True, but it's far more common that it's bad content sent from a forged address. Not sending backscatter is a clear best pracice these days.
More experienced admins might set up a quarantine/release system (amavisd-new supports this), but such a system is too complex for a default. I think no backscatter is a good default approach. It's easy enough to change for people experienced enough to manage the consequences. ** Changed in: amavisd-new (Ubuntu) Status: Incomplete => Confirmed -- Default Ubuntu configuration is backscatter source in Jaunty https://bugs.launchpad.net/bugs/360689 You received this bug notification because you are a member of Ubuntu Server Team, which is subscribed to amavisd-new in ubuntu. -- Ubuntu-server-bugs mailing list Ubuntu-server-bugs@lists.ubuntu.com Modify settings or unsubscribe at: https://lists.ubuntu.com/mailman/listinfo/ubuntu-server-bugs
