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?
