Mailer object error message "SMTP: invalid from address. SMTP error 530 5.7.0 Must issue a STARTTLS command first. d5sm35857280yhl.19".

I am trying to send an email from Lookout V6.6 using the Mailer object.  I have an email address setup through GMAIL and have verified it works.  Also, Lookout Mailer object is able to verify GMAIL server.  I get the following error message when trying to send the email: "SMTP: invalid from address. SMTP error 530 5.7.0 Must issue a STARTTLS command first. d5sm35857280yhl.19".  Anyone know what is causing this?

Lookout mailer object doesn't support TLS(Transport Layer Security), however the Gmail requires it. You need to choose another mail server. As far as I know, Gmail, Live and Yahoo requires the TLS.

Ryan,

Thanks for your response.  I ended up using another email account that does not require TLS.  Is there a reason Lookout does not support TLS?  Other SCADA applications do.  Any plans to add this support?

Another method is to use a SMTP relayer, we have deployed them in the past.
