I'm running exim in daemon mode BTW. I followed all the suggestions relevant to my setup and my server is performing better now. And most importantly, I think I may have found the reason for my delays. I wasn't paying attention to the log entry regarding the speed before and when I finally checked, I discovered my server takes about 800 seconds to process 150 messages even when I'm already running a local dns caching service. My solution now is to run rbldns and cache a few blacklists locally. And since SpamAssassin uses surbl, I will need to cache it locally as well. Do you guys have any suggestions on which 4 (I'm planning on only 4) RBLs to cache? And also which RBLs allow their data to be cached somewhere else. I'm thinking of the following: 1. DSBL (already in effect on my server) 2. spamcop.net 3. spamhaus.org 4. sorbs.net
These 4 will be in my MailScanner.conf file. No need to include surbl since SpamAssassin already uses it by default. Do you know if spamcop, sorbs , and spamhaus allow local caching for _free_? If not, can you suggest which RBLs allow local caching for free. Thanks!!! -- Cheers, Edward C.
