Email not working

I need some assistance with my email settings. I have entered all my details correctly but it wont update my password

i tested the email setting last night and it worked perfectly , but now it wont send any mail
i have receive countless errors

you need to give more details with screenshots and most importantly what error you are receiving.

Are you using the in-built SMTP or custom SMTP? It sounds like custom. If so, and you tested it successfully and have not changed any settings, the problem is with your SMTP provider.

What do you mean by “it won’t update my password?” How do you know? Why do you think this is the problem? If it won’t update, that means you must be trying to change things since the successful test. Did you change your email password?
