<p>I'm not sure if this helps, but the following is on Penn's SFS website: "We can accept these attachment types only: .pdf .tif .doc .docx. .txt .jpg .rtf .xls .xlsx</p>
<p>We cannot accept compressed or zipped files. Please note that emailing documents may compromise their security." </p>
<p>So if you sent a file not in the guidelines, or if it was compressed/zipped, it may have bounced back automatically. Good luck!</p>
<p>Thanks! It was a pdf file so I'm not sure what happened, but they said to either fax it or try splitting up the file, for anyone in the same boat.</p>
<p>No. Fax is better. Also UPenn prefer fax (at least last year).
When you send documents via email your private info may stay in the internet provider servers.</p>
