Abstract
Presence subscriptions for messaging services are managed by automatically subscribing contacts to a user's contact lists based one or more rules, subscription states and contact types. In some embodiments, presence subscriptions are managed by: identifying a set of contacts with respect to an identified user; applying subscription rules to the contacts; selecting a subset of contacts based on one or more subscription rules; and automatically establishing presence subscriptions for the subset of contacts.
