Windows Server 2022的IIS SMTP模組又有一個小bug

如果你是用 win server 2022，就會出現掛掉無法編輯使用的狀況，不知為何win server 2022 會有這個奇怪的bug

請遵照下面步驟修改，就可以正常運作

1. Stop SMTPSVC service [Display Name: Simple Mail Transfer Protocol (SMTP)]

2. Stop IISADMIN service [Display name: IIS Admin Service]

3. Edit "C:\Windows\System32\inetsrv\MetaBase.xml"

4. Find: <IIsSmtpServer Location ="/LM/SmtpSvc/1"

5. Add (Settings are alphabetical): RelayIpList=""

6. Save file

7. Start IISAdmin Service

8. Start SMTPSVC service

 

發現依然會異常，後來從下列討論串

Server 2022 SMTP Server issue - Server Fault

回文建議多加入

• AccessSSLFlags="0"
• AuthFlags="AuthAnonymous"
• IPSecurity="18000080200000807800008080000080010000008800000000000000000000000400000003000000020000000200000002000000e00000009c000080020000000100000002000000f000000090000080020000000200000002000000fe00000094000080020000000200000004000000000000008800008000000000000000000000000000000000ffffffff7f000001fffff000fffffe00c2f67600ffffe000d4190000"
• RelayForAuth="4294967295"
• SaslLogonDomain=""
• SmtpInboundCommandSupportOptions="7697601"

結果成功了

結論：

要用IIS SMTP作為Mail Relay跳板，建議降版用Windows Server 2019吧！
