I just tried, I've upgraded my laptop to Trixie but I rarely send email from it. Answer was yes, at first. My "Sending" settings were out of date but adding current settings and setting that as default didn't help. Maybe there was some account setting hidden somewhere trying to use old settings, probably in identity settings. Error message didn't help either, it just said bad credentials, not what it had tried and where... Removing all the other outgoing settings fixed sending. Sent and Trash folders needed a little updating too.
