3Com TRGpro manual Defining filter strings

Retrieve Tells your handheld computer to include Only Msgs only the e-mail items that meet the criteria Containing you define and to ignore all other e-mail

items during synchronization. This filter has the potential to block more e-mail during synchronization because it downloads only one subset of e-mail.

Defining filter strings

E-mail items are filtered based on the information contained in their To:, From:, and Subj: fields. The information that defines what your handheld computer is looking for is called a filter string. You create a filter string by listing the words you want your handheld computer to find and separating them with either a comma or a space. Each word in the filter string is joined by an implicit OR, so you do not need to enter logical connectors like AND or OR.

To create a more complex filter, you can define filter strings for the To:, From:, and Subj: fields simultaneously. Your handheld computer joins the filter strings for these fields using an implicit AND; once again, you do not need to add the logical connector. Your handheld computer does that for you.

For example, suppose you want to receive only e-mail items from John Smith (jsmith@aol.com) or Jack Jones (jjones@aol.com) concerning the Apollo Project. You would create the following filter strings:

In the To: field: jsmith@aol.com, jjones@aol.com

In the Subj: field: Apollo Project

Your handheld computer interprets this as, “Accept e-mail items about the Apollo Project from John Smith or Jack Jones. Do not accept e-mail items from other people. Do not accept e-mail items from John or Jack about any other subject.”

When you define a string, note that your handheld computer searches for any instance of that sequence of characters. For example, if you create a filter that retrieves only e-mail items containing the string “info,” your handheld computer considers “info,” “rainforest” and “kinfolk” appropriate matches.
