Hello! Apologies if this isn't the right place to ask, but it's not clear what exactly is at fault here so I thought I'd at least start on this list. I updated my system yesterday with pacman -Syu, and now Claws is claiming that pop.gmail.com is sending an invalid certificate whenever Claws tries to connect to fetch mail. I've not accepted the invalid certificate. This is the text of the dialog box that pops up: --8<-- Certificate for pop.gmail.com has changed. Certificate is for invalid2.invalid, but connection is to pop.gmail.com. You may be connecting to a remote server. Do you want to accept it? Signature status: Self-signed certificate.
