I need help. I’m trying to reproduce an issue, but I keep hitting so many errors that I’m completely stuck. I'm reproducing this on a single machine.

1. Setting up the environment:

groupadd -g 500 vmail && useradd -M -u 500 -g vmail -s /bin/false vmail && mkdir -p /tmp/mail && chown vmail:vmail /tmp/mail

2. Starting up Dovecot.
3. User mailboxes don’t exist yet.
4. Saving an email via CLI:

doveadm save -u user1 -m INBOX /tmp/1.eml

5. Checking the email UID, but it’s missing:

curl -u "user1:hello" -k imap://localhost:143/INBOX -X "UID SEARCH ALL"

• SEARCH

..

mail_home = /tmp/mail/%{user}

Don't save mails to /tmp. With systemd Dovecot gets a unique /tmp directory when running as a service. So doveadm sees a different /tmp than the running dovecot.
