Thunderbird refuses to pass the verification step whenever I try to add the mailbox that sits behind my Cloudflare-managed domain. I’m setting the account up as IMAP, yet the test still fails and the client will not connect. I’d like you to: • Review the current Cloudflare records that relate to mail (MX, SPF, DKIM, DMARC if relevant) and confirm they align with what Thunderbird expects for an IMAP setup. • Walk me through (or document) the exact server names, ports, and security settings I should enter in Thunderbird so the account finally verifies. • Stay with me until a fresh Thunderbird profile can both send and receive messages without errors. If you’ve solved this exact combination of Cloudflare + Thunderbird before and can get me running quickly, please let me know your plan and an estimated timeline.
