I'm now pretty much doing email by the seat of my pants. If you sent me an email in the last 24 hours, then I likely didn't read it. It all started about 17 hours ago, when I started receiving the same SPAM email over-and-over. No matter how many times I marked the email as SPAM, Gmail continued to drop the email in my Inbox. I reviewed the email's original content and each email is identical except the sending and receiving email addresses. What's new? Gmail SPAM filtering sucks and is getting worse.
I created a filter to automatically move the missed SPAM into the Trash folder. Then I went to sleep. ... I wake up in the morning and for the first time in years, I have no email in my Inbox. Nothing for 14 hours. It seems that Gmail is no longer accepting any of my email. Period. I even sent an email directly to my Gmail account and it hasn't arrived. No email in the Trash or SPAM bucket in 16 hours.
I switched my Inbox over to Yahoo! mail. Yahoo! mails interface sucks and I haven't got my invite to the beta. I also tried Hotmail and live.com, which suck even more.
I had created a filter that works very well. Maybe you already have it, but if not try the following filter:
"-to:(username@gmail.com) -from:(username@gmail.com)" (remove quotations)
Of course change the username to what yours is and place into the Has The Words field. Be sure to remove the quotations.
