smtp server certificate expiration

No, I see it too, and I'm using Thunderbird.

We are having the identical problem with the expired smtp.cox.net certificate. We are located in the Palos Verdes service area.

Yes, I have that as well on my husbands computer as he uses Outlook on his Mac.   I use Apple Mail on my  Mac, and I am getting a similar indication .  Also, for the last few weeks, on both my iPhone and my Mac, I have been getting the response Cannot connect to the outgoing Mail Server for SMTP at smtp.Cox.net. I have been getting this on my Mac for at least 2 weeks and have to keep changing the port between 110 & 995 and then my mail will send.  Its VERY annoying.  Also, on my phone, which is very annoying.  I called Cox, and the tech I got had NO CLUE.  I asked to be transferred to the next tier, and I got cut off.  I was just tired of being on the phone, so I didn't call back.  Ughhhhhh

we are in Scottsdale AZ

Can the COX MODERATOR PLEASE REPLY TO THIS????  Thanks 

Hello everyone,

There is a known certificate issue that we are currently working on fixing. We do not have an ETA at this time. I apologize for this inconvenience. 

Thanks,
