Correct. The "Spam Checks" parameter covers *all* the spam
checking.<br><br>

if "Spam Checks = yes" and "Use SpamAssassin = yes"
then SpamAssassin is run, but MailScanner also does internal spam
checking,</font></blockquote><br>
correct.<br><br>
<blockquote type=cite class=cite cite><font face="arial" size=2> and
cannot be disabled simply by setting "Spam List = " and
"Spam Domain List = " or by commenting both
out.</font></blockquote><br>
Don't comment them out, set them to nothing and that should disable the
MailScanner RBL checks.<br><br>
<blockquote type=cite class=cite cite><font face="arial" size=2><b>2.</b></font><br>
<font face="arial" size=2>Maybe this is a bug, but I'm not sure at this

<font face="arial" size=2> "Spam Checks =
yes",</font><br>
<font face="arial" size=2> "Spam List = ",
</font><br>
<font face="arial" size=2> "Spam Domain List =
",</font><br>
<font face="arial" size=2> "Use SpamAssassin =
yes" </font><br>
<br>
<font face="arial" size=2>then the following appears in the log
file</font><br>
<br>
<font face="arial" size=2>Feb 24 15:34:25 mailhost MailScanner[5658]:
SpamAssassin timed out and was killed, consecutive failure 1 of 20 <br>
Feb 24 15:34:36 mailhost MailScanner[5658]: RBL Check timed out and
was killed, consecutive failure 1 of 7 <br>
Feb 24 15:34:52 mailhost MailScanner[5658]: SpamAssassin timed out and

<br>
<font face="arial" size=2>It would apear that if you change to "Use
SpamAssassin = no" , then the RBL Check timed out messages DO NOT
appear in the syslog output. So maybe this is a bug or some kind of
dependency on spam assassin that causes this??? But if SA times out this
should not cause MailScanners internal RBL to timeout as well.
</font></blockquote><br>
Agreed, unfortunately I have had difficulty reproducing this fault
reliably, which makes it hard to track down. If your SpamAssassin calls
are always timing out, then there is definitely something wrong
anyway.<br><br>
<blockquote type=cite class=cite cite><font face="arial" size=2>This
dependency on SA is why I suspect you cannot disable internal spam
checking with MailScanner even if you set the Spam List check to null. I
would much rather use SpamAssassin and not use MailScanner for spam
checking at all. </font></blockquote><br>
Setting the "Spam List =" and "Spam Domain List ="
should achieve that.<br><br>
<blockquote type=cite class=cite cite><font face="arial" size=2><b>Using
the buggy SA 2.50, no emails were getting through the system at all, and
the CPU utilization would jump to 100%. Since then I have uninstalled SA
