I installed a local caching name-server and that seemed to help my
mail-server quite a bit. I am checking at the spamassasin level, i
think its the most accurate but probably the most intensive.<br>
<br>
It seems to be common to add spamhaus at the MTA level as its
considered extremely accurate so unlikely to cause many (if any at
all!) false positives!<br><br><div><span class="gmail_quote">On 26/10/06, <b class="gmail_sendername">Scott Silva</b> <<a href="mailto:ssilva@sgvwater.com">ssilva@sgvwater.com</a>> wrote:</span><blockquote class="gmail_quote" style="border-left: 1px solid rgb(204, 204, 204); margin: 0pt 0pt 0pt 0.8ex; padding-left: 1ex;">

> since you are using sbl+xbl, you can drop spamhaus-xbl, <a href="http://spamhaus.org">spamhaus.org</a>, and CBL<br>> as they are all done in the sbl+xbl lookup. That drops 3 extra lookups.<br>> You could look in your logs and see if any of the lookups have a very low
<br>> hitrate, or are redundant with the sbl-xbl list, which hits a lot of stuff.<br>> You could try spamassassin, as it will do multiple lookups at once, and<br>> Mailscanners spamassassin cache can help lighten the load.
<br>> Have you done all the optimizing ideas in the wiki?<br>> Are you running a caching nameserver on the box?<br>><br>> Can you put any of these in the MTA? That will drop mail before your machine<br>> even has to touch it.
<br>><br>><br>SBL+XBL also includes NJABL, so there drops another lookup.<br><br><br>--<br><br>MailScanner is like deodorant...<br>You hope everybody uses it, and<br>you notice quickly if they don't!!!!<br><br>--<br>
