Possible to check total incoming/outgoing size per domain?

Question

Hello :),
Is it possible to see the top incoming or outgoing emails by total size?
The intention is to determine which domain or emails may be eating the network bandwidth.
Also, is there a Report to check the Incoming email graph/statistics a listener or specific domain receives? I tried Monitor > Incoming Mail, with the domain options but it does not show them. As we have several clients in the same Appliance we need a Report for the email that only client1.com or client2.com received.
Thank you in advance.

Answer 1

My unoffical answer is using Mail Flow Central in the unoffical way.
login the MFC mysql
select rcpt_domain,sum(message_size) as total_size from recipients r, messages m
where r.sid = m.sid
and r.mid = m.mid
and timestamp > unix_timestamp(date_sub(now(), interval 1 day))
group by rcpt_domain order by total_size desc limit 0,20
This will give the top 20 total message size processed by receipent domains of last 1 day.
This executes just forever if you want more days or add the transfer_id as a condition..(i left it out delibrately).
There are alternatives,
1.
In my experience, your incoming total size statistics can, alternatively, be generated by your ultimate message store server (sendmail/postfix/exchange).
Your outoging total size is a little difficult if not using the above tweaked method.
2.
scp the mail_logs out regularly, look for "MID XXXXXX ready YYYY bytes for "
Do some mining scripts.
