I recently did a few transactions on bittrex and did a withdrawal a few days ago.  Last night I tried a withdrawal but never got the confirmation email.  I tried 2FA and again, never got an email to confirm 2FA.  I opened a support ticket from another email account since the active one does not seem to work  but I imagine I won't get any support until next week. 

Anyone seen this before where emails stop working?  I can receive emails from other sources but nothing seems to work going from bittrex.
