Perhaps one of the most complete answers is contained in this posting at <A HREF="http://www.logsat.com/spamfilter/forums/showmessage.asp?messageID=2618" CLASS="ASPForums" TITLE="WARNING: URL created by poster. "><A HREF="http://www.logsat.com/spamfilter/forums/showmessage.asp?messageID=2618" CLASS="ASPForums" TITLE="WARNING: URL created by poster. "><U><FONT color=#4682b4 size=2><A HREF="http://www.logsat.com/spamfilter/forums/showmessage.asp?messageID=2618" CLASS="ASPForums" TITLE="WARNING: URL created by poster. ">http://www.logsat.com/spamfilter/forums/showmessage.asp?messageID=2618</A></FONT></U></A></A>. Hope this helps.</P><P>On a side note, if you configured a default destination SMTP server and port in the main settings tab, there is no need to specify the following line in your Local Domains whitelist:</P><P>hillersystemsinc.com:mail.hillersystemsinc. com:25</P><P><BR>Roberto F.<BR>LogSat Software<BR></P>]]>
