I'm trying to edit the body content with transaction.add_body_filter(/text/(plain|html)/, function (ct, enc, buff), it won't work, the received email is empty, and just the subject is ok. Even when I just return the buff again it doesn't work at all.

But when I send the email as plain text, it works. Any idea?

We will need more info. Show us some code and the source of the email in question.

I'm sending email from my office365 account.

exports.hook_data = function (next, connection){
    var plugin = this ;
    connection.relaying = true;
    connection.transaction.parse_body = true;
    connection.transaction.add_body_filter(/text\/(plain|html)/, function (ct, enc, buff)
    {
        var buf = buff.toString('utf-8');
        var pos = buf.indexOf('\<\/body\>');
        buf = [buf.slice(0, pos), '\n Added this paragraph to the existing body.', buf.slice(pos)].join('');
        return new Buffer(buf);

    });
    next();
}

i can confirm got the same problem, when i put anything into connection.transaction.add_body_filter() got empty body even if the filter is not firing the issue become active with recent versions Haraka

I can confirm the same problem - I have an internal plugin that adds a body filter. I have found that PR #2187 that fixed bug #2176 is where the behavior change occurred. The specific commit is https://github.com/haraka/Haraka/commit/dc43bdc36ab54a1137827f942423e8240c70f83c.

I have confirmed that re-adding the following lines seems to fix the issue but am not 100% sure if this is the correct fix.

I will try to get an SMTP conversation capture later tonight for an easier reproduction.

Same here. It happens only for mails with multipart bodies. Works fine for plain text or plain html emails. Is there any plan to fix this?
