Local EAI address works for local mail but not SMTP mail
 
|
I'm using postfix 3.5.8 on FreeBSD 12.2, the packaged version
I have set up a Chinese EAI domain with some Chinese addresses. The domain is in virtual_alias_domains, and I have an address map: # virtual addresses 回声@xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8s echo #@xn--zbs01c.xn--5nqx41au4nqohsp3axcg.xn--fiqs8s echo 回声@声.电子邮件测试.中国 echo #@声.电子邮件测试.中国 echo (The echo user sends back a copy of the message, for debugging.) 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?

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 to the same > address from outside via SMTP, it says it's not in the table. Any suggestions? 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: $ 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:<whatever@声.电子邮件测试.中国> rcpt to:<[hidden email]--fiqs8s> data whatever . quit Test with netcat: # nc -w 5 127.0.0.1 25 </tmp/echo.smtp 220 wzv.porcupine.org ESMTP Postfix 250-wzv.porcupine.org 250-PIPELINING 250-SIZE 10240000 250-VRFY 250-ETRN 250-STARTTLS 250-XCLIENT NAME ADDR PROTO HELO REVERSE_NAME PORT LOGIN DESTADDR DESTPORT 250-ENHANCEDSTATUSCODES 250-8BITMIME 250-DSN 250-SMTPUTF8 250 CHUNKING 250 2.1.0 Ok 250 2.1.5 Ok 250 2.1.5 Ok 550 5.1.1 <whatever@声.电子邮件测试.中国>: Recipient address rejected: User unknown in virtual alias table 550 5.1.1 <[hidden email]--fiqs8s>: Recipient address rejected: User unknown in virtual alias table 354 End data with <CR><LF>.<CR><LF> 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...
