2. 환경설정 파일 설정

[root@bban2 ~]# vi /etc/dovecot.conf

18 # Protocols we want to be serving: imap imaps pop3 pop3s
19 # If you only want to use dovecot-auth, you can set this to "none".
20 #protocols = imap imaps pop3 pop3s
21 protocols = imap pop3

23 # IP or host address where to listen in for connections. It's not currently
24 # possible to specify multiple addresses. "*" listens in all IPv4 interfaces.
25 # "[::]" listens in all IPv6 interfaces, but may also listen in all IPv4
26 # interfaces depending on the operating system.
27 #
28 # If you want to specify ports for each service, you will need to configure
29 # these settings inside the protocol imap/pop3 { ... } section, so you can
30 # specify different ports for IMAP/POP3. For example:
31 #   protocol imap {
32 #     listen = *:10143
33 #     ssl_listen = *:10943
34 #     ..
35 #   }
36 #   protocol pop3 {
37 #     listen = *:10100
38 #     ..
39 #   }
40 #listen = [::]
41 listen = *

136 # User to use for the login process. Create a completely new user for this,
137 # and don't use it anywhere else. The user must also belong to a group where
138 # only it has access, it's used to control access for authentication process.
139 # Note that this user is NOT used to access mails. <doc/wiki/UserIds.txt>
140 #login_user = dovecot
141 login_user = dovecot

206 #   mail_location = maildir:~/Maildir
207 #   mail_location = mbox:~/mail:INBOX=/var/mail/%u
208     mail_location = mbox:~/mail:INBOX=/var/mail/%u   - 사용자 별로 mbox 사용
209 #   mail_location = mbox:/var/mail/%d/%1n/%n:INDEX=/var/indexes/%d/%1n/%n
 
508 protocol imap {
509   # Login executable location.
510   #login_executable = /usr/libexec/dovecot/imap-login
511   login_executable = /usr/libexec/dovecot/imap-login - imap-login 데몬 실행 파일 위치를 지정한다.

523   #mail_executable = /usr/libexec/dovecot/imap
524   mail_executable = /usr/libexec/dovecot/imap

575 protocol pop3 {
576   # Login executable location.
577   #login_executable = /usr/libexec/dovecot/pop3-login
578   login_executable = /usr/libexec/dovecot/pop3-login  - pop3-login 데몬 실행 파일 위치를 지정한다.
 
580   # POP3 executable location. See IMAP's mail_executable above for examples
581   # how this could be changed.
582   #mail_executable = /usr/libexec/dovecot/pop3

684 # Executable location
685 #auth_executable = /usr/libexec/dovecot/dovecot-auth
686 auth_executable = /usr/libexec/dovecot/dovecot-auth - 인증 실행

3. devocot 확인

-------------------------------------------------------------------

3-1. 프로그램 -> 인터넷  -> 전자메일 선택

-------------------------------------------------------------------

3-2. 에볼루션 설정 -  POP3, IMAP 형식 중 POP3 형식으로 설정해본다.

그리고 메일 보내기 해보고 보내기 받기 하면 메일이 온다. 이때 해당 사용자의 패스워드를 입력한다.

메일 주고 받기가 성공했다면  guest 사용자에게 메일을 보내본다.

[root@bban2 ~]# mail guest@bban2.co.kr
