Me too. I use only:
dns-blacklist-entry=zen.spamhaus.org
dns-blacklist-entry=bl.spamcop.net

These have *very* few FPs.

I've been running w/out graylisting lately. It doesn't seem to be all 
that effective on top of spamdyke's other filters, and the delays can be 
annoying at times.

That's doubtful. Install the latest version in the same way the current 
one was done. Note, you'll need to review your configuration settings if 
you're upgrading from a pre-4.x release, as there are some 
incompatibilities between major releases.

Configuration directories are not exactly simple, and I try to avoid 
them at pretty much all costs (I still don't use them). I think you'll 
be better off identifying the RBL that's rejecting yahoo addresses, and 
discontinue using that, as Gary suggested.

Some RBLs block yahoo because spammers really love to use it. I feel that this is way too aggressive and any blacklist that blocks like this I avoid. However, I do have yahoo in my rdns whitelist anyway since I use that to avoid putting things on the graylist. This way I can use the graylist more effectively to see if my spamdyke rejection strategy is working well.GaryOn Sep 16, 2012 6:02 PM, emailitis.com  wrote: Thank you Sam for your speedy response.  How can I tell if I have the latest version?  Can you tell me what shell command to run?  And to update, is it simply “yum upgrade spamdyke”? I do not want to whitelist the whole btinternet.com domain as there will be Spam.  I really like your idea to “use a configuration directory to whitelist any sender within btinternet.com when the rDNS of the server is within yahoo.com”.  Can you tell me how to do that please? Kind regards,   VoIP | Broadband | Domain hosting | Web design & SEO emailitis.com   |  01722 770004   |   Cross Keys House, Queen Street, Salisbury, SP1 1EY emailitis.com is a trading name of Expat Email Ltd, Registered in England (No. 05140609)   VAT No. GB 843 7166 15  From: spamdyke-users-boun...@spamdyke.org [mailto:spamdyke-users-boun...@spamdyke.org] On Behalf Of Sam ClippingerSent: 16 September 2012 22:51To: spamdyke usersSubject: Re: [spamdyke-users] How best to whitelist rejected emails This is an RBL rejection, which means that the remote IP address has been blacklisted by a DNS RBL provider you're using.  (If you upgrade spamdyke to the latest version, the log message will include the name of the RBL that generated the match.)  I point this out because you may not want to whitelist this -- it may actually be spam. If you don't want to just whitelist the entire btinternet.com domain from any source, you could use a configuration directory to whitelist any sender within btinternet.com when the rDNS of the server is within yahoo.com.  That would help cut down on the false negatives.  You could further restrict the whitelist to only trigger when the recipient is also within a specific domain(s) on your server.-- Sam ClippingerOn Sep 16, 2012, at 4:00 PM, emailitis.com wrote:We are getting BT emails rejected like: Sep 12 20:56:28 plesk3 spamdyke[20050]: DENIED_RBL_MATCH from: external-per...@btinternet.com to: hosted-em...@hosted-domain.com origin_ip: 77.238.189.199 origin_rdns: nm2-vm0.bullet.mail.ird.yahoo.com auth: (unknown) encryption: (none) I could whitelist the sender (not recommended I know).  But is there a better way to ensure that all btinternet emails (now owned by yahoo) can be whitelisted? Also, if we were to whitelist a sender, is the email address only shown in the whitelist_senders file? Kind regards,  Christoph ___spamdyke-users mailing listspamdyke-users@spamdyke.orghttp://www.spamdyke.org/mailman/listinfo/spamdyke-users ___

Thank you Sam for your speedy response.  How can I tell if I have the latest
version?  Can you tell me what shell command to run?  And to update, is it
simply "yum upgrade spamdyke"?

 

I do not want to whitelist the whole btinternet.com domain as there will be
Spam.  I really like your idea to "use a configuration directory to
whitelist any sender within btinternet.com when the rDNS of the server is
within yahoo.com".  Can you tell me how to do that please?

 

Kind regards,

This is an RBL rejection, which means that the remote IP address has been
blacklisted by a DNS RBL provider you're using.  (If you upgrade spamdyke to
the latest version, the log message will include the name of the RBL that
generated the match.)  I point this out because you may not want to
whitelist this -- it may actually be spam.

 

If you don't want to just whitelist the entire btinternet.com domain from
any source, you could use a configuration directory to whitelist any sender
within btinternet.com when the rDNS of the server is within yahoo.com.  That
would help cut down on the false negatives.  You could further restrict the
whitelist to only trigger when the recipient is also within a specific
domain(s) on your server.
