(Dont know if the image works, but you cant see a line in the Sent Email graphic)
(As I only can show one picture, i cannot show the one with the max Sendmail Daily Quota)
My Sendmail Daily Quota is not refreshing, but it has already been 1.5 days.
Mailing quote is refreshed once at 24 hours. Maybe no e-mails have been sent from your site recently?
It has been reset right now, but right now I have problems connecting. It says:
ERR_NAME_NOT_RESOLVED
