some e-mails not received

[lew]

I am not receiving some emails from people I have received from in the past
or some new senders-all are in my contacts. This just started in the last 30
days. What could cause this?

Does your mail provider have any filters on its web server?

Log in to their website and check the Junk/Spam/Deleted folders.

Are the expected messages in that online inbox?

Are any of these senders getting a non-delivery notice when they send to you?

A few large mail providers like AOL, Hotmail, and Yahoo will drop suspected
spam silently without sending back a non-delivery notice to the sender.

The senders are not getting a non-delivery notice. Is there any way you know
of that I can fix this? I have AT&T Yahoo.

Make sure those emails aren't getting trapped in your webmail spam folder.
Go to http://mail.yahoo.com and login with your AT&T credentials.
Check the Spam folder.
