I'm boggled by this one. I use Thunderbird 128.2.0esr (64-bit) on Fedora and Gnome. I use it as my mail interface and my POP server is Gmail. Earlier this week, when I pulled up the list of emails in my inbox, I noticed that emails from GitHub were all "From" one apparently random person. If I click on the email and look at the mail in the preview pane, it too has the incorrect "From" value. However, if I reply to or forward the email, it will have the correct "From" address. What's stranger, is I also get emails from Jira and other bots. They two have the same issue but with another person. For instance, all of my emails from GitHub now come from "John Smith". All my Jira emails come from "Elizabeth Doe (Jira)". The people they are coming from are people I receive those types of emails from, but not every single email. I've rebooted, and still the same problem, and still the same wrong people in the From field for GitHub, Jira, and others. Any ideas?
