That is what appears to be happening. The recipient definitely gets the
message (multiple times).

>What is the output from:
>postconf | grep smtp_data_

smtp_data_done_timeout = 600s
smtp_data_init_timeout = 120s
smtp_data_xfer_timeout = 180s

>Is the timeout problem message size dependent?
No, many messages are smaller than 8k in size.

>How many of those messages are you sending in parallel?
One message/recipient.

Thanks,
