    Blacklists aren't working

    My Mercury 4.80 server is not blocking any connections using the defined blacklists. From the mail server, I can take the IP address and do an nslookup from the command prompt on the server and get a positive response so I don't think it is a firewall issue. I am pasting my blacklist definition and MercuryS section from my mecury,ini file. Looking for any ideas on how to troubleshoot this. 

    -jeff 

    C:\Users\admin>nslookup 107.253.227.45.bl.spamcop.net
    Server:  google-public-dns-a.google.com
    Address:  8.8.8.8

    Non-authoritative answer:
    Name:    107.253.227.45.bl.spamcop.net
    Address:  127.0.0.2

    Below is the blacklist definition from the MS_SPAM.MER file.

    Begin
    Name: Spamcop
    Enabled: Y
    QueryType: Blacklist
    QueryForm: Address
    Hostname: bl.spamcop.net
    Strictness: Normal
    Action: Drop
    Parameter: Your IP Address is Blacklisted on http://www.spamcop.net
    End

    Here is the MercuryS section from my mercury.ini file:

    Re: Blacklists aren't working

    I'm not using DNSBL queries directly from Mercury myself, but I haven't seen any recent reports of such problems.

    If multiple name servers are specified you could verify that all work by including the server IP address in nslookup, for instance:

        nslookup 107.253.227.45.bl.spamcop.net 8.8.4.4

    If all respond correctly the next step could be to try it with the current beta version of Mercury, which has quite a lot of updates in the networking code. Post here and I'll provide a download link.

    Re: Blacklists aren't working

    Hello jeffn,

    Blacklists are working for me. I use Spamhaus lists MS_SPAM.MER:-

    Begin
    Name: Spamhaus ZEN
    Enabled: Y
    QueryType: Blacklist
    QueryForm: Address
    Hostname: zen.spamhaus.org
    Strictness: Range 127.0.0.2 - 127.0.0.11
    Action: Reject
    Parameter: Message Rejected - Matched SPAMHAUS ZEN
    End

    Begin
    Name: Spamhaus DBL
    Enabled: Y
    QueryType: Blacklist
    QueryForm: Domain
    Hostname: dbl.spamhaus.org
    Strictness: Range 127.0.1.2 - 127.0.1.255
    Action: Reject
    Parameter: Message Rejected - Matched SPAMHAUS DBL
    End

     

    Has Spamcop changed their result codes recently?

    John.
