there is a different at debug:ldap
problem user log : debug:ldap with localhost (127.0.0.1) meanwhile normal user using Public IP : auth: Debug: ldap(user-2@domain.co.id,202.146.xxx.xx)

is there anything else we need to check ? we don't make any change
have you got any idea ?

we already check at roundcube / setting/ filter, there is no filter/rule here.
and also check at LDAP user properties

. Thank you .

This doesn't make any sense.

iRedMail-0.9.6 has global sieve rule enabled by default, it will move detected spam to Junk folder. BUT, no way the mail which is already delivered in INBOX will be moved to Junk by sieve rule. It sounds like this user has some other IMAP client accessing same mailbox. Please check with your user.

thank you ..

Yess it's happened
first disable all rule / sieve in to roundcube
- then create move all message to mailbox also not working
- create some rule from roundcube also not working

I'm trying live monitoring from user webmail (roundcube), send an email test, email go to inbox,  then when refreshing email already move to junk folder, checking complete header spam score only 0, xx so its safe.
check everything log and everything normal.

it seems something error with sieve.

Re: 1 user email always goes to junk folder

Sieve rules are applied WHILE delivering new message, it doesn't apply to messages which are already in mailbox. So it doesn't make much sense to me.

Do you have multiple IMAP client (e.g. Outlook, macOS Mail.app) open? i know macOS Mail.app has its own filters, if you do have Mail.app, please try to disable the filters temporarily for testing.

Yess, it also doesn't  make sense to me, but unfortunately this happened (only in 1 user)
( very strange,  mail in the inbox suddenly move to junk folder after 5-10 minutes)

Already checked on user and using pop3, both on mobile and laptop with leave message option.

finally,
copy all Maildir, then delete user account and then create again and rebuild email structure (openldap) then copied old maildir to new maildir

Re: 1 user email always goes to junk folder

Maybe you can enable Dovecot plugin "mail_log" to monitor whether it's moved by an IMAP client:
https://wiki2.dovecot.org/Plugins/MailLog

Also check the IP address.
