Hi
I'm very new to linux so would be greatful if someone could help me resolve this Postfix problem.
I'm trying to configure Postfix to just send externally (not receive). I'm able to send the messages to postfix however they are stuck in the deferred mail queue.
When checking with pfqueue, the status of each mail is either "No route to host" or "Connection timed out"
I've not included a relay host as was trying to send direct, however when I input a relay host, the problem is still the same as being "No route to host" or "Connection timed out".
I have spoken with my ISP who told me they don't block any ports at all.
