Hello,
I can quickly and professionally fix this outbound spam issue as i have been performing similar tasks for several years as system admin. I can configure/limit and place pro-active prevention to prevent spam emailing.
I can also check if your IP addresses are blacklisted, are there any security weaknesses, exploits on server and can harden the server as well (by updating software, patching apache, php etc, checking server permissions, checking exim configs, deploying CSF firewall and monitoring software etc.)
I guarantee there will be no spam issue for the next few years and if somehow you would have the same problem i will solve the issue for free and continue to provide support as long as you want/need.
Kindly check my previously completed projects as well as reviews to qualify my experiences.
Let me know if you have any questions/requests and thank you for your time in advance,
Thank you!
Emre.
