我正在尝试让 postfix 通过我的 smtp 帐户与另一个电子邮件提供商（在本例中为 lavabit.com）发送电子邮件
我收到错误
无法识别收件人。中继访问被拒绝
这让我认为它试图将电子邮件发送到该外部 smtp 但被拒绝，因为该地址没有帐户，而不是使用我的帐户登录进行身份验证并以该帐户（我）的身份通过外部 smtp 发送电子邮件。
我的 sasl_passwd 文件内容如下：
mail.lavabit.com [email protected]:password
我的 master.cf 内容如下：
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname
smtpd_banner = $myhostname ESMTP $mail_name (Debian/GNU)
biff = no
# appending .domain is the MUA's job.
append_dot_mydomain = no
# Uncomment the next line to generate "delayed mail" warnings
#delay_warning_time = 4h
readme_directory = no
# TLS parameters
smtpd_tls_cert_file = /etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file = /etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache

# information on enabling SSL in the smtp client.
myhostname = vps.httech.com.au

sender_dependent_default_transport_maps = hash:/etc/postfix/relayhost_maps
debug_peer_list = lavabit.com
transport_maps = hash:/etc/postfix/transport
relayhost = mail.lavabit.com
虽然我最终想用它，但此刻relayhost_maps它是空的，只转发一个地址的电子邮件而不是全部。
答案1
好的，事实上没有通过身份验证的原因是我需要：
smtp_sasl_auth_enable = yes
不只是：
smtpd_sasl_auth_enable = yes
因为 smtp_sasl_auth_enable 适用于 postfix 的 smtp 客户端部分（postfix 发送电子邮件）
smtp_sasl_auth_enable 用于 postfix 的 smpt 服务器部分（postfix 接收电子邮件）
