[SOLVED] Connection to Linux email server
would really appreciate your help on this concern of ours.
we just finished setting up a new email server at work using red hat, postfix, dovecot.
we were successful in sending and receiving mails but ONLY through webmail using squirellmail (via our company website).
however, if we use other email software application like thunderbird, incredimail, or even ms outlook to access our emails, we can only send emails but the software is denied connection to the server when receiving.
i have checked our firewall (fortigate 310b) to verify whether connection from our DMZ to internal network is allowed and it does.
