.Junk/cur

[tsimtung]

Hi,
Some of my email users said that incoming emails dropped into .Junk folder abnormally, they even haven't enabled any anti-spam, but go to this .Junk folder.
Is this .Junk folder the default directadmin dovecot email folder? or it it caused by thirty-part program (like outlook)?
How to avoid it go to .Junk folder?

Thanks,

Stanley

Hello Stanley,

According to Dovecot settings from DirectAdmin, the Junk folder is a special folder for SPAM:

    mailbox Junk {
        special_use = \Junk # autocreate Junk, but don't autosubscribe
        auto = create
    }

Adult filter, and other filters including SpamAssassin/rSpamd can be enabled by default. So you might check in DirectAdmin what exactly is enabled.

For sure third-party programs (like outlook) can have an impact as well.

ok, thanks for your reply.

(I have already checked that no spam settings or filters for this domain in our da server side, it is most likely caused ty third-party.)

Read mail logs for possible clues. If emails are moved to a Junk folder by software installed on a directadmin server, then traces can be found in mail logs on the server. Names and locations of mail logs will differ depending on what kind of OS you use: CentOS like or Debian/Ubuntu. For CentOS/CloudLinux/AlmaLinux it will be /var/log/maillog and /var/log/exim/mainlog, check the link for location of other logs:

If logs do not have traces, and you have enough old logs, then it's a third-party mail client installed on their network device or Sieve filters (that can be reviewed and edited in RoundCube).
