NIP 6 results: Port of call
Nym network opens ports for WhatsApp calls, Session Messenger, and SMTP (with protections for operators)
分享
The latest Nym Improvement Proposal (NIP) 6 passed operator governance voting last month, and the results are now live.
As per the proposal, the Nym network has updated its exit policy to permit ports 22021, 3478, 3480, 3484, 587, and 465. Importantly, this allows users to use important third party services like WhatsApp calls, Session Messenger, and messaging via email clients using SMTP ports while having rate limiting for spam protections.
You can see the details of the NIP 6 proposal and stay updated on Nym operator governance on the Nym Forum.
The results of NIP-6
Ports 22021, 3478, 3480, 3484, 587, and 465 are now permitted by the Nym exit policy.
As of 20 January 2026, 90% of NymVPN gateways have updated to the latest software which permits access to the new ports (393 of the 713 total nodes in the network, 427 are configured as gateways).

Rate limiting for SMTP port 465
SMTP port 465 is a TCP port typically used for encrypted email clients such as Thunderbird, Outlook, and some mobile apps.
During the operator governance vote, some operators raised concerns about opening the SMTP port due to the risks of handling potential spam traffic distributed through email clients. To address these concerns, Nym team decided to test and implement a rate limiting measure to better protect operators.
What is Session Messenger?
Session Messenger is a private, decentralized, open source messaging app. It is one of the only messaging apps to offer built in metadata protection, making it a trusted Nym ally in the fight against surveillance. Try it out!

VPN 和混合网络：终于结合了
直到最近，传统的 VPN 还是集中式单跳代理服务。为了掩盖客户端流量，VPN 通过自己的服务器重新路由用户数据，用 VPN 自己的 IP 地址取代用户 IP 地址。问题就在这里：用户流量的元数据日志很可能存储在这些目标服务器上。只要我们的数据被集中起来，就会面临数据泄露、网络攻击和政府监控的风险，所有这些都可能泄露我们的上网历史。
