The problem does not reproduce. 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--fiqs8s echo@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:
