Dynamic mailing lists
Some lists must be dynamically-created (for example: level1-lbl or for all members of a division) based on Orgcode or HRIS data. These change often and manual updates are not appropriate. Where possible, the IT Division can programmatically create and update these organization based lists for you using Sympa (lists.lbl.gov). Request help from the IT Help Desk (firstname.lastname@example.org).
