회원가입시 어느 메일은 정상적으로 가고, 아님 아래 형식으로 옵니다. 혹 아예 오지않는 경우도 있습니다 ㅠㅠ 지금 영카트 인증서 적용해서 이용하고있고, 메일테스트시 문제없고 개인적으로 메일보내기 했을때도 문제는 없습니다.

Hi. This is the qmail-send program at ruwa64-005.fmcity.com.

I'm afraid I wasn't able to deliver your message to the following addresses.

This is a permanent error; I've given up. Sorry it didn't work out.

<*** 개인정보보호를 위한 이메일주소 노출방지 ***>:

Connected to 66.96.140.72 but greeting failed.

Remote host said: 554 bosimpinc11 bizsmtp Connection rejected. Reverse DNS for 220.73.161.15 does not exist.

I'm not going to try again; this message has been in the queue too long.
