Hi, I'm a novice on PI Notification and working on this these days


In my implementation, I was going to send notification email to my @realiv-tech.com, @gmail.com and @126.com emails


while following the instruction, I installed smtp service component into my machine on which Notification was installed. Configured realiv-tech.com domain and finished the configuration in PI Notification add-in in System Explorer.


While in the end, with the help of technical support, I could eventually send notification email to my realiv-tech.com email: kevin@realiv-tech.com


After I added 2 new remote domains: gmail.com and 126.com under default virtual server but I couldn't send email to my these 2 emails


Below is what is showned in IIS smtp configurator(sorry it's not convenient to put snapshots)


Domain Name                                      Type


realiv-tech.com                          Local(Default)


test.com                                   Local(Custom)


gmail.com                                 Remote


126.com                                    Remote




and I found whatever I changed to realiv-tech.com(change domain name, change smtp port etc), it always worked on sending notification email


but for gmail.com and 126.com, I cannot fix all the time, but got a error like:


From Primary SMTP server: 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. k23sm5035155waf.5


Could anyone give me a brief introduction on this problem? Thanks for any comment.
