&lt;br /&gt;
conf.mailhandler.ntf_sndr_addr=admin@XXXX.com&lt;br /&gt;
conf.mailhandler.email.domain=XXXX.com&lt;br /&gt;
conf.mailhandler.mail.smtp.host=smtpout.XXXX ----- it worked on Secure url without defining the secure SMTP port &lt;br /&gt;
conf.mailhandler.mail.smtp.auth=true&lt;br /&gt;
conf.mailhandler.mail.user=admin@XXXX.com&lt;br /&gt;
conf.mailhandler.mail.transport.protocol=smtp&lt;br /&gt;
conf.mailhandler.mail.smtp.starttls.enable=false&lt;br /&gt;
conf.mailhandler.mail.smtp.starttls.required=false&lt;br /&gt;
&lt;br /&gt;
If i use the secure smtp url with port defined i get error message &amp;quot;Could not connect to SMTP host:&amp;quot;,  if i use non secure SMTP url with port other than 25 i get &amp;quot;Sender address rejected: Access denied&amp;quot; it looks like it only works on default SMTP at least for our email provider&lt;div style="clear:both;"&gt;&lt;/div&gt;</description></item><item><title>RE: Could not send emails</title><link>https://community.appian.com/thread/54335?ContentTypeID=1</link><pubDate>Mon, 23 Apr 2018 07:25:35 GMT</pubDate><guid isPermaLink="false">d3a83456-d57b-489c-a84c-4e8267bb592a:1c878618-89c7-442c-9c5c-c79fb7764694</guid><dc:creator>Benhail</dc:creator><description>&lt;p&gt;In custom.properties files, make sure the following details are entered.
