1. Start Mail.

  • If this is the first time you are using Mail, when Mail opens, click Continue.
  • Or, if Mail is already configured and you are just adding this account, go to File-Add Account.

2. Indicate that your Account Type is IMAP and fill in your name and email address. NOTE: If the setup tries to search for mail servers instead of letting you designate the Account Type, click on Cancel and then click Continue.

Instead of the default “IMAP Account” Account Description, you can use something like “BU mail” if you want to.

3. Then click Continue.

4. The incoming mail server is acs-imap.bu.edu. Your User Name is your BU login name (the portion of your BU email address that comes before @bu.edu. For example, if your BU email address is jschmoe@bu.edu, your login name is jschmoe). The Password is your Kerberos password.

5. Click Continue.

6. The outgoing mail server is acs-smtp.bu.edu.

Our mail server supports SSL user authentication, so check Use Authentication to send mail easily from both on and off campus.

7. Click Continue. Make sure there is a check next to Use Secure Sockets Layer (SSL). Set Authentication to Password.smtp_auth_type

8. Click Continue and Done (unless you are running Mail for the first time and need to Import messages from another email program. If so, you should follow the instructions on the screen).

10. Look through Mail->Preferences to make sure everything is configured in the way you want. In the Advanced window, indicate that you want to Use SSL (port 993) with Password authentication. You might also consider setting up online address lookup (LDAP) as explained below. After that, you’re all set! Close your Preferences and you can start using Mail.

11. If you have any trouble sending mail the first time after you set your account preferences, quit and restart the Mail program and then try again.

About the Mail directory

If, after configuring your mail program and connecting to the server, you do not see your known/existing mail folders, or you see a lot of extra files that you didn’t expect to see, set the Root folder path (a.k.a. the IMAP Path Prefix) as Mail. This requirement is rare, but could be an issue for some ACS accounts created prior to February 19, 2008. To make that change, go to Mail->Preferences->Accounts->Advanced and put Mail/ as the IMAP Path Prefix so that any other folders you have on ACS will display correctly. After making that change, you may then be prompted to refresh your folder list, which you should do.

Optional: the BU LDAP server

1. Once that’s all working properly, you may want to configure the BU LDAP server. This lets the Mail program look up BU email addresses in the BU online directory. Go to Mail-Preferences-Composing and click on the Configure LDAP button.

2. Click the + button and use a Name like BU LDAP SERVER. The Server is ldap.bu.edu. The Search base is o=Boston University, c=US (where “o” is the small letter o, not the numeral zero). Then click Save and Done.
