mail server error

["Antonio Godinho" <antonio at nambu.uem.mz>]

Hi all,

I have a wireless network connected to my network through a 
Cisco 4700M through an ethernet port. When I send mail from a 
machine running FreeBSD on the wireless network to my network 
everything goes fine but if I try to send an attachment of more than 
80Kbytes the mail does not go through and sendmail gives an I/O 
error. From a server in the wireless network to another one in the 
wireless network there are no problems.
Does anyone have any idea what could be causing this problem? I 
suspect it is something in the cisco but I can not quite figure what.

Cheers,
