Update: Parliament IT Now Investigating Mail Gateway Failure
A delivery failure occurred when sending correspondence to committee.reception@parliament.wa.gov.au. The Parliament mail gateway rejected the message due to a TLS certificate SubjectMismatch error, where the server presented a certificate for mail.protection.outlook.com instead of a certificate matching parliament.wa.gov.au. This prevented external mail servers from establishing a secure connection.
Key diagnostic lines included:
- “450 4.4.317 Cannot establish session with remote server… SubjectMismatch.”
- “550 5.4.317 Message expired, cannot connect to remote server.”
A formal escalation note was sent to receptionservices@parliament.wa.gov.au. Reception Services acknowledged the issue and forwarded it to the Parliament IT Team for investigation.
A follow‑up update was sent to Minister Buti and the CCC, confirming that Parliament IT is now examining the certificate fault. The original correspondence will be resent once Parliament confirms that the gateway is functioning normally.
Status:
– Parliament IT investigation: Active
– External mail to Parliament: Still failing
– Next step: Await IT confirmation and resend correspondence.

更新：州议会资讯科技团队正在调查邮件网关故障
向 committee.reception@parliament.wa.gov.au 发送文件时出现投递失败。 州议会的邮件网关因 TLS 证书主题不匹配（SubjectMismatch）错误 拒绝外部邮件。 服务器提供的证书为 mail.protection.outlook.com，而非与 parliament.wa.gov.au 匹配的证书，导致外部邮件服务器无法建立安全连接。
关键诊断信息包括：
- “450 4.4.317 无法与远程服务器建立会话……SubjectMismatch。”
- “550 5.4.317 邮件过期，无法连接远程服务器。”
我已向 receptionservices@parliament.wa.gov.au 发出正式升级通知。 接待服务部门已确认问题，并将其转交给 州议会资讯科技团队 进行调查。
随后，我向 Buti 部长 和 CCC 发出了更新通知，确认州议会资讯科技团队已开始调查证书故障。 一旦州议会确认邮件网关恢复正常，我将立即重新发送相关文件。
当前状态：
– 州议会资讯科技调查：进行中
– 外部邮件至州议会：仍然失败
– 下一步：等待资讯科技团队确认并重新发送文件。

Kemaskini: Pasukan IT Parlimen Kini Menyiasat Kegagalan Gerbang E‑mel
Penghantaran e‑mel kepada committee.reception@parliament.wa.gov.au telah gagal. Gerbang e‑mel Parlimen menolak mesej tersebut kerana ralat TLS SubjectMismatch, di mana pelayan menunjukkan sijil mail.protection.outlook.com dan bukannya sijil yang sepadan dengan parliament.wa.gov.au. Ini menyebabkan pelayan e‑mel luar tidak dapat mewujudkan sambungan selamat.
Maklumat diagnostik utama termasuk:
- “450 4.4.317 Tidak dapat mewujudkan sesi dengan pelayan jauh… SubjectMismatch.”
- “550 5.4.317 Mesej tamat tempoh, tidak dapat menyambung ke pelayan jauh.”
Saya telah menghantar nota eskalasi rasmi kepada receptionservices@parliament.wa.gov.au. Bahagian Reception Services telah mengesahkan isu tersebut dan menyerahkannya kepada Pasukan IT Parlimen untuk siasatan.
Saya juga telah menghantar kemaskini kepada Menteri Buti dan CCC, mengesahkan bahawa Pasukan IT Parlimen kini sedang menyiasat masalah sijil tersebut. Dokumen asal akan dihantar semula sebaik sahaja Parlimen mengesahkan bahawa gerbang e‑mel telah berfungsi semula.
Status:
– Siasatan IT Parlimen: Aktif
– E‑mel luar ke Parlimen: Masih gagal
– Langkah seterusnya: Tunggu pengesahan IT dan hantar semula dokumen.

**REQUEST TO PARLIAMENT – COMPLAINT C/45628**
ReplyDelete**To:** committee.reception@parliament.wa.gov.au
**CC:** receptionservices@parliament.wa.gov.au
**Date:** 11 February 2026
Dear Committee Reception,
I write to request the proper exercise of statutory duties in relation to matters raised under **Complaint C/45628**. My correspondence contains evidence and procedural material relevant to the functions of the Parliament of Western Australia and its committees.
However, my attempts to send the correspondence to **committee.reception@parliament.wa.gov.au** have failed due to a technical fault on the Parliament mail gateway. The diagnostic reports show a **TLS certificate SubjectMismatch error**, where the server presents a certificate for *mail.protection.outlook.com* instead of a certificate matching *parliament.wa.gov.au*. This prevents external mail servers from establishing a secure connection.
Key diagnostic lines include:
– “450 4.4.317 Cannot establish session with remote server… SubjectMismatch.”
– “550 5.4.317 Message expired, cannot connect to remote server.”
All authentication checks on my side (SPF, DKIM, DMARC) passed. The failure occurs during the TLS handshake on the Parliament server.
I respectfully request that this matter be brought to the attention of the **Parliament IT Team** so that the certificate configuration can be corrected. Once the gateway is functioning normally, I will resend the full correspondence immediately.
Thank you for your assistance.
Kind regards,
**Nicholas N. Chin**

ESCALATION NOTE TO PARLIAMENT RECEPTION SERVICES
ReplyDeleteTo: receptionservices@parliament.wa.gov.au
Date: 11 February 2026
Dear Reception Services,
Thank you for your assistance. I am writing to report a persistent technical fault affecting the Parliament email system. External mail to Parliament addresses — including committee.reception@parliament.wa.gov.au — is being rejected due to a TLS certificate SubjectMismatch error on the Parliament mail gateway.
My sending server attempted delivery multiple times, but the Parliament server presented a certificate whose subject does not match the expected domain. As a result, the secure SMTP session could not be established and the message expired.
Relevant diagnostic lines include:
– “450 4.4.317 Cannot establish session with remote server… SubjectMismatch.”
– “550 5.4.317 Message expired, cannot connect to remote server.”
This indicates that the Parliament mail server is presenting a certificate for mail.protection.outlook.com instead of a certificate matching parliament.wa.gov.au, causing external servers to reject the connection under standard SMTP TLS validation rules.
All authentication checks on my side (SPF, DKIM, DMARC) passed. The failure occurs during the TLS handshake on the Parliament server.
I respectfully request that this matter be escalated to the Parliament IT Team for urgent correction of the certificate configuration. Once resolved, I will resend the correspondence immediately.
Kind regards,
Nicholas N. Chin
