This is incident # 140604-031419. Starting this morning I haven't been able to send yahoo emails through Thunderbird. Instead a security exception box pops up, saying: "You are about to override how Thunderbird identifies this site. Legitimate banks, stores, and other public sites will not ask you to do this. This site attempts to identify itself with invalid information. Outdated information. Certificate is not currently valid. It is impossible to verify whether this identity was reported lost or stolen."

After clicking on "View," I saw that the smtp.mail.yahoo.com security certificate had supposedly expired today, June 4, 2014. Is it possible yahoo forgot to renew the certificate (evidently that really did happen in 2008)?

How can I start sending emails through that account again without jeopardizing security?

Yahoo screwed up. It is up to you to decide whether it's safe to create an exception and send the message anyway, or wait until they fix the cert.

You could use webmail as a workaround though.

Not that it makes you feel better, but you're not alone. https://answers.yahoo.com/question/index?qid=20140604112909AAwFdLO

Thx, Christ1.

The link doesn't solve the problem, but misery DOES love company!

Anybody know how to contact Yahoo to REMIND them to renew their security cert?

Hey! Thx, Matt!

Got up this morning and the T-bird (or more likely, the YAHOO) issue had been resolved. I also found threads showing many other people had experienced my problem at the same time (good to know it wasn't my imagination or less-than-excellent tech skills!).

For someone like me, who didn't grow up with computers, it's amazing how quickly we became dependent upon technology to keep in touch. I have 5 grown kids (plus kids-in-law and grandkids) currently living in Korea, Japan, Boston, Denver, Raleigh, and Rochester, NY. If we didn't have email and texting, etc., being a daily part of each other's lives would be virtually impossible. (I know this seems all too obvious to those of you who grew up in the computer era, but to many of us older folks it STILL sometimes seems like a daily miracle!) It was really AWFUL to feel so out of touch yesterday!

Thx again for the help. Spring has finally sprung (at least here in upstate NY), so hope you're enjoying the sense of renewal it always seems to bring!
