Greetings.
I am running an ME9 server and will be migrating our ISP linux mail onto it shortly.
The problem is there are several hundred accounts that have somewhat weak passwords and possibly infected computers connecting to them. I would need a service, software or other that can keep track of the outgoing traffic from my mail server in an easily managed way where I can take action on offending users. I'm having trouble finding what I'm looking for since I'm unsure of what terms to search for.
Can someone suggest a good solution for this? Maybe there's already something in ME able to do this?
The old linux work horse has a poor MTA currently and I don't wish to continue that reputation.
Thank you.
