Expert - E-mail

The HS/FS uses sending via e-mail for the following data:
- Alarm messages
- Data archive
- Message archive
- Camera images
- KNX monitor
- Status pages
- System lists

Note

All settings (e.g. ports used, names of the POP3 and SMTP server) are usually specified on the provider's Internet page.

1.Definitions

POP / POP3
Post Office Protocol
A protocol via which e-mails can be picked up from an e-mail server.
POP3 = Version 3 of this protocol.
Requires authentication.
SMTP
Simple Mail Transfer Protocol
A protocol via which e-mails can be sent to an e-mail server which forwards them to the actual recipients. Does not require authentication.
TLS
Transport Layer Security
SSL
Secure Sockets Layer
The previous name of TLS
STARTTLS
Compound of "Start" and "TLS".
POP before SMTP
Because some older SMTP servers do not have their own authentication methods, a POP3 connection (which requires authentication) is established first when using them. An SMTP connection is not established until this occurs.

Use e-mail sending

Yes: E-mail sending is enabled for the project.

Note

If e-mail sending is used in the project, it can no longer be deactivated here!

Connection security

The following connection types are supported by HS/FS:

Unencrypted
The connection is not encrypted.
Unencrypted with POP before SMTP
The connection is not encrypted. User name and password must be specified.
Note
No longer supported by many providers.
STARTTLS
STARTTLS is a process for initiating (starting) the encryption of communication using TLS.
This process enables encrypted communication. When the HS/FS connects to the e-mail server, it indicates whether encrypted communication is possible. The HS/FS detects this and depending on the answer from the e-mail server, the following communication is performed either encrypted or unencrypted.
SMTP over SSL/TLS
Communication between HS/FS and the e-mail server is encrypted.
This is the most secure method of communication.

Note

So that each method can be used, it must also be supported by the selected provider.

SMTP server

Sending via e-mail occurs via this server.

2.IP port

The HS/FS communicates with the e-mail server via this port.
See also the list at the end of this document.

Own e-mail address

A valid e-mail address for the sender is entered here.

Note

Depending on the configuration of the e-mail server, it is possible that the "Own e-mail address" must belong to the e-mail account with the following login data (user name/password)!

User name

The HS/FS logs in on the e-mail server with this name.

Password

The HS/FS logs in to the e-mail server with this password.

POP3 server

Address of the server for retrieving the e-mails; this address is only necessary for the POP before SMTP process. If in doubt, contact the network administrator or e-mail provider.

Important

The HS/FS does not receive or retrieve any e-mails; this setting is only to log on initially in combination with POP before SMTP!!
POP3 = Post Office Protocol - Version 3

3.Calling up the debug page when starting the HS/FS

Important

When automatically sending debug pages by e-mail when starting the HS/FS, it must be ensured that the call doesn't occur until the internal system communication object "System (after start always 1)" is set to 1 because the data on the debug page could otherwise be incomplete or faulty.
