I started using Gmail back in 2004 and needless to say I have millions of emails and it's not easy to clean it up.What's the most efficient way to do clean up my Gmail? (It's not like I can sort by size and see which emails are taking most of space.)* UPDATE *after using certain label, such as this:label:freebsd-questions -label:starredI hit Delete and a minute later I saw this:Oops the system encountered a problem (#793) - Retrying in 1sand when I opened another tab to Gmail I saw this: Gmail by Google Temporary Error (500)   Were sorry, but your Gmail account is temporarily unavailable.
