Problem sending message with attachment >100kb

[Gregor]

Hi,

I got a service (written in C#) that sends out messages to a third party
system.
The messages contain encoded attachments.

Everything works fine as long as the messages are small (say < 100kb).
When I try to send message >100kb I get an expception stating:
"The underlying connection was closed: the connection was closed
unexpectedly"

Any ideas?

Thank you,

Gregor
