Resend email feature seems broken (sends raw HTML)

    Hi there,

    I inadvertently left FluentSMTP in disabled mode for over a month.

    There’s around 120 important emails that ended up not sent. I have them all in the logs, and I can view their content perfectly fine in the logs. Yet when I use the “Resend” feature, the email received is all raw HTML.

    E.g.

    <!DOCTYPE html PUBLIC "-//W3C//DTD XHTML 1.0 Transitional//EN" "https://www.w3.org/TR/xhtml1/DTD/xhtml1-transitional.dtd">
<html xmlns="https://www.w3.org/1999/xhtml" xmlns:o="urn:schemas-microsoft-com:office:office" lang="en-US">
<head>

<style type="text/css">
#outlook a {

}

.es-button {
mso-style-priority: 100 !important;
text-decoration: none !important;
}

a[x-apple-data-detectors] {
color: inherit !important;
text-decoration: none !important;
font-size: inherit !important;
font-family: inherit !important;
font-weight: inherit !important;
line-height: inherit !important;
}

.es-desk-hidden {
display: none;
float: left;
overflow: hidden;
width: 0;
max-height: 0;
line-height: 0;
mso-hide: all;
}

[data-ogsb] .es-button.es-button-1 {
padding: 20px 40px !important;
}

@media only screen and (max-width: 600px) {
p, ul li, ol li, a {
line-height: 150% !important
}
...

    That’s just some lines from the start of the received email.

    It’s super important I be able to send these emails out, but obviously I need to resolve why they are not formed correctly.

    Please advise.

    Thanks …. Jonathan

    This issue appears to be server specific.

    It’s not occurring on another site I manage, which is on a different server configuration. It also continues to occur on the site in question even with all other plug-ins disabled, and using just a default WordPress theme.

    So it doesn’t appear to be a plugin conflict, nor a theme / custom theme code issue.

    I can see that the emails (the resent emails) have their content-type set to text/plain. Obviously that should be set to text/html.

    As a temporary workaround/solution, I have added code the forces all emails to have the text/html value in the content-type header.

    E.g.:

    add_filter( 'wp_mail_content_type', 'set_html_mail_content_type' );

function set_html_mail_content_type() {
    return 'text/html';
}

    Ideally this code wouldn’t be required, as it may cause issues if at some stage a text email is intentionally sent. Not likely on this particular site, but as it’s a hack/workaround it would be good to resolve the underlying cause instead.
