Hi, Running old server , and noticed that mail sent form PHPmailer would have old domain name in headers. When i search of an old hostname in /etc forder i get these results (image below) with mentions. Shoul di just replace them manually and restart , or should i change things via admin panel as well ?
What are the hostnames set in: /etc/mailname /etc/hostname /etc/hosts /etc/postfix/main.cf - The "myhostname = " config And which files have the new one and which the old?
