HI, I am running postfix on cents 7. I believe my server has been compromised and I have received many bounce back emails on 1 of my email account. I do not use this server for SMTP. Currently the webmin is too slow, ssh works and Email (POP3) not working as too slow. The freelancer should do the following as a remedy: Fix the issue. Implement security so this should not happen in future. Let me know in a doc file, reason for this and solution applied (so in future, if I happen to change or format the server, I can implement the security myself) KINDLY DO NOT BID ABOVE MY SAID BUDGET FOR THIS PROJECTS, SUCH BIDS WILL BE DELETED.
