mail problem with ... Unbalanced '<'

Hi, sorry if this is slightly off topic but I thought someone might have some idea of the problem. I am using the mail function like so; mail( $to, $subject, $this->mime ); where the arguments have the following values; print '$to = '.$to."\n"; print '$subject = '.$subject."\n; print '$this->mime = '.$this->mime."\n"; $to = "Tom Hodder" <mlm@globalgold.co.uk> $subject = htrheht $this->mime = This is a MIME encoded message. --=_ab31b28377a78eb2ae3ca4c36b9262ec Content-Type: text/plain Content-Transfer-Encoding: base64 RW50ZXIgeW91ciBQTEFJTiBURVhUIG5ld3NsZXR0ZXIgaGVyZS5FbnRlciB5b3VyIFBMQUlOIFRF WFQgbmV3c2xldHRlciBoZXJlLkVudGVyIHlvdXIgUExBSU4gVEVYVCBuZXdzbGV0dGVyIGhlcmUu RW50ZXIgeW91ciBQTEFJTiBURVhUIG5ld3NsZXR0ZXIgaGVyZS5FbnRlciB5b3VyIFBMQUlOIFRF WFQgbmV3c2xldHRlciBoZXJlLkVudGVyIHlvdXIgUExBSU4gVEVYVCBuZXdzbGV0dGVyIGhlcmUu DQoNCg0KDQpFbnRlciB5b3VyIFBMQUlOIFRFWFQgbmV3c2xldHRlciBoZXJlLkVudGVyIHlvdXIg UExBSU4gVEVYVCBuZXdzbGV0dGVyIGhlcmUuRW50ZXIgeW91ciBQTEFJTiBURVhUIG5ld3NsZXR0 ZXIgaGVyZS5FbnRlciB5b3VyIFBMQUlOIFRFWFQgbmV3c2xldHRlciBoZXJlLkVudGVyIHlvdXIg UExBSU4gVEVYVCBuZXdzbGV0dGVyIGhlcmUuDQoNCg0KRW50ZXIgeW91ciBQTEFJTiBURVhUIG5l d3NsZXR0ZXIgaGVyZS5FbnRlciB5b3VyIFBMQUlOIFRFWFQgbmV3c2xldHRlciBoZXJlLkVudGVy IHlvdXIgUExBSU4gVEVYVCBuZXdzbGV0dGVyIGhlcmUuRW50ZXIgeW91ciBQTEFJTiBURVhUIG5l d3NsZXR0ZXIgaGVyZS4= --=_ab31b28377a78eb2ae3ca4c36b9262ec-- this generates a return email with the following contents...............
