Bonjour,
We'd like to use the SMTP server of our customer for sending emails. This means that the customer is also obliged to take care that his provider is not listed on any blacklist and therefore his end customers do not receive their confirmation emails.
We configured the followeing settings:
SmtpServerAddress smtp.office365.com
SmtpServerPassword *******
SmtpServerPort 587
SmtpServerUser *******
We receive the following error which shows that the encryption wasn't started correctly. We'd suggest not to use STARTTLS but SSL/TLS because connection establishment using STARTTLS is not encrypted and it's recommended to use SSL/TLS instead.
Sending email
Error in processing. The server response was: 5.7.3 STARTTLS is required to send mail [xxxxxxxxxxx.prod.exchangelabs.com]
I've set up a testMail app in a sandbox workspace for quick and easy testing without using the productive environment of the customer.
Thanks for fixing this issue shortly.
Patrique
