Security Functions - Siemens CP 1243-8 IRC Operating Instructions Manual

If your e-mail service provider only supports encrypted transfer, use one of the following
options:
● Port no. 587
By using STARTTLS, the CP 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 CP sends encrypted e-mails to the SMTP server of your
e-mail service provider.
Ask your e.mail service provider which option is supported.

station.
