Postfix 上的 SASL 身份验证失败，作为带有 office365 的中继服务器
SASL Authentication Failed on Postfix as relay server with office365
我正在将 postfix 服务器设置为中继到 office 365 中的帐户。
我配置主文件/etc/postfix/main.cf如下：
relayhost = [smtp.office365.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_mechanism_filter = login
smtp_use_tls = yes
smtp_always_send_ehlo = yes
#smtp_tls_security_level = secure
smtp_tls_security_level = may
smtp_tls_mandatory_protocols = TLSv1
smtp_tls_mandatory_ciphers = high
smtp_tls_secure_cert_match = nexthop
#Check that this path exists -- these are the certificates used by TLS
smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt
#Set the sasl options
smtp_sasl_security_options = noanonymous
sender_canonical_maps = regexp:/etc/postfix/sender_canonical
还做了一个sasl_password文件：
[smtp.office365.com]:587 username@domain.com:thepassword
并应用了 postmap 命令：
postmap sasl_passwd
消息未送达，日志显示下一条消息
Aug 29 11:22:04 relaysmtp postfix/error[13501]: 0CA2C82CD1: to=<username@domain.com>, relay=none, delay=6538, delays=6538/0/0/0.01, dsn=4.7.3, status=deferred (delivery temporarily suspended: SASL authentication failed; server smtp.office365.com[40.102.32.146] said: 535 5.7.3 Authentication unsuccessful [PT1sdsaoPP.akpr0.prod.outlook.com])
CentOS 6.10中的postfix版本为3.2.3
我将 Postfix 的日志配置为更详细的输出；然后我用另一台主机的 Telnet 命令进行了测试。
我将粘贴原语和后缀的输出，用符号分开：

似乎 postfix 甚至没有使用由 postmap 生成的 sasl_passwd.db 文件。
我错过了什么？
感谢帮助
我尝试使用另一个帐户，身份验证有效，并且可以传送消息。
当您重新加载 postfix 时，您能看到 /var/log/mail 或 postfix 的邮件日志文件中缺少任何内容吗？在某些情况下，它会告诉您缺少什么。如果你只看到它重新加载正常，那么你可能必须检查 master.cf 文件并尝试注释掉：
#-o smtp_fallback_relay=
您还可以通过 "postconf -n"
查看什么是实时后缀配置
所做的任何更改都需要 "postmap filename" 重新生成数据库文件并重新加载后缀。不同于alias.db，使用"postalias alias"重新生成alias.db
我正在将 postfix 服务器设置为中继到 office 365 中的帐户。
我配置主文件/etc/postfix/main.cf如下：
relayhost = [smtp.office365.com]:587
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_mechanism_filter = login
smtp_use_tls = yes
smtp_always_send_ehlo = yes
#smtp_tls_security_level = secure
smtp_tls_security_level = may
smtp_tls_mandatory_protocols = TLSv1
smtp_tls_mandatory_ciphers = high
smtp_tls_secure_cert_match = nexthop
#Check that this path exists -- these are the certificates used by TLS
smtp_tls_CAfile = /etc/pki/tls/certs/ca-bundle.crt
#Set the sasl options
smtp_sasl_security_options = noanonymous
sender_canonical_maps = regexp:/etc/postfix/sender_canonical
还做了一个sasl_password文件：
[smtp.office365.com]:587 username@domain.com:thepassword
并应用了 postmap 命令：
postmap sasl_passwd

似乎 postfix 甚至没有使用由 postmap 生成的 sasl_passwd.db 文件。
我错过了什么？
感谢帮助
我尝试使用另一个帐户，身份验证有效，并且可以传送消息。
当您重新加载 postfix 时，您能看到 /var/log/mail 或 postfix 的邮件日志文件中缺少任何内容吗？在某些情况下，它会告诉您缺少什么。如果你只看到它重新加载正常，那么你可能必须检查 master.cf 文件并尝试注释掉：
#-o smtp_fallback_relay=
您还可以通过 "postconf -n"
查看什么是实时后缀配置所做的任何更改都需要 "postmap filename" 重新生成数据库文件并重新加载后缀。不同于alias.db，使用"postalias alias"重新生成alias.db
