In addition to Eric Wieling's and Tor Iver Wilhelmsen's plausible suggestions:

Your LAN manager may just have installed MIMEsweeper or some similar virus
checking software to scan incoming mail attachments and is disabling all ways of
bypassing these checks.

Your LAN manager may be worried about Trojan horses phoning home by contacting
phoney POP3 servers.

Why don't you ask him/her?
