Have postfix running on Fedora 8 with ISPConfig... able to receive mail, but, not send it out. Can send locally, however. When trying to send externally I get "Connection timed out (port 25)" error in the log. I haven't been able to find much about this error anywhere... any ideas?

Also, when trying to send from Outlook mail client, I get a 554 5.7.1: Relay access denied... when sending from local webmail client, it says it sends fine, but, it gets deferred after a "Connection timed out" error in the log.

main.cf file is setup exactly like the "Perfect Server" setup for Fedora 8 & local-host-names are correct.

thanks!

First you are getting relaying denied because your network is not in "mynetworks" as for outbound email it seems like you cannot make connections outside to port 25. Test that you can connect to mail servers on the internet using this command

Code:

telnet a.mx.mail.yahoo.com 25

No such luck... I am on a godaddy dedicated server... and from what I'm reading, they require a relayhost, which I believe is smtp.secureserver.net, but, this doesn't help, either.

Code:

Trying 209.191.118.103...
telnet: connect to address 209.191.118.103: Connection timed out

Thanks!

Then you need to setup postfix to use that as a smarthost

Code:

relayhost =  smtp.secureserver.net

but just test with telnet as well and see if you can connect to it on port 25 if not then your data center is blocking port 25 speak to them.

some success...

GoDaddy's relay server is k2smtpout.secureserver.net so, I set...

Code:

relayhost = k2smtpout.secureserver.net

am able to connect to this host with telnet then restarted postfix and now it does have some capacity to send, although quite slow, but at least its sending...

but, I am still getting this error... I think it has to do with mynetworks setting:

Code:

NOQUEUE: reject: RCPT from...: 554 5.7.1: Relay access denied.

my local IPs are 10.0.0.1-255 and I have mynetworks set to:

Code:

mynetworks = 127.0.0.0/8, 10.0.0.0/8

If the server is is at godaddys where is the 10.0.0.0/8 network ? Because your server at godaddy will not see your connection as coming from that range as it is not routable and will reject it

Have you tried sending the mail from the server itself ?

the local IPs on my server are 10.0.0.1, 10.0.0.2 and 10.0.0.3 on eth0

My public IPs are received by a hardware firewall then forwarded to the server on the above IPs. I'm not sure if 10.0.0.0/8 is the right configuration or not. If not, any idea what I need to put here?

Mail can be sent directly from the server to external email addresses and also using the webmail app, just not from an external mail client.
