Hi, we are a small hosting startup and the linux team needs help. For one reason or another we often get hacked and servers start sending SPAM. Limits don't work, email are sent multiple ways... then servers get blacklisted and of course nobody can send email. Everybody get upset.
I am not sure why limits don't work. Do they get removed by the hackers? We use zabbix for monitoring servers. Maybe some ideas what to monitor to get an early heads up before spam is sent over tens of thousands of times. Is spamassassing the best there is? Are there alternatives that we could explore?
What changes could I suggest to make to prevent spam outbreaks?
Thanks.
