My Postfix mailserver can't send out mails directly!

I use RedHat9, and postfix mailserver.
Are there any method to make a copy of every outgoing and incoming mails (for particular user)? If there are, is it possible to send this copied mails to another address?

Best regardes

Removing/commenting the "relayhost" line from main.cf should stop postfix from delivering all e-mail via your ISP's MTA.

I have tired this more times. When I remove that line and I restart my mail damon, I get the following message (on the log file)after the first sent message:

Mar 24 13:28:24 ns1 postfix/smtp[9085]: AF049F4AD2: to=<ALENA.RANDALL@cnn.com>, relay=none, delay=185667, status=deferred (connect to nycmail1.turner.com[64.236.170.101]: Connection timed out)

What is this?

I have a machine behind my firewall. I am unable to send out emails from the nat'ed box because mail servers out in the real world see my mails as being spoofed (or whatever the term is). All my emails are tagged with the internal IP of 192.168.1.14 or with its unresolvable internal hostname. The mailservers reject this kind of email as far as I know.

So, are you behind a firewall?

Unfortunatly, I have no fix for this yet. My mentor (google) hasn't yet given me an answer...

One thing to check is, can you receive email from the internet?

hi,

not sure if this might be the problem ...but it could be that ur isp's mail server uses the TLS authentication system .... if that's the case you have to conbfigure postfx to issue the STARTTLS command when it connects to ur isp mail server .... though i am not sure how to do this .

to check if ur isp mail server uses TLS

open shell and type telnet <isp mail server add> 25

see if it gives any message about TLS authentication ... if it does then u know it uses TLS and u need to configure postfic appropriately.
