Basic Pleskian
Server operating system version
Linux
Plesk version and microupdate number
Version 18.0.45 Update #1
Our VPS server is suspended immidiately by our provider because on Talosintelligence.com/reputation_center the daily mail volume was 2.4.
After it come back I cant find any sign of abuse, i checked the loads / memory / cpu, specific for mail server and didnt see any increase this day. Also traffic or processes not any more then any other day. Beside i checked the outgoing mail statistics, also here is no siggn at all for spam or any customer who was over the limit of 10 messages per hour.

Because the suspention I take this spam very serious, im looking for Plesk professional who can help me investigate this server so this problem will be find and we can make better prevention against this spam.

Thank you for your help.
