Mailbox INBOX: Mailbox opened because: lib-lda delivery

Hi, postfix+dovecot installed on ubuntu20.04 and both up and running. i can send and receive emails. But emails going to "cur" folder immediately after receiving to inbox (new) folder. The issue i cant receive this emails to my desktop email client. i can send from desktop but receiving only to "cur " folder. After debug i got only this: Mailbox INBOX: Mailbox opened because: lib-lda delivery. So emails automatically placed to cur folder because of they are opened (cur folder is read. inbox is unread). Cant resolve this issue. Any help will be appreciated, thank you.

 

fixed, issue was on email client (Kmail), changed to Thunderbird and got all emails
