Hi
I found in logs:
Jun 23 10:08:54 mx4 postfix/master[4540]: warning:
master_wakeup_timer_event: service qmgr(public/qmgr): Resource

Your operating system kernel is running out of resources. You need
a better computer.
Why better computer ? This is PowerEdge R630 256 RAM and 55 x 2.40GHz
with load ~0,86

But I don't know what this problem is caused by
master.cf
...
qmgr unix n - n 300 1 qmgr
...
I found in net to change:
...
qmgr fifo n - n 1 1 qmgr
But I don't know if it makes sense
That just made the problem 300 times worse.
My bad I mean:
qmgr fifo n - n 300 1 qmgr
