Configuring Address Lookup

What are Directory Services for Email?

Most email software clients (for example, Thunderbird and Apple Mail) can be configured to look up email addresses as you type in a person's name. This service looks up a name in the College's email address directory if it doesn't find the name in your personal directory. Likewise, you can type in a faculty/staff/student email ID and see the name of the person associated with that ID.

This works from on-campus, or from off-campus if you are connected through theVPN (virtual private network).

Setting Up Your Email Client

You may configure your own email client using the brief instructions below, or call the Help Desk for assistance. These instructions may not match your environment exactly, as there are small changes across versions.

Using the Service to Address a Message

Once you have configured Thunderbird or Apple Mail, you may simply start typing a name in the To:, Cc: or Bcc: fields of a new email message. The names will auto-complete and the list will narrow as more characters are provided, giving the names from your personal address book first.

To search the directory in Thunderbird, click the Contacts button in your message, switch the Address Book to Swarthmore Directory and then search on any part of the name or email address. (Outlook works a bit differently: instructions.)

For example, if you want to write to a person named Ben Jones, you may start typing "ben" in the To: field and everyone with "ben" in his/her name will show in a drop-down box. If you type "ben jones", "Benjamin Jones " will list and you can select his name and continue. For students, the class year appears after their names like this: "Benjamin Jones '11 ".
