메일 발송 루틴이고요.

A PHP Error was encountered

Severity: Warning

Message: fsockopen(): SSL operation failed with code 1. OpenSSL Error messages: error:140770FC:SSL routines:SSL23_GET_SERVER_HELLO:unknown protocol

Filename: libraries/Email.php

Line Number: 1689

에러 메세지입니다.

네이버 587포트로 소켓연결이 안되네요  ㅡㅡ;;;
465포트로 변경하면 발송 잘됩니다.
프로토콜도 ssl로 했구요.
