請問張SIR
有一家客戶無法寄信到我這 ,我在mail.log內有看到退信內容,內容如下:
Feb 11 17:37:22 mailsvr postfix/smtps/smtpd[22742]: disconnect from 85sky-tower.com[60.249.152.222]

Feb 11 17:38:51 mailsvr postfix/smtps/smtpd[24106]: disconnect from 85sky-tower.com[60.249.152.222]

这里显示的是 postfix/smtps，应该是 465 端口，为何这个客户会将邮件投递到 465 而不是 25？

張SIR ,
至於為何他是投遞到465我就不出清楚了
但我有試著在master.cf 裡面
原本-o smtpd_client_restrictions=permit_sasl_authenticated,reject
改成-o smtpd_client_restrictions=permit_sasl_authenticated,permit_mynetworks
然後對方就能寄信進來了，請問這樣改會有甚麼問題嗎?

有问题。

1: 所有邮件服务器都是用 25 端口通讯，不是 587 或 465。寄到 465 就是错误，因为不符合 RFC 规范。或者你可以尝试联系对方的管理员来解决他的服务器问题。
2: 这个修改不是不可以，但是你应该在最后加上 ',reject'。

回到最根本的问题：MTA 通过 587/465 端口来递送邮件是错误的。
