This line shows the size of the message data, estimated by the client, is
about 570Kbytes.

This line shows the speed of data transfer from the client is very slow
(25320 bytes / 77 seconds = 300B/s, about 2400bps).
It will take about 2000 seconds (more than 30 minutes) to relay the message.

Your log in the former mail also show the slow transmission.

>03/26 14:27:50.73 [1904] 23+0: ## SMTP unbuffering slow DATA (34310B/202s).

So it will be helpful to peep the IP packets from such client host and
observe the status of the TCP connection with tcpdump and netstat or so.

I added the log output in DeleGate/9.6.0-pre8 (which is released this
morning) to record SMTP DATA transfer periodically when it is slow.

Cheers,
Yutaka
