I will answer this by myself. I found a workarround for this issue with the unreadable/unzoomable mails for the Xperia:

In the file

/usr/share/jolla-email/pages/HtmlViewer.qml

find:

    function setHtml(html) {
    htmlBody = html
    // Respect viewport meta tag if exists
    if (!hasViewportMetaTag(htmlBody)) {
        // This affects only to layouts that do not have width defined in body content.
        // Smaller content layout gets scaled up to WebView's width. Basically meaning that
        // html text emails will get scaled up by factor (1.5*Theme.pixelRatio) rounded to nearest half.
        // With higher scale factor content layouts starts touching edges of WebView and that hinders
        // legibility. Thus, this 1.5 base factor.
        var scale = Math.round((1.5 * Theme.pixelRatio) / .5) * .5
        experimental.customLayoutWidth = webView.width / scale
    } else {
        experimental.customLayoutWidth = webView.width
    }
    // reload html
    webView.loadHtml(htmlBody, "file:///usr/share/jolla-email")
    onScreen = true
}

replace with:

    function setHtml(html) {
    htmlBody = html
    // Respect viewport meta tag if exists
    //if (!hasViewportMetaTag(htmlBody)) {
        // This affects only to layouts that do not have width defined in body content.
        // Smaller content layout gets scaled up to WebView's width. Basically meaning that
        // html text emails will get scaled up by factor (1.5*Theme.pixelRatio) rounded to nearest half.
        // With higher scale factor content layouts starts touching edges of WebView and that hinders
        // legibility. Thus, this 1.5 base factor.
       //var scale = Math.round((1.5 * Theme.pixelRatio) / .5) * .5
       // experimental.customLayoutWidth = webView.width / scale
   // } else {
        experimental.customLayoutWidth = 350
   // }
    // reload html
    webView.loadHtml(htmlBody, "file:///usr/share/jolla-email")
    onScreen = true
}

After this, restart the email app and most mails are readable. It is not a solution, just an ugly fix, which helps me a lot.
