When you get an abuse report, that means that your service has been used for activities that are not allowed by the law (for example sending mass/spam emails).
In such cases, please find the cause (has it been done by you or your service has been compromised and misused) and take immediate actions to prevent further complaints.
Note:
Please be aware that failing to address the situation, leave us with no other option other than suspending your service(es) after 24 hours.
