I finally figured it out!

I had to remove :null from *@[xxx.xxx.xxx.xxx]:null.
Somehow DnsReport got a 250 respons back when the mail was sent to null.
What is prefered when we add to the blacklist? should we use :null or not? I would like to send as little respons as possible back to the sender lol.

Thanks!

Thanks!

That worked, but now I get a more serious error. Is there any way to stop this?:

If you're using SpamFilter Enterprise, you can follow the screenshot at:
http://www.logsat.com/sfi-spam-filter-screenshots/sfi-more-filtering-options.asp
and add the domain:

[xxx.xxx.xxx.xxx]

in the list of domains.

If you're using SpamFilter ISP, in the screenshot above, the list of domains in the upper left corner of the window will not be there, while instead you will see a tab labeled "Local Domains". That is the list Desperafo refers to, where the domain [xxx.xxx.xxx.xxx] should be added.

For the "BlockedToEmail" list Desperado refers to, that is actually the tab labeled "TO Email" in the Blacklist group of tabs, and that is where you should add *@[xxx.xxx.xxx.xxx]:null]]> Wed, 18 Jun 2008 06:46:08 +0000 https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5691&PID=12166&title=nonrfccompliant#12166 <![CDATA[non-RFC-compliant? : Desperado wrote:Seeb, In...]]> https://www.logsat.com/spamfilter/forums/forum_posts.asp?TID=5691&PID=12165&title=nonrfccompliant#12165 Author: cwbrandsdal

DnsReport uses the "Literal" address form to test your mail server and this makes SpamFilter accept the literal but then null it.


We use the latest version of SpamFilter ISP, but can not find these lists.. Can anyone help uss on how to do this? We would like to have a clean dnsreport hehe

Thanks,

Thanks Desperado,

I do not need to see DnsReport test pass. I just noticed it reports such thing and wanted to ask if is that intended in SpamFilter and I got my answer ;)

SpamFilter is indeed forcefully terminating the connection from the remote server in some cases. This is not RFC compliant, as the RFC would like SpamFilter to simply output an error message to the remote server, allowing them to try again, and again and again... Until they get a correct recipient or a correct email.

The RFC is quite old in some sections, and they really need to update it to consider "spam" in the equation, as it was of no concern several years ago.

I do not believe we are going to follow the RFC strictly, and DNSReport has been advised that they should not consider those disconnect as "Errors" as they are by design.

Not sure, but I have noticed the same since using SF. Be interesting to know what the reason is.

May be due dnsreport only doing some sort of 'quick' check, rather than emulating what an actual SMTP server would really do, and therefore the two get a different responses from SF which dnsreport interprets as a problem.

Hello

I have another question - during tests of my domain from http://www.dnsreport.com page I received an error:

ERROR: I could not complete a connection to any of your mailservers!

xxx.xxxx.xxx: The mailserver terminated the connection before the transaction was complete (state 8). This is not RFC compliant, and therefore either due to an error, or it may be the result of a non-RFC-compliant mailserver or non-RFC-compliant anti-spam program.

Of course site was trying to connect to Spam Filter.

Is that correct?

regards

Seeb
