Boltforms未提交联系表格

I've tried submitting a Bolt contact form using the default one in config.yml but still can't receive mail despite the form succeeding. I'm using my server mail address to send.

Here is my mailoptions in config.yml

mailoptions:
    transport: smtp
    spool: false
    host: {website}.com
    port: 465
    username: contact@{website}.com
    password: password
    encryption: ssl
    auth_mode: login
    senderMail: contact@{website}.com
    senderName: {owner}

My Contact form using boltforms is

contact:
    notification:
        enabled: true
        subject: RE School Assignment
        from_name: {name}
        from_email: contact@{email}.com
        to_name: {name} 
        to_email: {email}
    fields:
        name:
            type: text
            options: 
                constraints: [ NotBlank ]
        email:
            type: email
            options: 
                constraints: [ NotBlank, Email ]
        comment:
            type: text
            options:
                label: Leave an anonymous comment
        submit:
            type: submit
