You must be mistaken. The only plausible issue is smtputf8 messages already in the queue, I don't how they're handled when smtputf8 is disabled with the message still queued. > I'll try downgrading the main mail server to 2.x and see if that works. That release also has no smtputf8 support, so it is difficult to see why that might be better than 3.0.x with smtputf8 disabled. -- Viktor.
