Topic: Unknown (Chinese?) error when sending email

- iRedMail version (check /etc/iredmail-release): 0.9.8
- Deployed with iRedMail Easy or the downloadable installer?: No
- Linux/BSD distribution name and version: CentOS 7.5
- Store mail accounts in which backend (LDAP/MySQL/PGSQL): MariaDB/MySQL
- Web server (Apache or Nginx): Nginx
- Manage mail accounts with iRedAdmin-Pro?: Yes
- [IMPORTANT] Related original log or error message is required if you're experiencing an issue.

When trying to send an email a user is getting the attached error. It looks to me like the error given by the iRedMail server is in Chinese. (I'm not an expert in Asian languages, so I apologise if I have the language wrong.) The user does not read or write an Asian language and neither do I, so given the server is configured to use English I don't understand why the server would be giving out non-English error messages. I've never seen this before on my server, or any other.

A search for the error code implies it *might* because caused by an intermediary, like a firewall or ant-virus program. However, it still seems odd that the error is in an Asian language, so if nothing else a translation by someone would be useful. Thanks.

Re: Unknown (Chinese?) error when sending email

It looks like a CJK word, but not.

As a Chinese user, i have experience that if your system or application doesn't have correct locale (character set) (e.g. en_US.UTF-8, zh_CN.UTF-8), the system or program may return some unknown characters or words.

I have no idea why this Outlook got this error. it might be something wrong with the Outlook itself due to can not handle the returned error message correctly, or the error message returned by upstream is messed.


Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?
