Subscriber Numbers - Siemens SIMATIC TeleControl DNP3 Configuration Manual

If your e-mail service provider only supports encrypted transfer, use one of the following
options:
● Port no. 587
By using STARTTLS, the module sends encrypted e-mails to the SMTP server of your e-
mail service provider.
Recommendation: If your e-mail provider offers both options (STARTTLS / SSL/TLS), you
should use STARTTLS with port 587.
● Port no. 465
By using SSL/TLS (SMTPS), the module sends encrypted e-mails to the SMTP server of
your e-mail service provider.
Ask your e.mail service provider which option is supported.
Importing the certificate with encrypted transfer
To be able to use encrypted transfer, you need to load the certificate of your e-mail account
in the certificate manager of STEP 7. You obtain the certificate from your e-mail service
provider.
Use the certificate by taking the following steps:
1. Save the certificate of your e-mail service provider in the file system of the engineering
station.
2. Import the certificate into your STEP 7 project with "Global security settings > Certificate
manager".
3. Use the imported certificate with every module that uses encrypted e-mails via the
"Certificate manager" table in the local "Security" parameter group.
For the procedure, refer to the section Certificate manager (Page 81).
