我无法让后缀与我们的Office 365邮件一起工作。
这里是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 这里是mail.log的错误：

我做的事情：
我怎样才能解决这个问题？
我设法弄清楚了这个问题。
Office 365中的帐户是一个共享邮件帐户。 在我的客户将账户切换到正常账户后，我们重新configuration了后缀，一切正常。
