postfix warning: pipe_command_write: write time limit exceeded

Question

I am trying to recieve a very large email which is being forwaded from exchange server. File size of 80GB. I have increased the file size limit in main.cf

However after an hour I got the following error in the log. How can I resolve this?

My configuration:

main.cf

message_size_limit = 819200000
mailbox_size_limit = 819200000
command_time_limit = 10000000000s
ipc_timeout = 10000000000s
sendercheck_time_limit = 10000000000s

master.cf

smtp      inet  n       -       n       -       -      smtpd
        -o content_filter=filter:dummy

filter    unix  -       n       n       -       -      pipe
          flags=Rq user=nobody null_sender=
          argv=/data/enkive/enkive-1.1-CE/support/filters/postfix/enkive-socket-filter/dist/enkive-socket-filter localhost 2527 ${sender} ${recipient}

I have managed to send 10MB file. I am using postfix to forward emails from exchange to enkive which is a mail archiving tool

Answer 1

Email was never designed to deal with gigabyte-sized messages; consider using something - anything! - more appropriate for large file delivery.

You already received the huge file; this is postfix failing to send it to the pipe(8) transport you configured as its destination.

That said, postconf -d does not show your configuration, so the information displayed is useless.

You should include the relevant lines from master.cf and any main.cf parameters related to this transport.
