More info: Sure enough, there was a later version on the web site, taking me from v3.2 to 3.2.0.92-3. :^>
So I installed the package, and tried the smtp_remote_allow in the config file, as mentioned for smail 3.2. No such luck, it doesn't know that configuration option. *IF* that configuration option is possible under the smail compiled under Libc6, then when the entire box is upgraded maybe it will work. But for now, I seem stuck unless someone has some magic tcp wrappers or smail configuration lines that will do what smtp_remote_allow (or "-smtp_remote_allow") is supposed to do.

Here's a good link: http://maps.vix.com/tsi/ar-fix.html It says: Smail Version 3 Status: Freely Available Systems: Unix Info: http://www.sbay.org/smail-faq.html smail version 3.2 has support to block unauthorized relay. This is enabled by defining the smtp_remote_allow parameter in your config file. Set it to the list of local IP address ranges from which unrestricted relay is allowed. All other hosts will be refused. Smail version 3.1 is vulnerable to relay. It also has some well-known security problems. Please upgrade to either version 3.2 or exim.
