Posted on by DHAN RAJ 2

Hi All,

I am getting following error while sending email from NAV5 (on SQL Server) using SMTP. I am using GMAIL for sending emails and it uses port 587. For providing Port No. as parameter, I have updated the objects as described in Hot Fix (knowledge artcile KB981354 https://mbs2.microsoft.com/Knowledgebas ... wsignin1.0):

The SMTP mail system returned the following error: The SMTP server requires a secure connection or the client was not authenticated. The server response was: 5.7.0 Must issue a STARTTLS command first. va6sm42890097igc.6

What should be done for resolving this issue?

Thanks

Please check if "SMTP Mail Setup" table has "Secure Connection" checked.

Moreover, does your SMTP server support SSL connections?
