I try to implement postfix on Centos6 for a simple use and for single domain.
I also use Dovecot as POP/IMAP server.
I can telnet the server from a remote machine on port 25 / 110 / 143 and everything is ok.
But the problem is when i try to make connection from a client (outlook or trustedbird), so i can't add any account to the client and the connection refused.
Any idea let me troubleshoot this problem ??
You're in the wrong place. This is the support forum for Postfix Admin, a tool for managing virtual domains/mailboxes using Postfix. You'd be better heading over to postfix.org.
