			<content:encoded><![CDATA[<p>Found a nice little kicker today. At some point in the past few months, <a href="http://www.columbia.edu/cuit">CUIT</a> reconfigured their mail servers to only accept mail with a proper &#8220;MAIL-FROM&#8221; header response. Also, at some point (probably last year when we upgraded the box to 10.5 Leopard), Apple decided that it would be wise to switch the &#8220;www&#8221; user to have the primary name &#8220;_www&#8221; instead. Makes it less ambiguous if you had an OD user with the name &#8220;www&#8221;, but since all of my usernames are of the format of two to three letters and then at least one digit, it&#8217;s not a problem.</p>
<p>The result?<br />
<code>Apr  1 00:50:39 projects postfix/smtp[393]: 21386ACF69A: to=&lt;*****@columbia.edu&gt;, relay=external-smtp-multi-vif.cc.columbia.edu[128.59.48.6]:25, delay=0.98, delays=0.68/0.24/0.03/0.03, dsn=5.7.1, status=bounc<br />
ed (host external-smtp-multi-vif.cc.columbia.edu[128.59.48.6] said: 554 5.7.1 Bad sender address (in reply to end of DATA command))</code></p>
<p>Basically, no matter what I told PHP to use for sendmail_from, at some point, postfix was just setting it to _www@&lt;my domain name&gt;. A quick and easy solution:</p>
<ul>
<li>Open Workgroup Manager.</li>
<li>Authenticate to the local directory (pick &#8220;Local&#8221; from the dropdown)</li>
<li>Go to Preferences, and select &#8220;Show &#8216;All Records&#8217; tab and inspector&#8221; if not already checked.</li>
<li>Click on the &#8220;all records&#8221; tab (next to computer lists, looks like bulls-eye)</li>
<li>Select &#8220;Users&#8221; from the dropdown, then _www from the user list</li>
<li>Delete the &#8220;RecordName&#8221; value _www, leaving just the &#8220;www&#8221; value (if _www is the only one, then just rename _www to www).</li>
<li>That&#8217;s all!</li>
</ul>
<p>Your mileage may vary, etc. but since I couldn&#8217;t find anything on google regarding this error, thought it would be nice to share.</p>
