Attention Non-IMAP lbl.gov Email Users: Off-Site Authentication Procedure to Be Reinstated Beginning Saturday, Dec. 1

If you are NOT a user of the Lab's centralized IMAP4 email system and you use the Lab's central outgoing e-mail server to send email while offsite, you will again have to log in to the server and authenticate your identity once a week, beginning Dec. 1. This authentication requirement had been temporarily turned off while IMAP email accounts were being moved from one to several servers. This change affects only those employees who do not use the IMAP email and who use the Lab's email servers to send mail from offsite. Previously, users had to authenticate themselves daily, but the new procedure will only require once-a-week authentication.

To authenticate your identity, you will need to successfully enter your LDAP username and password at http://www.lbl.gov/smtp2/. This will provide outgoing e-mail service from offsite until the next Sunday, when you will need to renew your authentication. If you do not have an LDAP username and password, or need further assistance, contact the computer support Help Desk at X4357.
