Incorrect sieve path for Dovecot 2.4 on Debian 13 (trixie) and Ubuntu 26.04 (resolute)

The configuration for personal sieve rules in Dovecot 2.4 is incorrect on Debian 13 (trixie) and Ubuntu 26.04 (resolute), causing Dovecot fail to load main sieve script. Please follow the steps below to fix the issue.

• Open the file /etc/dovecot/dovecot.conf and locate the sieve_script personal block, which should look like this:

sieve_script personal {
    type = personal
    driver = file
    path = ~/sieve/dovecot.sieve
    active_path = ~/sieve/dovecot.sieve
}

• Replace path = ~/sieve/dovecot.sieve by path = ~/sieve and save the changes:

sieve_script personal {
    type = personal
    driver = file
    path = ~/sieve
    active_path = ~/sieve/dovecot.sieve
}

• Restart dovecot service:

systemctl restart dovecot
