 <p>I followed the <a href="http://support.sas.com/kb/53/105.html" rel="nofollow">support link</a> you provided, which states the following:</p> <blockquote> <p>With SAS® 9.3, the following message occurs in your SAS log when you use aliases for the value of SMTP MAIL FROM:email address and your SMTP server does not support aliases.</p> </blockquote> <p>The code above does not appear to contain a value for the FROM email address. Try configuring the following <a href="http://support.sas.com/documentation/cdl/en/lrdict/64316/HTML/default/viewer.htm#a002135033.htm" rel="nofollow">option</a> at the start of your process:</p> <pre><code>options emailid="bobby1232@email.com"; /* adjust as appropriate */ </code></pre> <p>Alternatively, try adding it to your filename as follows:</p> <pre><code>filename mymail email to=("&amp;to.@email.com") from="bobby123@email.com" TYPE = "TEXT/PLAIN" SUBJECT = "Report Status"; </code></pre>
