According to Kakao, from around 9:12 a.m. to 4 p.m. that day, delays in sending and receiving emails were observed in the Daum mail service.
Daum posted a notice on the mail homepage stating that there were "delays in receiving all external domain emails," "delays or failures in sending some emails," and "intermittent connection failures with imap and smtp."
