custom mailserver written by a company 
employee -- will fail the SPAMHEADERS test.

X-Mailer: AT&T Message Center Version 1 (Jul 22 2003)


If you would prefer for the sender to fix their problem, you would 
need to have them upgrade their AT&T Message Center software to the 
latest version (let's hope they have fixed the missing Message-ID: 
problem in the past month!).
