Exim has some user defined to run under it, but that user is used only for daemon (accepting TCP connections & queue runner). But when exim delivers message or is invoked from command line, it runs as particular user, either as target or calling user. In other words, if someone sends message to local user and local delivery happens, exim runs delivery proces as that users. If that message is for root, it will not run delivery with root privileges. When someone sends message via command line, exim runs as that user, but when root sends message, exim will not run with root privileges. That has no other means, it is not about who can be sender nor recipient (course one still can limit that in particular ACL). It is only about process's user, to prevent superuser's privileges for exim. regards -- Slavko https://www.slavino.sk
