Oh no! It seems emails to (one of) my zed1.com account(s) have been boun­cing because I had exceeded my quota. I didn’t even know I had a quota! (at least one which wasn’t included in my host­ing quota) but I do. It is 50MB and yes, it was full. I have man­aged to delete all the virus/worm gen­er­ated emails with bin­ary pay­loads and released over 40MB of space. Ouch! that’s a lot of mail!
So if any­one has sent me email to my per­sonal zed1.com account in the last 24 48 hours you may want to send it again.
