Kitbag, oh it is, it is.
We had a particularly obnoxious staff officer. His emails all had the statutory disclaimer - these are my opinions alone etc. I set up a rule. Everything from him went straight into the Delete tray.
If it was important I would get a nice phone call from someone else.
Got back to work on Monday. Not too many emails but the machine speed was pants. If there was an attachment it could take 30-45 min to load. If there was a deadline date on the emails of Monday or earlier I simply deleted unread
