ISA Server Alert: POP Buffer Overflow

Hi,

I'm currently developing an email client that connects to POP3 server (MS
Exchange) via an ISA server.

I am experiencing POP Buffer Overflow problems. The POP mailbox I am
connecting too contains several hundred messages and I am attemping to
send "LIST x" where x is the message number i.e. in a loop from 1 to
total_number_of_messages.

The error ALWAYS occurs after my client has sent 4096 bytes i.e. this is
the TOTAL number of bytes sent after the socket has connected.

I am _not_ overflowing a buffer - at least not intentionally.

Any ideas?

Paul
