如何配置 PostFix 以允許 phpmailer 通過它發送電子郵件？
我在 CentOS 上設置了 postfix，並嘗試使用 smtp 身份驗證配置 phpmailer。
只有當我將 0.0.0.0/0 放在後綴main.conf中的 mynetworks下時， Phpmailer才會起作用
mynetworks = 127.0.0.0/8, [::ffff:127.0.0.0]/104, [::1]/128, 0.0.0.0/0但是在這個執行緒中（如何配置 PostFix 以允許其他機器通過它發送電子郵件？）有人說不要把 0.0.0.0/0 放在 mynetworks 中，因為它會導致垃圾郵件問題等。
有人可以建議我應該怎麼做，讓我的伺服器遠離垃圾郵件問題，並讓 phpmailer 工作嗎？

phpmailer調試…

我可以通過在後綴中添加以下內容來修復
/etc/postfix/master.cf..smtpd_recipient_restrictions = permit_mynetworks permit_sasl_authenticated reject_unauth_destination中繼訪問被拒絕不僅適用於 PHPmailer.. 它適用於任何客戶端 Outlook、Thunderbird 等… 放置 localhost 是一種解決方法而不是完整的修復.. 例如，當 PHPmailer/web 伺服器是不同的伺服器時，它與後綴電子郵件隔離伺服器你不能把本地主機..

您應該將 phpmailer 配置為連接到
localhost，而不是機器的主機名（然後將使用其外部 IP 地址進行連接）。localhost 允許通過 postfix by 中繼郵件
mynetworks，但是當您使用主機名連接時，它是通過公共 IP 地址進行的，不允許中繼。
