Look at it again:
cat filelist.* filelist1 | sort | uniq -u > filelist
All of the lines are in filelist1, but only some are in filelist.*
And why exactly would you want to add the contents of filelist.webmail (for example) to filelist?
If something's in filelist.webmail then it does not belong in filelist.
