Description Per Steinar Iversen 2004-09-14 09:15:34 UTC 
From Bugzilla Helper:
User-Agent: Mozilla/5.0 (X11; U; Linux i686; en-US; rv:1.7.2)
Gecko/20040803

Description of problem:
It is possible to reliably block mail/spam from open http proxies by
adding this lines to the sendmail configuration:

APPENDDEF(`conf_sendmail_ENVDEF', `-D_FFR_BLOCK_PROXIES')

This then causes sendmail to block any smtp session that uses POST,
CONNECT etc. A typical log entry looks like this:

[218.12.171.14]: probable open proxy: command=POST / HTTP/1.0\r\n



Version-Release number of selected component (if applicable):
sendmail-8.13.1-2

How reproducible:
Always

Steps to Reproduce:
1. Receive spam from open http proxy
2.
3.
    

Actual Results:  Spam received

Expected Results:  It could be blocked...

Additional info:

It is hard to believe that email from http proxies is used for
anything but spamming.

I'm also interested in having this feature enabled per default...*narf*
Bugzilla is believing, I'm adding the keyword FutureFeature.
Comment 2 Thomas Woerner 2007-07-23 09:29:07 UTC 
The support for _FFR_BLOCK_PROXIES has been dropped by sendmail.

Closing as CANTFIX.
