我最近将一些网站从旧服务器迁移到了 DigitalOcean 上具有相同配置的新服务器。
除了 php mail() 函数不能发送电子邮件以外，网站运行良好。
php 配置与旧服务器相同，我看不出问题出在哪里。
后缀配置是：
$ postconf -n
alias_database = hash:/etc/aliases
alias_maps = hash:/etc/aliases
command_directory = /usr/sbin
config_directory = /etc/postfix
daemon_directory = /usr/libexec/postfix
data_directory = /var/lib/postfix
debug_peer_level = 2
html_directory = no
inet_interfaces = localhost
inet_protocols = ipv4
mail_owner = postfix
mailq_path = /usr/bin/mailq.postfix
manpage_directory = /usr/share/man
mydestination = $myhostname, localhost.$mydomain, localhost, $mydomain
mydomain = MY_DOMAIN
myhostname = MY_DOMAIN
myorigin = $mydomain
newaliases_path = /usr/bin/newaliases.postfix
queue_directory = /var/spool/postfix
readme_directory = /usr/share/doc/postfix-2.6.6/README_FILES
sample_directory = /usr/share/doc/postfix-2.6.6/samples
sendmail_path = /usr/sbin/sendmail.postfix
setgid_group = postdrop
unknown_local_recipient_reject_code = 550
进行测试时，邮件日志输出如下：

你能帮助我吗？
谢谢。
答案1
与我的服务器提供商（DigitalOcean）交谈后，我发现他们阻止了从我的服务器发出的电子邮件。
问题已经解决了。
谢谢。
