MAIL_ADDR_PARAM parameter
At the MAIL_ADDR_PARAM parameter, you define the connection for sending the e-mail in
the structure Tmail_v4 or Tmail_FQDN, and save the e-mail server address and login details.
The structure you use at the MAIL_ADDR_PARAM parameter depends on the format in
which the e-mail server is to be addressed:
● Tmail_v4: Addressing by IP address (IPv4).
● Tmail_FQDN: Addressing by fully qualified domain name (FQDN).
Which structure you can use depends on the interface addressed at the InterfaceId
parameter. If you want to use the "TMAIL_C" instruction with the internal interface, the
structure Tmail_v4 must be used at the MAIL_ADDR_PARAM parameter.
