<p>There are some numbers in computing, which are boundries, and can cause problems (sort of like that whole y2k issue).</p>
<p>Near 30,000 is the number 32,768, which is 2**15. Now, you'd think to yourself, but wouldn't there be problems at 2**16, which is a nice round number in computer terms?</p>
<p>Well, no, because for an integer of (x) bits, if it's signed, it ranges from (-1*(2**(x-1)-1) to 2**(x-1). So, for a 16 bit number, it goes from -32767 to 32768. If the module in question uses XS (compiled C code), it's possible that it was compiled with a 16 bit signed number in there, which will have problems if you try to deal with numbers greater than 32,768.</p>
<p>If the number is exactly 30,000 or less, this probably isn't the issue. If it's over 32,768, this could be a problem.</p>
<p>From looking at the docs for [cpan://Mail::Box], however, it looks to be pure perl, so I don't think this is the issue in this case.</p>
