我无法让 Postfix 与我们的 Office 365 邮件配合使用。
这是 main.cf 文件：
smtpd_banner = $myhostname ESMTP $mail_name (Ubuntu)
biff = no
append_dot_mydomain = no
readme_directory = no
smtpd_tls_cert_file=/etc/ssl/certs/ssl-cert-snakeoil.pem
smtpd_tls_key_file=/etc/ssl/private/ssl-cert-snakeoil.key
smtpd_use_tls=yes
smtpd_tls_session_cache_database = btree:${data_directory}/smtpd_scache
smtp_tls_session_cache_database = btree:${data_directory}/smtp_scache
smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = signa-01
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
myorigin = /etc/mailname
mydestination = signa.com, signa-01, localhost.localdomain, localhost
relayhost = [smtp.office365.com]:587
mynetworks = 127.0.0.0/
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = loopback-only
inet_protocols = all
smtp_use_tls = yes
smtp_always_send_ehlo = yes
smtp_sasl_auth_enable = yes
smtp_sasl_password_maps = hash:/etc/postfix/sasl_passwd
smtp_sasl_security_options = noanonymous
smtp_sasl_tls_security_options = noanonymous
smtp_tls_security_level = encrypt
smtp_generic_maps = hash:/etc/postfix/generic
smtp_tls_CAfile = /etc/ssl/certs/ca-certificates.crt
smtp_sasl_mechanism_filter = login
以下是来自 mail.log 的错误：
Jul 14 11:54:59 signa-01 postfix/error[17234]: DB0D6184D29: to=<[email protected]>, relay=none, delay=0.03, delays=0.02/0/0/0.01, dsn=4.7.3, status=deferred (delivery temporarily suspended: SASL authentication failed; server smtp.office365.com[132.245.25.2] said: 535 5.7.3 Authentication unsuccessful)
我做过的事情：
- 我用了本教程使用 365 配置 Postfix
- 我已验证 /sasl_passwd 中的用户名和密码正确
- 我尝试将 smtp_sasl_mechanism_filter = login 添加到 main.cf
我该如何解决这个问题？
答案1
我已设法弄清楚了这个问题。
Office 365 里面的账户是共享邮件账户，我的客户把账户切换成普通账户后，我们重新配置了 postfix，一切正常。
