That is, Postfix accepts mail for 回声@声.电子邮件测试.中国 and 回声@xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8s, successfully looks up both virtual aliases, and attempts to deliver both to a local user "echo" (which in my case does not exist). I saved your virtual alias map to file, and replaced 'echo' with 'echo@localhost' so that mail would not leave the test machine. $ cat /etc/postfix/jl-virtual 回声@xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8s echo@localhost #@xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8secho@localhost 回声@声.电子邮件测试.中国 echo@localhost #@声.电子邮件测试.中国 echo@localhost $ postmap /etc/postfix/jl-virtual Verification: $ postmap -s hash:/etc/postfix/jl-virtual 回声@声.电子邮件测试.中国 echo@localhost 回声@xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8s echo@localhost Postfix configuration: $ postconf -x virtual_alias_maps virtual_alias_domains smtputf8_enable smtpd_relay_restrictions smtpd_recipient_restrictions virtual_alias_maps = hash:/etc/postfix/jl-virtual virtual_alias_domains = 声.电子邮件测试.中国 xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8s smtputf8_enable = yes smtpd_relay_restrictions = reject_unauth_destination smtpd_recipient_restrictions = SMTP commands, to show that 'known' aliases are found, and that 'unknown' aliases are properly rejected: $ cat /tmp/echo.smtp ehlo wzv.porcupine.org mail from:<> SMTPUTF8 rcpt to:<回声@声.电子邮件测试.中国> rcpt to:<回声@xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8s> rcpt to: rcpt to: data whatever . quit Test with netcat: # nc -w 5 127.0.0.1 25 : Recipient address rejected: User unknown in virtual alias table 550 5.1.1 : Recipient address rejected: User unknown in virtual alias table 354 End data with . 250 2.0.0 Ok: queued as 4Ddw0z4T2fz4w8j 221 2.0.0 Bye maillog: Feb 14 12:57:07 wzv postfix/smtpd[249245]: connect from localhost[127.0.0.1] Feb 14 12:57:07 wzv postfix/smtpd[249245]: improper command pipelining after EHLO from localhost[127.0.0.1]: ...omitted...

Re: Local EAI address works for local mail but not SMTP mail
Sorry, this is just wrong. DNS supports IDN domains just fine using IDNA2008, and Postfix has good EAI support. I've gotten EAI addresses to work fine with the domain in mydestination, so this appears to have something to do with virtual aliases.

When I send a message locally to the EAI address it works. When I send a message to the same address from outside via SMTP, it says it's not in the table. Any suggestions? make a map that converts eai to idn, then then there is no problem, is it safe to do virtual alias eai to idn ? its not safe to have smtpd eai enabled yet or make postfix have it internaly so both eai and idn is common supported, problem is postfix is basicly ready for eia but no dns servers to support this yet
