"javax.mail.MessagingException: 530 5.7.0 Must issue a STARTTLS command first."
Authentication has been enabled in the system.properties file as per Mail Service in a Niagara R2 UNC station configured correctly but e-mails not being sent to the SMTP....
Product Line
TAC IA Series
Environment
I/A Series R2
Cause
As with most public SMTP servers, like Gmail, the outgoing mail SMTP server requires TLS (Transport Layer Security) or SSL (Secure Sockets Layer) which I/A Series R2 does not support.
Resolution
Use an SMTP server that does not require TLS or SSL.
