Postfix mta 如何配置我的后缀以使用Outlook，Thunderbird

我安装了带有后缀的VPS，我想将我的后缀和dovecot配置为供outlook、mail、thunderbird或其他客户端使用，但在配置我的邮件时，我总是从smtp服务器收到邮件用户名o密码不正确或无法连接到此smtp服务器…我尝试使用不同的组合，请给我任何建议，对不起，我是这方面的新手

这是我的postfix.conf

# TLS parameters
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = mail.kitlearn.com
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = $myhostname, mail.kitlearn.com, localhost.kitlearn.com, , localhost,kitlearn.com,brinapptics.com
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128 189.180.0.0/16
mailbox_size_limit = 0
recipient_delimiter = +
inet_protocols = all
virtual_alias_maps = hash:/etc/postfix/virtual
sender_bcc_maps = hash:/etc/postfix/bcc
mailbox_command = /usr/bin/procmail-wrapper -o -a $DOMAIN -d $LOGNAME
home_mailbox = Maildir/
smtpd_sasl_auth_enable = yes
broken_sasl_auth_clients = yes
smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination
smtp_tls_security_level = may
allow_percent_hack = no
mynetworks_style = subnet
relayhost = [mail.kitlearn.com]:587

根据您的配置，您实际上还没有定义如何对后缀进行sasl身份验证，只允许对SMTP连接进行sasl身份验证

从我的postconf-n

smtpd_sasl_auth_enable = yes
smtpd_sasl_path = private/auth
smtpd_sasl_type = dovecot

我使用dovecot作为身份验证提供者，您需要确保dovecot允许postfix从dovecot配置查询身份验证请求

service auth {
  unix_listener /var/spool/postfix/private/auth {
    group = postfix
    mode = 0666
    user = postfix
  }
  unix_listener auth-client {
    group = postfix
    mode = 0660
    user = postfix
  }
  unix_listener auth-master {
    group = vmail
    mode = 0660
    user = vmail
  }
  unix_listener auth-userdb {
    mode = 0600
    user = vmail
  }
  user = dovecot
}
userdb {
  args = /etc/dovecot/dovecot-sql.conf.ext
  driver = sql
}

然后需要进行auth配置，我的配置是通过一个mysql表进行的—示例来自/etc/dovecot/dovecot-sql.conf.ext

driver = mysql
connect = host=localhost dbname=postfixadmin user=postfixadmin password=postfixadmin
default_pass_scheme = MD5-CRYPT
password_query = SELECT username as user, password, '/home/vmail/%d/%n' as userdb_home, 'maildir:/home/vmail/%d/%n' as userdb_mail, 150 as userdb_uid, 8 as userdb_gid FROM mailbox WHERE username = '%u' AND active = '1'
user_query = SELECT '/home/vmail/%d/%n' as home, 'maildir:/home/vmail/%d/%n' as mail, 2000 AS uid, 2000 AS gid, CONCAT('*:storage=',round(quota/1024)) AS quota_rule FROM mailbox WHERE username = '%u' AND active = '1'
