Configuration of the Sms4Domino mail interface document
The mail interface document must have enabled the receipts of status delivery reports
How is the delivery report matched to the outbound recipient
The end user sends a SMS message to the number 12345678. The GSM network assigns a
sequence number to this Sms message. A few minutes later the delivery report is received by
Sms4Domino. This delivery report contains the sequence number and the phone number
where the Sms was delivered.
The sequence number is only 8 bits wide. So there are only 256 distinct sequence numbers.
In heavily used environments Sms4Domino may find more than one outbound Sms with the
same sequence number. A better match is achieved by combining the sequence number with
the recipient's phone number. However this match may fail because the phone nunber in the
delivery report could be different from the phone number in the outbound Sms. E.g. the
delivery report may prefix the number with the country code. Sms4Domino requires an exact
match between the outbound phone number and the one specified in the delivery report.
In order to be able to match the delivery report with the outbound Sms, Sms4Domino must
keep the outbound Sms long enough in the Domino configuration database. This is defined
by the setting Outbound SMS retention time on the mail interface document.
