우분투 sendmail전송시 421 4.3.0 collect: Cannot write ./dfv5BA2EBS010579 (bfcommit, uid=0, gid=114): No such file or directory 발생시 조치사항
sendmail및 postfix 설치후 "telnet localhost 25"를 입력하여 메일을 전송을 테스트 할때 아래와 같은 오류가 발생할 수 있다.
sendmail이 특정위치에 쓰기 권한이 없어서 발생하는 문제이므로
root@gsda4:/root# ls -al /tmp /var/tmp /var/spool/mqueue /var/mail를 이용하여 권한을 확인하여 변경해준다.
특히 /var/tmp폴더의 권한을 잘 확인하여 변경해준다.
root@gsda4:/root# ls -al /var/tmp
/var/tmp:
total 8
drwxr-xr-x 2 root root 4096 Apr 13 2016 .
drwxr-xr-x 14 root root 4096 May 22 14:46 ..
인경우 "root@gsda4:/root# chmod 661 /var/tmp"을 실행하여 아래 처럼 변경시켜준다.
root@gsda4:/root# ls -al /var/tmp
total 8
drw-rw---x 2 root root 4096 Apr 13 2016 .
drwxr-xr-x 14 root root 4096 May 22 14:46 ..
