Dear folks, My server running ubuntu server 10.04 with postfix dovecot(IMAP,IMAPs) PAM-LDAP(opends).
My company user want to check and send mail from their own thunderbird in their own laptop, at this time my server only provide checking and sending locally,,,they must login to the webmail when they are from outside of company. They can checking email from outside but they can not sending .. the error is relay access denied !
My question is how to confiugre the mail server for authenticated user can send and receive both from inside and outside via email client software like Thunderbird/Evolution.
Thanks in advanced!
