1. Make sure you can send mail normally using mailserver.

  2. Install one-click deployment and click One-click.

  3. Enter your webmail domain name

  4. Log into WebMail with your email account.

    if we do like this it will create another subdomain, cont we do or follow the standards like how other are doing plesk , panel etc

    The newly installed webmail already supports the function of changing the password

    If you don't want to renew webmail, you can modify the configuration

    config/config.inc.php

    $config['plugins'] = array('attachment_reminder', 'autologon', 'emoticons', 'password');
$config['password_driver'] = 'sql';
$config['password_db_dsn'] = 'sqlite:////www/vmail/postfixadmin.db';
$config['password_query'] = "UPDATE mailbox SET password=%p WHERE username=%u";

    Replace the already installed sql.php with the new installation package sql.php

    Add at the end of the configuration /www/wwwroot/yourwebsite/.user.ini
    :/www/vmail/

    Modify postfix database file permissions

    chown vmail.www /www/vmail
chmod 770 /www/vmail
chown vmail.www /www/vmail/postfixadmin.db
chmod 660 /www/vmail/postfixadmin.db

        My aapanel 6.5.4 not found Roundcube Webmail, please advice

          How do I reinstall, will it have an impact on the website on the VPS, because I already used the aapanel version before 6.5.4

          This seems to be because the network is unstable and the downloaded file is blank. If you try again a few times, you can send me the panel login information and I will check it for you.

              After password change , i cant not login anymore with new password or old password
