mail_restrict_follower_selection

Purpose

Restricts follower selection and auto-follow behavior to partners that satisfy configurable domain rules.

Features

configuration: System parameters define default and per-model domains for allowed follower partners, with a setup action to guide configuration.
mail.wizard.invite: Applies the configured domain to the invite wizard partner picker so only allowed contacts can be selected as followers.
mail.followers: Prevents adding followers whose partners fall outside the configured domain, with context flags to bypass the restriction when needed.
mail.thread: Excludes suggested recipients from message suggestions when their partner records do not satisfy the follower restriction domain.
