Thanks a lot about your quickly replay.
So, for the firstone question i think you are very right thanks..
But day by day i have case with this
"Another question in report is :
RCPT
Helo command rejected: Host not found (total: 7766)
5978 domain1.com
1389 mx.domain.net"
Its a specific domain to reject (in example domain1.com) and this total Number day by day increase.
My zimbra reject this domains? Why? Because havent DNS PRT Records or SPF Records?
And about the lastone question i think its ok
top 50 Senders by message count
-------------------------------
79
user1@mydomain.com
Because about the message count it means Transaction and if someone send an email to 3 people 6 transaction generated.
I think it ok then.
thanks a lot again..
