Q: El Capitan Mail flashing problem
I just upgraded to El Capitan and tried to compose a message in Mail. After I clicked Send, the Compose window started flashing. I closed the program and relaunched, but the problem persisted. I finally managed to delete the email from my Outbox in between flashes (wasn't easy). I tried to compose another email, but the same issue occurred. Is this a bug? This makes Mail unusable.
MacBook Pro with Retina display, OS X El Capitan (10.11)

Thanks everyone. I checked and the SMTP settings did get obliterated and replaced by settings from an old account. I ended up removing all my Gmail accounts and re-adding them, using the built in Google Account option. I tested sending an email and it worked without any flashing. It's good that I use IMAP and not POP. I don't know if non-Gmail users are running into this issue. But for now, problem fixed! I have to say I am a little disappointed that this bug was not caught (and fixed) during the extensive testing and the many public betas.
