C.5.12.1 Additional sms_option File Settings

The additional settings for the sms_option file are:

! So that we don’t add text to the body of the SMS message
FROM_FORMAT=
SUBJECT_FORMAT=
CONTENT_PREFIX=

Without these settings, an email containing:

user@domain.com (Sample subject) Sample text

would get converted into the SMS message:

From:user@domain.com Subject:Sample Subject Msg:Sample text

That, in turn, would not be in the format expected by the mobile-to-email code, which wants to see:

user@domain.com (Sample subject) Sample text

Hence the need (for loopback testing) to specify empty strings for the FROM_FORMAT, SUBJECT_FORMAT, and CONTENT_PREFIX options.

Performing the Loopback Test

Send test email messages addressed to 000@sms.domain.com, such as:

user@domain.com (Test message) This is a test message which should loop back

The result is that this email message should be routed back to the email recipient user@domain.com.Be sure to have added sms.domain.com to your DNS or host tables for the test.
