Recently I updated to SIMS 1.8b8 in order to be able to use multiple blacklist DNS servers to cut down on the spam. Modeling one poster's settings I'm using the following dns blacklist:
sbl.spamhaus.org spamsites.relays.osirusoft.com dialups.relays.osirusoft.com relays.visi.com (This is in addition to another 20 or so IP address ranges in the server's blacklist; these were from known spam relays or dialups used for relays from a couple of years back that were widely circulated on this list.) However, since using the 4 blacklist dns servers I've noticed a substantial pause on the server (the clock doesn't move) when there is incoming mail, lasting for about 20 seconds. Is this a normal byproduct of the dns lookups that are going on? This generally wouldn't be a big deal for the amount of mail this server processes, but since it does reside on our main web server (Webstar), it is impacting that. ############################################################# This message is sent to you because you are subscribed to the mailing list <[EMAIL PROTECTED]>.
