Mail is holding on to cached account settings. So now no matter how many times I delete the email account from the Systems Setting online account the SMTP settings wont clear when I re-enter the account.
Also in the Mail app the Accounts settings panel is too long(vertically) so you can't see the apply/OK, cancel buttons.
Well, you can see the content in the Pantheon Mail folder with:
ls .local/share/pantheon-mail/
You going to see a folder with the names of your e-mail accounts, something like my_name@example.com, so you can delete that folder with:
rm -rf .local/share/pantheon-mail/my_name@example.com
Of course you can delete completely the folder of Pantheon Mail:
rm -rf .local/share/pantheon-mail/
And that is all, i suppose that is what you wanna to do.
