My ISP closed 25 and 110 ports and dont want to open them, but he said, that i can use his POP3 and SMPT....
Is there posibility in postfix to configure to use my ISP pop3 and smpt server to recieve emails?
To use your ISP's SMTP server as a relay, use the relayhost directive in /etc/postfix/main.cf Example:
relayhost = smtp.myisp.com
Be advised that your ISP may require some form of authentication before you are allowed to use their smtp server to relay outgoing mail. If that is the case, you will need to figure out what they are using, then configure postfix to match it.
