Answer 1

i tested smtp connector and it is working fine in mule flow , below is my code.
but here i used SMTPS
<http:listener-config name="HTTP_Listener_Configuration"
host="0.0.0.0" port="8081" doc:name="HTTP Listener Configuration" />
<flow name="yahooemailFlow">
<http:listener config-ref="HTTP_Listener_Configuration"
path="/" doc:name="HTTP" />
<set-payload value="#['Test Message ']" doc:name="Set Payload" />
<smtps:outbound-endpoint host="${smtp_host_ip}"
responseTimeout="10000" doc:name="SMTP" from="fromemail#yahoo.com"
mimeType="text/html" password="password" subject="subject"
to="toemail#yahoo.com" user="fromemail%40yahoo.com" />
<logger message="Mail Sent #[payload]" level="INFO" doc:name="Logger" />
</flow>
