Description

When the number of email in postfix queue is above "some thousands", the queue management page reports a php memory allocation failure.
I propose to limit the maximum number of email handled per request to 1000.
If the total number is higher, remaining email can be handled after dealing with the first 1000.

I'd change /usr/share/nethesis//NethServer/Module/Mail/Queue.php

-        $process = $this->getPlatform()->exec('/usr/bin/sudo /usr/sbin/postqueue -p | /usr/libexec/nethserver/mailq2json');
+        $process = $this->getPlatform()->exec('/usr/bin/sudo /usr/sbin/postqueue -p | head -n 4000 | /usr/libexec/nethserver/mailq2json');

Every mail needs 4 lines, -n 4000 means 1000 emails.

In testing:
nethserver-mail-common-1.5.4-1.1.gfeb508d.ns6.noarch.rpm

Test case.
1. fill the queue

service postfix stop
for i in $(seq 1 5000); do mail -stest filippo@example.org </root/anaconda-ks.cfg ; done

2. access the queue management interface: php error
3. update and access queue management again

Note: during update postfix will be restarted and will try to deliver email
Remember to empty queue after test.
