<p>... And if one don't like/can use the commercial license of milter-ahead, there is smf-sav (another milter)which one can configure to only do recipient verification. Have never seen a performance comparison between them, but I imagine they are pretty similar... And smf-sav had a pure OSS license, last I looked (admittedly a while back:-).</p>

milter-ahead is going to be a ton more efficient than any perl based script. milter-ahead is written in C, supports caching and numerous indexed or flat text file databases for the local cache. <br><br><br>Chris<br><br><div class="gmail_extra">

<p><span lang="EN-US">IIRC this was never detailed in the main site, but rather in the wiki ()...
</span>Somewhere under the docs for the respective MTA...</p><div><div><br>
The script you refer to was most likely for Postfix, but ISTR someone adapting that for Sendmail use, but the bottom line is that nowadays... Neither MTA needs that hack. In Sendmail, use a milter (there are more than one that will do this, at least some that
are FOSS;-), in Postfix use the docs for recipient verification as found in the postconf man page/ob the
<a href="http://postfix.org" target="_blank">postfix.org</a> site (it might still be in the sender address verification doc there... don't do that, just the recipient bit)... Or, as said, look in the wiki (might be slightly dated info there;-).<u></u><u></u></div>
</div><p></p><div><div>
<p>Having said all that, I personally still use a homegrown script around the open-ldap tools and postmap, more for historical reasons/lazyness tgan anything else. The reason for it all dates back to the time when I was protecting an Exchange 5.5 which was
managed by a contrary fellow who wouldn't even try make it correctly reject unknown recipients. Now... I'm in charge of the Exchange bit too, and the defaults for that MTA has changed, so it will reject as expected (that too changed quite a few versions back...
In Exchange 2000, IIRC:-).<u></u><u></u></p>

<p class="MsoNormal"><span lang="EN-US">Hi, for a couple of years ago there was a guide on
