[root@mail ~]# vim /etc/dovecot.conf 20 #protocols = imap imaps pop3 pop3s --默认全开 22 protocols = pop3 [root@mail ~]# netstat -tupln |grep 25 tcp 0 0 0.0.0.0:25 0.0.0.0:* LISTEN 4659/sendmail: acce udp 0 0 :::43725 :::* 3191/avahi-daemon: [root@mail ~]# netstat -tupln |grep dov tcp 0 0 :::993 :::* LISTEN 4803/dovecot tcp 0 0 :::995 :::* LISTEN 4803/dovecot tcp 0 0 :::110 :::* LISTEN 4803/dovecot tcp 0 0 :::143 :::* LISTEN 4803/dovecot [root@mail ~]# grep 993 /etc/services imaps 993/tcp # IMAP over SSL imaps 993/udp # IMAP over SSL imap4-ssl 585/tcp # IMAP4+SSL (use 993 instead) imap4-ssl 585/udp # IMAP4+SSL (use 993 instead)
[root@mail ~]# grep 995 /etc/services pop3s 995/tcp # POP-3 over SSL pop3s 995/udp # POP-3 over SSL
[root@mail ~]# service dovecot restart
[root@mail ~]# chkconfig dovecot on 3.3客户端使用sendmail发送接收mail 1. 配置outlook 27-3 [root@mail ~]# mail user1 Subject: hhh gfgfg . Cc: 27-4 3.4使用Outlook发信 27-5
