Unable to reply or forward mails

[iceroyx]

I'm not using apache on my machine, I have a website on a hosting server with apache installed and a couple of mail accounts I made. I've noticed that I cannot reply or forward mails which contain the header fields From, To, Date embedded in the text. When trying to send these mails the following error is displayed in the browser:

Error 406 Not Acceptable

I solved this problem by deleting the header fields each time I need to reply or forward a mail, of course this is not a real solution, I want to know why this happens and what should be done to fix it.

Is it 'cause of MIME types?

Thanks!

I think that is a problem of the webmail interface your hoster is using. Ask your hoster to fix this.
