Figure 44: e-mail handling in DECT Messenger
After an e-mail is sent from the e-mail client to DECT Messenger, the e-mail generally goes
through an e-mail provider (through a server). In this e-mail Server, relaying must be switched
on, otherwise the e-mail is not transferred to DECT Messenger. Also, the e-mail Server must
know to which PC the e-mail message is to be sent. Therefore, a DNS Server must be assigned
in the e-mail Server, and within that DNS server, an MX record must define the relation to the
DNS name of the DECT Messenger PC.
After an e-mail is sent to DECT Messenger, the message arrives at the IIS SMTP server. The
IIS SMTP Server stores the mail message as a file in a specified directory on the hard disk.
This directory is the interface between IIS and the eSMTP_Server software. The
eSMTP_Server checks the contents of this directory every 10 seconds. If there is a mail
message, eSMTP_Server loads and analyses it as follows:
• The e-mail address on DECT Messenger (for example, [e-mail]) is the
message destination (a Group in the DECT Messenger configuration).
• The subject of the e-mail message is the message that is sent.
• The originator's e-mail address is the address to which the confirmation message is sent
using the eSMTP client.
After processing the e-mail message, the eSMTP_Server puts the message in the directory
C:\inetpub\mailroot\drop\processed. If the message cannot be properly processed,
eSMTP_Server does not put the message in the processed directory, but in the directory C:
\inetpub\mailroot\drop\error.
Note:
You do not need to create users in the IIS. IIS is used for incoming SMTP only. On incoming
e-mail, no authentication check is done. A message to any user (the address part preceding
