Composed mail not showing on certain webmail client(s?)

[Desdinova]

Hi,

I have a webshop that dynamically generates an e-mail message that is being sent to the recipients. It all works pretty well except on 1 webmail client, I can't seem to figure out what's causing this issue. The mail is received, headers are there, but the message is completely empty. When getting mail from that provider through POP3, everything is A-OK. It seems as though there's some kind of filtering going on on the webmail ..

I have all kinds of headers, in the right order they are:

		$this->mailHeaders .= "From: ".$this->mailSenderName." <".$this->mailSenderAddress.">\n";
		$this->mailHeaders .= "MIME-Version: 1.0\n";
		$this->mailHeaders .= "Reply-to: ".$this->mailReplyToName." <".$this->mailReplyToAddress.">\n";
		$this->mailHeaders .= "Content-type: ".$this->mailContentType."; ";
		$this->mailHeaders .= "charset='".$this->mailCharset."';\r\n";

Sometimes CC and BCC follow after this.

I do not use a body tag, I start off with a DIV and use valid HTML. No attachments are embedded, no external images or stylesheets will have to be loaded.

Content is wordwrapped() at 60 chars.

Any help is greatly appreciated. I tried contacting their technical department, but they don't care (it's Orange webmail, providing ADSL and Mobile communication. Their customerservice aches).

Sounds like a bug in the web-mail client.

Only thing I can possibly think of is that the Email is being sent as user "nobody" which is being caught by a spam filter that only runs on the webmail client, or is configured differently. If you view the header do you see something like this?

Return-Path: <[e-mail]>

If so, set Return-Path to be the same as the sender Email

There's a return-path, though it doesn't match the sender Email. I'll try replacing it with the sender address.

I'll give a status report tomorrow 😉
