Dovecot says the message was stored into a Spam mailbox but it's not there

18 Feb 2018

      Hi,

I have a problem with storing messages into a Spam folder by dovecot. 
Log says that message was stored into Spam mailbox but when I check 
there is no message in users's Spam mailbox.

cat /var/log/mail.log | grep sieve | grep Spam :

*Feb 17 05:09:11 mailserver dovecot: lda(user@domain): sieve: 
msgid=<b599df639ffa4d20f6e8d2bcff791286@somedomain.pl>: stored mail into 
mailbox 'Spam'*

Where are these messages if not in the Spam folder where they should 
be?  /var/vmail/domain/user/Maildir/.Spam/cur/
