在开始设置邮件服务之前,您需要准备一些必要的内容,包括:
Postfix是一种流行的邮件传输代理(MTA)软件。安装并配置Postfix将是设置邮件服务的第一步:
$ sudo apt-get install postfix
smtpd_tls_cert_file = /etc/ssl/certs/example.com.crt
smtpd_tls_key_file = /etc/ssl/private/example.com.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${queue_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${queue_directory}/smtp_scache
smtpd_tls_protocols = !SSLv2,!SSLv3
smtp_tls_protocols = !SSLv2,!SSLv3
smtpd_tls_mandatory_protocols = !SSLv2,!SSLv3
smtp_tls_mandatory_protocols = !SSLv2,!SSLv3
smtpd_tls_exclude_ciphers = aNULL, MD5, DES, ADH, RC4
smtp_tls_exclude_ciphers = aNULL, MD5, DES, ADH, RC4
smtpd_tls_security_level = may
tls_preempt_cipherlist = yes
smtpd_recipient_restrictions = permit_sasl_authenticated, permit_mynetworks, reject
message_size_limit = 52428800
mailbox_size_limit = 52428800
virtual_mailbox_limit = 52428800
virtual_mailbox_base = /var/mail/vmail
virtual_uid_maps = static:5000
virtual_gid_maps = static:5000
virtual_mailbox_domains = example.com
virtual_transport = lmtp:unix:/var/run/dovecot/lmtp
Dovecot是一种流行的邮件传输软件。安装并配置Dovecot服务将是设置邮件服务的第二步:
$ sudo apt-get install dovecot-core dovecot-imapd dovecot-lmtpd dovecot-mysql dovecot-sieve
# Postfix smtp-auth
unix_listener /var/spool/postfix/private/auth {
mode = 0666
user = postfix
group = postfix
}
service lmtp {
unix_listener /var/run/dovecot/lmtp {
master {
user = vmail
group = vmail
}
mode = 0660
user = vmail
group = vmail
}
}
现在您已经完成了邮件服务的安装和配置工作,下一步将是创建一个或多个邮件账户:
CREATE USER vmail WITH PASSWORD 'mypassword';
GRANT CONNECT ON DATABASE maildb to vmail;
CREATE TABLE mailbox (
id serial PRIMARY KEY,
username varchar(255) NOT NULL,
password varchar(255) NOT NULL,
maildir varchar(255) NOT NULL,
quota bigint DEFAULT NULL
);
CREATE TABLE alias (
id serial PRIMARY KEY,
address varchar(255) NOT NULL,
goto text DEFAULT NULL,
domain varchar(255) NOT NULL,
created timestamp DEFAULT now() NOT NULL,
modified timestamp DEFAULT now() NOT NULL
);
sudo mkdir /var/mail/vmail
sudo chown vmail:vmail /var/mail/vmail
现在您可以添加电子邮件账户和别名了:
sudo mkdir /var/mail/vmail/example.com/user1
sudo chown -R vmail:vmail /var/mail/vmail/example.com/user1
sudo chmod -R 700 /var/mail/vmail/example.com/user1
现在,您已经完成了所有设置工作。现在,您可以使用任何电子邮件客户端或网络邮件接口来测试您的设置,例如Gmail或Outlook:
