I deleted as many useless emails in my mail box that I could just to free up some space and to see what happened. It appears that now I can receive emails even with anti-spam engaged. My quota did not appear to be exceeded previously so I figured I should try deleting old messaged. I am just worried that this problem is going to happen again soon and that something else is really causing the lockout of inbound email. This is my main account and it has caused lots of grief blocking so many clients, customers and friends.
Please let me know if you see anything else that may have caused the problem from the "ls -la /var/www/web4/.spamassassin" printout that you requested.
