Defining Filter Strings
Messages are filtered based on the information contained in their To, From and Subject
header fields. The information that defines what your SPT 1700 terminal is looki ng for is
called a filter string. You create a filter string by listing the words you want your SPT 1700
terminal to find and separating them with either a comma or a space. Each word in the filter
string is joined by an implicit OR; do not enter connecting words s uch as AND or OR.
To create a more complex filter, you can define filter strings for the To, From and Subject
fields simultaneously. Your SPT 1700 terminal joins the filter strings for these fields using
an implicit AND, so do not add connecting words. Your SPT 1700 terminal does that for you.
For example, suppose you want to receive only messages from John Smith
(jsmith@aol.com) or Jack Jones (jjones@aol.com) concerning the Ap ollo Project. You
would create the following filter strings:
To field filter string: jsmith@aol.com, jjones@aol.com
Subject field filter string: Apollo Project
Your SPT 1700 terminal interprets this as, “Accept messages about the Apollo Project fr om
John Smith or Jack Jones. Do not accept messages from other people. Do not accept
messages from John or Jack about any other subject.”
When you define a string, note that your SPT 1700 terminal searches for any instanc e of
that collection of characters. For example, if you create a filter that retrieves only messages
containing the string “info,” your SPT 1700 terminal considers “info,” “rainforest” and
“kinfolk” appropriate matches.

the defined criteria and to ignore all other messages during
synchronization. This filter may block mor e mail during sy nchronizati on
because it downloads only one subset of mail.
