Need help please!
I have activated the SPAMHAUS BLACKLIST on our domino 6 SMTP server. However now we are getting nearly 80% of our external mail blocked.
As an example this ip address 204.128.175.2 (mx1.powerisp.com) is rejected. But when I go to SPAMHAUS and check that IP address in their IP lookup it does not register as being listed in their blacklist.
Is there something I am doing wrong on the server side?
Subject: Blacklist SPAMHAUS
You should add to the server configuration
DNS Blacklist sites: sbl.spamhaus.org; bl.spamcop.net
spamcop is the best as you can also set up a script to report to abusereport@spamabuse.org from a spam deposit database (we have a central one for everyone that I have created) then a agent generates the report and issues to spamcop.
A delivery failure to spamabuse@yourdomain
temp stops the agent, just incase there mail box is full. i.e spam report db has an agent that checks for failure reports if so then notifies admin and stops.
You must include header info for the report email… i.e
A small extract, not complete, of how to retrieve the header info (not all but enough for spamcop)
Dim s As New NotesSession
Dim doc As Notesdocument
Dim MIME As NotesMimeEntity
s.ConvertMime = False
’ ADD CODE HERE TO ASSIGNED DOC could be from dc or from uiview, etc…
Set MIME = doc.GetMIMEEntity(“Body”)
If Not(mime Is Nothing) Then
Dim filters(11) As String
filters(0) = “Subject”
filters(1) = “Received”
filters(2) = “Message-ID”
filters(3) = “Reply-To”
filters(4) = “Date”
filters(5) = “From”
filters(6) = “To”
filters(7) = “Cc”
filters(8) = “Bcc”
filters(9) = “Content-Type”
filters(10) = “X-Mailer”
If doc.MIMEHeader(0) = “” Then
doc.MIMEHeader = mime.GetSomeHeaders(filters, True)
s.ConvertMime = True
Subject: Check spelling of zone name
Steve Linford posted to NANAE about this a while back. Google does not have the original post but it is quoted in full in this post.
Basically, Spamhaus will respond with a hit for every IP address if the zone name used is one of the common misspellings. This is an incentive to people to use correct zone names and keep useless DNS queries away from the Spamhaus name servers.
