SQL storage reindex #794

Issue Analysis
After migrating the IMAP backend from SQLite to PostgreSQL, the inbox appears empty even though the message files still exist. This is typically caused by the IMAP index/metadata being out of sync with the actual mail storage.

Solution
Identify your IMAP server and run the appropriate reindex/rebuild commands:

• Dovecot – Delete index files (forces rebuild):

systemctl stop dovecot
cd /path/to/maildir
find . -type f -name 'dovecot.index*' -delete
systemctl start dovecot
