<p class=MsoNormal><span lang=EN-US>Obtuse-smtpd is very easy to configure and
very effective. It takes control of all smtp activities over Port <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>25 and, after filtering and checking, passes
the safe mails to sendmail for final delivery. Obtuse can, also,<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>check for addressability, through DNS, of
the mail sender and other useful features.<o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US><o:p> </o:p></span></p>
<p class=MsoNormal><span lang=EN-US>Unfortunately, obtuse-smtpd is so old that
it works only (don’t be surprised) with old sendmail versions. <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>So, I always have to uninstall the in-OS
shipped modern sendmail version and replace it with the proper <o:p></o:p></span></p>
<p class=MsoNormal><span lang=EN-US>old version.<o:p></o:p></span></p>
