Figure 43: Sending e-mail from client to DECT Messenger
In DECT Messenger, the eSMTP_Server works in cooperation with the Microsoft Internet
Information Services (IIS). It is possible that other e-mail servers can be used instead of IIS,
but they are not supported.
• eSMTP (client)
eSMTP behaves like an e-mail client program that sends e-mail messages to an e-mail
server. The format is the standard SMTP (Simple Mail Transfer Protocol) defined in the RFC
821 specification.
If a Lotus Notes Domino server is installed on the system, there must also be a Lotus Notes
SMTP server that is capable of receiving SMTP messages from DECT Messenger. You
cannot send an e-mail message from DECT Messenger directly to a Domino server.

How eSMTP Works
The eSMTP_Server handles incoming e-mail messages, working in cooperation with IIS. In
Figure 44: e-mail handling in DECT Messenger on page 132 the structure of the e-mail path
is depicted.
