Hi

After some digging, the problem is this 600 seconds timeout that in my
case is unsuffisant to transfer one big mail. So retry and ..; same
result.. and again and again

I have verify with strace that data is exchange continuously during the
sync between the two host but i can't succed in uploading the file
during that time.

Is there a way to configure this timeout ?

Eventually a manual sync with a  larger timeout  to restore replication
before limiting maximum size in postfix ?

Possibly a feature would be to have a shorter timeout but applied to the
transmission  ( ie. nothing receive during 30 sec = timeout )
or a timeout compuited base on size ( ie. 300 sec for 10 mo for example)

Any help appreciated
