Well, I'm assuming that you have at least ONE typo in your post -- your errors are all in webmail_class_ver2.php, but your post says that we're looking at ver1.
Anyway, assuming that's just a typo, let's take a look at your first error. Undefined variable: arr on line 138. If you look at your function, $arr is never defined before it's used. You jump in the loop if $i < count($msgs) and start appending to the $arr array.
The first iteration of the loop happens when $i is zero... so what happens when $msgs is an empty array? You never add anything to $arr. Thus, $arr is never created, and you get the error on line 138 when you try to return $arr.
Second error, line 111: $arr[$i]["date"] = gmstrftime("%b %d %Y", strtotime($msg->date));
Well, if $msg->date isn't a valid time string, strtotime will complain about it. Nuff said, I guess... You should check to see if that string is nonempty before you pass it to a function that accepts something specific.
Rather than continue figuring out someone else's problem, I suggest the following: It seems to me that you're much better off reporting these problems to the author(s) of the class. They're much more familiar with it and might be actively supporting and maintaining it.
Take care,
Nik
