I have a problem with email. We have installed wordpress on our server but it does not appear to be sending out any emails. I have configured it for both sendmail and also later when that didn't appear to be working, for smtp. That doesn't appear to be working either. Nothing registers on the server and nothing appears in wordpress's email log page, so I have no idea if it's email is working or not. Does anybody have any idea on what might be causing this behavior and how to fix it?
