E-mail configuration

Configuring e-mails in STEP 7
In the "E-mail configuration" entry, you configure the protocol to be used and the data for
access to the e-mail server in STEP 7.
In the message editor ("Messages" entry in STEP 7), you configure the individual e-mails,
see section Messages (Page 86).
E-mail configuration
With the default setting of the SMTP port 25, the CP transfers unencrypted e-mails.
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.
