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 88).
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.
If you want to use the secure transfer of e-mails, the CP must have the current time of day.
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.
To import the certificate, follow these steps:
1. Save the certificate from your e-mail service provider in the file system of the engineering
station.
2. In STEP 7, select the entry "Global security settings > Certificate manager" in the "Project
tree".
3. Change to the "Trusted certificates and root certification authorities" tab.
4. Select any row in the table "Trusted certificates and root certification authorities".
5. Select the "Import" entry in the shortcut menu.
6. In the dialog that follows, select the required certificate.
