Hi. I have a VPS with Ubuntu LAMP 10.4; Postfix; courier; IMAP I can send and receive emails on it, but when I try to use it w/ Thunderbird or Outlook from my home PC I get: Code: 554 5.7.1 : Relay access denied Also when I try to telnet from my windows PC i get Code: Could not open connection to the host on port 23. Connect failed Whats the proper settings of Postfix to achive this? and what port to use? I guess its 110 for pop3 ?
