    Posted: 23 July 2003 at 8:48pm

I'm trying to figure out how FROM blacklist works.

Put qq@hotmail.com in the local balcklist FROM list.

Send an email from qq@hotmail.com to SpamFilter.

Watched the activity log, it said:

........EmailFrom is in local blacklist file...

RCPT TO: xx@xxxx.xxx (for example)

Email from qq@hotmail.com to xx@xxxx.xxx was queued.

Sending email from qq@hotmail.com to xx@xxxx.xxx

Disconnect

Email from qq@hotmail.com to xx@xxxx.xxx was forwarded to mailserver02

How does this happen?? Why the FROM is in the local blacklist but still it gets through??

Thanks,

Danny,

Can you please post the full contents of the activity log, starting with the entry that shows the incoming connection being made to the one that shows it being forwarded? We'd also need a copy of your SpamFilter.ini file and a copy of your local black/white list files so we can try to replicate the problem. You can email them to support@logsat.com.

If an email is in the FROM blacklist, it should be blocked unless one of the whitelists is causing it to be delivered.

Danny,

Mystery solved... Under your "Settings" - "Customized Items" you do not have an error response for the "Response if FROM email is in local blacklist/empty". Since there is not an error defined to return to the sender, SpamFilter has no choice but to accept the email.

Please note that some other responses are empty as well. Those will also cause emails to not be rejected.

To restore the default error responses, simply close SpamFilter, find in the SpamFilter.ini file the following lines and delete them. Next time SpamFilter is started they will be recreated.

[Error Response]
ResponseBlacklistedMAPS=521 The IP %IP% is Blacklisted by %MAPSResponse%.
ResponseBlacklistLocalIP=
ResponseBlacklistLocalDomain=
ResponseBlacklistLocalEMail=
ResponseBlacklistLocalEMailTo=
ResponseNoReverseDNS=557 Your IP %IP% does not have a reverse DNS entry. Disconnecting...
ResponseMaxRCPTTO=557 You exceeded then maximum number of RCPT TO. Disconnecting...
ResponseCountryBlacklist=557 Your IP address is from a blacklisted country. Disconnecting..
ResponseRelayRestricted=557 You are not allowed to send mail to %EMailTo%
ResponseKeywordMatch=

Thank you so much, you are the best !!
 
However, what if say I do not want to send out any response when the message is rejected ? Is there anywhere I can find such an option??
 
Thanks again I love your program,

You could just output the numerric error code (500-somthing), that will do the trick. You could also send in theory just a period "." or some other meaningless characters, but we strongly recommend against not having a numeric error code since that violates RFC standards.
