Postfix as SMTP, Dovecot as POP: not entirely working...

[Hawkeye0203]

Hello everyone!

I hope someone here can help me.

Here's the situation. I've got a server at home that I run my personal websites on and am transitioning it to my business website server (Fedora 10). I want to be able to run my own email off of it. So far, I can connect to it with an email client (Thunderbird) and download new messages if there are any. I can telnet into it and send an email in this fashion:

[root@server1 /]# telnet localhost 25
Trying 127.0.0.1...
Connected to localhost.
Escape character is '^]'.
220 server1.mydomain.com ESMTP Postfix
ehlo localhost
250-server1.mydomain.com
250-PIPELINING
250-SIZE 10240000
250-VRFY
250-ETRN
250-STARTTLS
250-AUTH LOGIN PLAIN
250-AUTH=LOGIN PLAIN
250-ENHANCEDSTATUSCODES

250 DSN

250 2.1.0 Ok
rcpt to:myaccount@localhost
250 2.1.5 Ok

TEST TEST TEST
.
250 2.0.0 Ok: queued as DA2462654C
quit
221 2.0.0 Bye
Connection closed by foreign host.

but if I change the "rcpt to" address to my domain name ("myaccount@mydomain.com") it looks as if everything is fine, I just never get the message.

Also, when I try to send from my gmail account, I get this:

Technical details of permanent failure:
Google tried to deliver your message, but it was rejected by the recipient domain. We recommend contacting the other email provider for further information about the cause of this error. The error that the other server returned was: 554 554 5.7.1 <myaccount@mydomain.com>: Relay access denied (state 14).

So, in short... I can connect just fine and download emails if they're there, but I can not send emails to an account @ my domain name from internally or externally. Oh, and I have the firewall in my router pointed accurately and the firewall in my server turned OFF.

I hope this makes sense and someone can help me. If I need to post any configs, please ask and I'll do them as soon as possible.

Thank you!

I gather that your 'domain' is registered in DNS externally and pointing to your firewall.
You will also have to have an external MX record for your domain that points to your firewall.
And your firewall will need to let port 25 in through to your mail server.

Having said that, just about every isp blocks port 25 from passing through their internal network.
So you will have to connect via another port (likely 26) and also provide authentication to do so. Many isps let that happen, but not all.

I should have cleared it up. I do have an MX record created that points to mail.domain.com, and mail.domain.com points to the server. I do have a firewall setup on the server itself, but it does have port 25 open. I work at the ISP so I know that it is not being blocked.
