I don't know if it's new with this version, but I am currently having a strange issue with sending email using this version with my iCloud account. The app acts like it's sending messages, and they show up in my Sent folder on my desktop, in the web client, etc., but the messages are apparently never sent (never received, not even when sent to the same account I'm sending from). Sending from my desktop computer with the same server settings works just fine. Thoughts?
