A small note:
MacOS X 10.3 use Postfix as mail program. There is a problem with AOLServer 3.3 and Postfix but it could easily be fixed by modifying the file "/usr/local/aolserver/modules/tcl/sendmail.tcl" Look for "_ns_smtp_send $wfp "HELO AOLserver [ns_info hostname]" $timeout" and remove "AOLserver".
This bug is fixed in AOLserver 4.
