▷ 질문내용 :

이전까지는 잘 쓰다가 갑자기 메일이 송수신이 되지 않으면서 위와 같은 return 메일이 도착을 합니다

또한, 서버컴퓨터에 설치되어 있는 nmail에 에러가 발생했다고 나오면서

C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\1\WERb824.dir00\Nmail.exe.mdmp

C:\DOCUME~1\ADMINI~1\LOCALS~1\Temp\1\WERb824.dir00\appcompat.txt

위와 같은 에러가 발생했다고 뜨구요. (서버컴퓨터의 OS는 win2003입니다)

어떤 문제가 있고 어떻게 해결해야 하는지 부탁드립니다.
