Asia Mail Services
Business email hosting for companies trading between China and Brazil. Your own domain, a gateway in Singapore, support in Portuguese, Chinese and English.
Companies trading between China and Brazil tend to run their correspondence on the wrong tools: a Chinese domestic provider with weak reputation abroad, Gmail (blocked in mainland China), or Microsoft 365 degraded by the Great Firewall. Quotations and purchase orders end up in spam folders, and nobody supports both sides in their own language.
Asia Mail Services hosts mailboxes on the customer's own domain and routes all mail through a gateway in Singapore, reachable from both sides, with SPF, DKIM and DMARC configured per domain. Accounts are set up by hand. Bulk and marketing mail are not accepted.

Why companies in this trade need it
What we see when we review a new customer's domain:
| Situation | What goes wrong |
|---|---|
| Chinese exporter on 163.com or QQ | Weak international reputation. The Brazilian importer on Google or Microsoft finds the message in spam days later, or never. |
| Chinese exporter on Gmail | Gmail is blocked in mainland China. |
| Chinese company on Microsoft 365 | Slow and unstable through the Great Firewall; mobile sync silently stops. |
| Brazilian importer on a local provider | Poor deliverability towards Chinese providers; quotations arrive late. |
| Both sides at once | No provider supports them in Portuguese and Chinese at the same time. |
Who runs it

Change log
Changes to the service that a customer would notice, newest first.
- Platform consolidated on a single server in Singapore: the mail gateway and mailbox storage now run together, so message content stays in Asia end to end. Reverse DNS configured; SPF, DKIM and PTR validated by an independent checker. The Hong Kong gateway was decommissioned and its IP address is no longer ours.
- Client connections (IMAP, SMTP submission, webmail) now carry the original client address through the Hong Kong gateway, and brute-force blocking is applied at the gateway itself.
- Inbound filtering scores the real sending server instead of our gateway. Mail that fails filtering is delivered to the Junk folder instead of being bounced, so the platform never sends bounce messages to forged senders.
- Webmail addresses per brand —
webmail.chinatrademail.com,webmail.asiatrademail.com,webmail.jinhemail.com,webmail.yuhuamail.com— each with a valid certificate. - Automatic account setup for Thunderbird and Outlook now returns
store.asiamailservices.comand only the ports the gateway serves. - 2048-bit DKIM keys published for every platform domain; DMARC reports consolidated at
dmarc@asiamailservices.com. - Website rewritten: setup guide, postmaster page and this change log added.
- Sign-in and webmail pages branded; interface language fixed to English, with Portuguese and Chinese available per user.
- First version of this website published, with Terms of Service, Acceptable Use Policy and Privacy Policy.
- Mailbox server and Hong Kong gateway in operation; outbound route validated end to end.
