I am really getting frustrated with this. I don't want to delete the catchall yet until I fathom out all the stupid names I have used in the past - I even used gas@mydomain when I email the gas company - there might be others !!
So I had set up filters at Account Level Filter so some of the words in subject line, body or to certain addresses I don't use, are filtered to discard. (which sometimes reverts back to /dev/null for some reason)
But they are all now getting filtered into my main email and not being discarded. I now have a few hundred emails in my main account all with rude words in them. I view them through mailwasher so can delete them without opening them but it is taking a long time.
What am I doing wrong

the help pages are not too helpful when it goes wrong - I thought I was doing what they said do.
