I'm using mutt with gmail Oauth2 and msmtp and so my weekly(?) login has expired then something silently eats my outgoing emails. In this case the emails that I sent directly before and after went through so it seems like my login wasn't expired or everything would have been eaten. This Oauth2 transition has just been so frustrating. Am I the only person having trouble with it? regards, dan carpenter
