sorry bro i have checked again and im banned by fail2Ban :face_with_open_eyes_and_hand_over_mouth:


When a new client migrates to my email server, and configures several outlooks, the whole office will be banned for sure.

Try to whitelist the office IP in fail2ban first.

Yes thanks I have whitelisted my office IP. :v:
