Is encrypt a MySQL data type?
I am sorry.its my fault.Encrypt not mysql data type.Password field type varchar but password field type function is encrypt and postfix use TLS. for example: Assuming that password is abc,it has been stored like oZBhlIb1J0iH. in password field.If i dont use encrypt function,"abc" store like "abc" in password field.. if i dont use encrypt function for password field type(varchar),sasl2 authentication ok but courier has configured like below; MYSQL_CRYPT_PWFIELD password so couirer doesnt work without encrypt function to password field type. if i change courier configuration like below: MYSQL_CLEAR_PWFIELD password everything is ok but i dont want to directly see password on password field. In short, If use encrypt | Sasl2-sql authentication | Courier authmysql authentication YES -> NO YES NO -> YES YES How can i solve this problem with use encrypt function to password field.
