i have pop emails from mediatemple each configured in the client without any local server
we have virus sending emails with title my photo
i updated the antivirus in all servers and computers

when i monitor the traffic on my firewall i found the spam source is coming from computers in my network; even if i formatted the computer or scan it still the same nothing found no virus there

the POP is configured in port 110 and with SMTP 25 for ourgoing

now if i update the POP 995, SMTP to send using 465 with SSl will that reduce this spams or what?

Your firewall gives you some important information: what computers are sending this spam.
Record whats ip and block on your firewall temporary during cleaning.
Second, go to one infected computer and seach for any kind of malware, I had some cases antivirus installed (McAfee) not detect virus but using another (try with avast per example) detects and removes infection.
If can not detect virus, you will need to format all affected computers, remember set up your local firewall before connecting to LAN because some malware spreads using vulnerabilities to autoinstall. This causes clean computers are infected on same time you connect to network.
To end, unblock all blocked computers on your firewall.
