The problem is that I am unable to find any hard limit of acceptance of mails to these destinations. I have even tried creating slow transports for them, but they still seem to drop connections after DATA command or RCPT command.
"lost connection with mx.rediffmail.rediff.akadns.net[119.252.147.10] while sending DATA command)" This happens suddenly after some mails get delivered, and after it happens, most of the mails in my active queue get transferred to deferred queue. This increases the backlog of mails.
