I tried to send an e-mail to my wifes cell phone, which I have done before, and not only did it fail, but every few hours I get another failure message.

I deleted the failing e-mail from my sent folder, but of course this did not help. I have gotten about 5 failure messages from the mail-daemon over 2 days, so it is annoying.

Incidentally, my wife does not receive any e-mails I send to her Thunderbird account - she used to. She receives e-mails from many other people, and I have no problem sending e-mails to other recipients! There is no failure messages on the e-mails I send to her Thunderbird account. We both have a Comcast e-mail address.

Chosen solution

The failure message is from your provider and should include the reason.

There is no such thing as a Thunderbird account so no idea what you mean there. Sounds like Comcast is your provider and that is where your account would be. Thunderbird is email client software running on your computer and not a provider.

Comcast blamed it on Verizon, my wife's mobile phone service provider, but in fact I stopped getting the temporary failure messages.
