HI all. This is a good one. I recently got a MAC, my first one, so dont know much about it. I installed thunderbird and can receive via IMAP but cant send via SMTP. I have smtp setup EXACTLY how it is on my windows PC which works. When I hit send on a message, it immediately comes back with "Sending of the message failed. The message could not be sent because the connection to Outgoing server (SMTP) <maileserver.com> timed out. Try again. This message comes back immediately, as in .000001 second. This particular mail server I own and is on my network, and checking the logs, the request never even gets to the server, so its not a server issue. (Again, it works for all my other devices and other clients). server info, password etc are correct. I tried deleting the account and recreating it but no go. From a command tool, I can telnet to my mail server on port 25 and it answers and I can interact. If I use the built in mac mail client, it works fine. So this is definitely a thunderbird issue from what I can tell. Thunderbird 143.0.1 (aarch64) on 26.0.1 (25A362) Any tips appreciated, Im ready to take a bath with a toaster. Thank you!
