Changes
+ sieve: Redirect loop prevention is sometimes ineffective. Improve existing loop detection by also recognizing the X-Sieve-Redirected-From header in incoming messages and dropping redirect actions when it points to the sending account. This header is already added by the redirect action, so this improvement only adds an additional use of this header.
- sieve: Prevent execution of implicit keep upon temporary failure occurring at runtime.
