收到错误“中继访问被拒绝”
在 Outlook 中，在 Ubunut LTS 上为 smtp 设置端口 587，为 imap 设置端口 993。
我的配置是：
root@server:~# postconf -n
append_dot_mydomain = no
biff = no
broken_sasl_auth_clients = yes
config_directory = /etc/postfix
disable_vrfy_command = yes
dovecot_destination_recipient_limit = 1
inet_interfaces = all
mailbox_size_limit = 0
message_size_limit = 0
mydestination =
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mynetworks_style = host
myorigin = /etc/mailname
queue_directory = /var/spool/postfix
readme_directory = no
recipient_delimiter = +
relayhost =
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtp_use_tls = yes
smtpd_banner = $myhostname ESMTP $mail_name
smtpd_delay_reject = yes

smtpd_tls_security_level = may
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtpd_use_tls = yes
virtual_alias_maps = mysql:/etc/postfix/mysql-virtual-alias-maps.cf
virtual_mailbox_base = /var/vmail
virtual_mailbox_domains = mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf
virtual_mailbox_limit = 0
virtual_mailbox_maps = proxy:mysql:$config_directory/mysql-virtual-mailbox-maps.cf
virtual_transport = dovecot
答案1
添加类似这样的内容到你的main.cf：
smtpd_relay_restrictions = permit_sasl_authenticated,
permit_mynetworks,
reject_unauth_destination
答案2
更正
smtpd_sasl_type = cyrus
到
smtpd_sasl_type = dovecot
