Abstract: Embodiments are directed towards identifying trusted senders and their trusted sender accounts within a household network for use in at least managing spam activities. Primary trusted sender accounts are determined based on a traceable relationship between a network account and a known trusted source, such as a communication of qualified electronic statements. Coverage of trusted senders may be expanded by including other network accounts that might not receive qualified electronic statements but are detected as being owned by a primary trusted sender and/or their household members. The other household members being definable as secondary trusted senders with secondary trusted sender accounts. Various anti-spam filters and/or other activities may be modified based on the determined trusted sender status of a network account, including, minimizing an amount of spam analysis performed for a message, training of spam filters, or the like.
