Hi,
I got this sorted out for a @hotpop.com address (which has a free smtp
service), with the following configuration.
<transportSender name="mailto"
class="org.apache.synapse.transport.mail.MailTransportSender">
<parameter name="mail.smtp.host">smtp.hotpop.com</parameter>
<parameter name="mail.smtp.port">25</parameter>
<parameter name="mail.smtp.starttls.enable">false</parameter>
<parameter name="mail.smtp.auth">false</parameter>
<parameter name="mail.smtp.user">[email protected]</parameter>
<parameter name="mail.smtp.password">password</parameter>
<parameter name="mail.smtp.from">[email protected]</parameter>
</transportSender>
It took sometime for me to learn (thanks to Ruwan for the hint) that
<parameter name="mail.smtp.auth">true</parameter> does not quite mean the
same as ticking that your "server requires authentication" as in an E-mail
client. I'm yet to try this out with a @gmail smtp address (which is a bit
complicated as they use SSL. The actual exception was generated when the
transport sender was used to send e-mail through a @gmail address.
However, once I get some free time, perhaps next week, I'm looking forward
to add a small explanation to the Samples Guide in Synapse on what these
parameters actually mean and with a few sample configurations so that others
wouldn't run into the same problems I had. As of now, I only had one single
sample configuration which does not quite work.
Regards,
Senaka
