My server is sending all emails via exim smarthost to other specialised exim server (both cPanel). How may I limit customers from sending out SPAM ? Mean to scan outgoing emails and delete/store in some folder which ones identified as SPAM. Preferrably the scan part to be on exim email proxy cause it is much idle.

May I able to block outgoing mail server on any account.
I have root access and Cpanel Installed.
We've got a dedicated server at our company that hosts several sites and email accounts. Today I noticed that in the mail queue (from Plesk) we have like 5 or 6 messages from the same customer with around 400 destination addresses for EACH one. This would be like 2000-3000 emails to be sent. It isn't spam as it's some kind of newsletter.
I don't really know how the QMail server handles this, but it's been 5 hours since some of those messages entered the queue, and they are still there, so it seems that is having some difficulty.
I don't pretend to limit the amount of emails an user can send per minute or per hour, but I would like to know if there is any way of managing the queue like, lets say, send 50 message per minute. As far as I know, the mail queue right now (by default) starts sending the messages as they come, which means it could send 1000 in a few seconds if it can handle it.
I don't even know if this would be better or worse, meaning that maybe messages could get queued when the server could handle them, so some customers would see that emails are not working instantly as they do now. It also would be good if this tool (if exists) could report the current status of the queue, saturation, etc...
We're a bit worried because a couple of days ago we had some kind of attack and our server started sending hundreds of emails with fake sender and the CPU went overloaded and the mail queue was too big.
Where do I setup limits for email sent by PHP scripts?
They do not seem to be throttled by the plan's outgoing limits at all.
How is the Number of outgoing Mails counted by mails or by recipients?
With a limit of 25 mails per hour is it possible to send 25 mails with 200 recipients each before they will be blocked or will one mail with more the 25 recipients exceed the limit?
In the documentation for Plesk 12 there is no information on what is happening if the limit for outgoing mail is reached.
If there is a limit of 50 mails per hour on a mail account and someone is trying to send 60 mails in one hour, what does happen with these 10 mails over limit?
1. Are there send 50 mails and the rest of 10 mails are deleted and will never be sent?
2. Or are these 10 mails sent later?
3. Can there be sent more mails in the next hour or is the mail account now blocked for sending mails?
I upgraded Plesk to 12.0.18 on centos5.8 just because of new feature, Outgoing Mail Limit. There was no problem until I had to increase one of my client's domain limit. I set its Mail Box, Domain & subscription limit to "unlimited", but user get limit exceeded warning again. I search this problem on internet, and the only related article was [URL] .... but I didn't got meaning of "server wide limits".
Where is this feature config file?
