Question

我已经在我的1和1 VPS上安装了带有POSTFIX的ubuntu 14.04，我在向自己的电子邮件发送电子邮件时遇到问题。

当我发送电子邮件时：

outlook.com RECEIVED
yahoo.com RECEIVED
Gmail.com RECEIVED
example.co.uk（1and1 mail）NOT RECEIVED

main.cf

# 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 (Ubuntu)
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

# See /usr/share/doc/postfix/TLS_README.gz in the postfix-doc package for
# information on enabling SSL in the smtp client.

smtpd_relay_restrictions = permit_mynetworks permit_sasl_authenticated defer_unauth_destination
myhostname = example.co.uk
alias_maps = hash:/etc/aliases
alias_database = hash:/etc/aliases
mydestination = localhost
relayhost = 
mynetworks = 127.0.0.0/8 [::ffff:127.0.0.0]/104 [::1]/128
mailbox_command = 
mailbox_size_limit = 0
recipient_delimiter = +
inet_interfaces = all
myorigin = /etc/mailname
inet_protocols = all

Answer 1

当我通过mailq命令检查了我的邮件队列时，我收到了错误：(delivery temporarily suspended: host mx01.1and1.co.uk[xxx.xx.xxx.xx] refused to talk to me: 554-kundenserver.de (mxeue105) Nemesis ESMTP Service not available 554-No SMTP service 554 invalid DNS PTR resource record, IP=xxx.xxx.xxx.xxx所以我刚刚添加了一个PTR（反向DNS）条目。

现在它的工作：）

POSTFIX不仅仅向1and1主电子邮件发送电子邮件
