Hi,
When I attach large images > 5-10MiB/s, sometimes this occurs, I tried
setting:
tcp_windowsize = 65535
I also tried setting ecn to 0.
But neither seemed to fix the problem below. I can send the same images
to an Exchange server and they send through with no problems. Also, if I
send smaller attachments (1-2MiB) it typically goes through fine.
Thoughts?
