I've been using Yahoo mail for 10+ years with no problems. Lately it seems some emails with attachments don't make it through - to my Yahoo account. I first noticed it a week ago. I sent a link from my work Outlook to my home PC - the link was in an attachment. It included some information I needed to access (to telecommute). Later that day I checked Yahoo and the email had not arrived. So, I re-sent it to Yahoo and Hotmail. It arrived at Hotmail but not Yahoo. My Yahoo address is not on it's own spam list and I have no filters active. I get no 'undeliverable' message. And, some of my test emails, with attachments, have made it to my account. Any ideas?
