If you are trying to fetch the body part and don't know what to fetch,
here is a function that will return all the body parts as a single string with each part separated by '|' character.
Followed by a fuction which will retrieve the structure of that part.
You can then parse the return string by explode() and call imap_fetchbody() on each of the parts.
Chunks of this code was stolen from the following site:

#Function Gets all the subparts , but does not get part: ''
function GetParts($this_part, $part_no) {
//If it is type message(2)=msg envelope,
//Not sure about this assumption : the if statement
//double check with RFC822 on this one.
if($this_part->type==2){
//and there is only 1 subpart of the envelope
//and that subpart is multipart
//otherwise will generate excessive '.1' and
//send wrong part_no to imap_fetchbody
if($this_part->parts[0]->type==1){
$this_part=$this_part->parts[0];
}
}
if (count($this_part->parts)>0) {
for ($i = 0; $i < count($this_part->parts); $i++) {
if ($part_no != "") {
$newpartno = $part_no . '.' . ($i +1);
}
else $newpartno = $i+1;
$partstringary[$i] =
