Receiving E-Mail Problems, need help, please!
 
I have just configure Redhat Linux 9, my apache webserver works fine, and i have just installed the Squirrelmail and send e-mails without problems. My question is, how can we receive e-mails from others?

Thanks in advance.

do u have a registered domain? if it is so cechk the MX record.

bignitz 07-25-2004 09:26 PM

Yes, I have registered our domain and its MX records. Before, I was using MS Windows 2000 Server for mail using Workgroupmail for Windows as our mail server, and it works fine. I used the same setting for my newly installed Linux box but I failed. I have just installed Firestater for our firewall and internet sharing then made smtp and pop3 ports open for communication.

have u configured sendmail to execpt emails comes from external interface? because by the default sendmail (smtp) listens only loopback interface.

but u dont have to choose sendmail as MTA. u can prefer postfix, qmail and others.
i use qmail. u can install qmail including spam filter and antivirus by reading the great guide at www.qmailrocks.org

I've installed postfix, and send mail using squirrelmail, works fine. But still the receiving is my problem. I'm still new at postfix and don't know how to configure.

Thank you for your replies, it helps me a lot in exploring the power of linux.

Thanks in advance.

Still I couldnt receive email eventhough i've use postfix. Anybody has a solution?

Is Postfix even listening on the IP of your NIC?

What IP does your MX record point to?

Are you sure your allowed SMTP traffic inbound, or maybe just outbound?

Is the machine running Postfix behind a NAT firewall configuration? If so, have you properly forwarded the external IP on port 25 to the internal IP of the Postfix box?

It would probably be easiest if you posted what your domain name is so people can tell from the Internet where the e-mail is getting stuck.

Yes, I've configured our linux box to work as our internet gateway and as our mail server. I try to telnet port 25 of my server and found out that it was open for communication. NAT firewall was configured properly.

How could I test the server on where the e-mail was stuck? Log Files?

Still I can't recieve mails
 
What now should I do? Should I get back to my f*c*king windows box?

maxut 08-09-2004 09:22 AM

it is up to u. u can prefer M$ windowz.

tell me your server ip or FQDN to check smtp connection.

You can test your e-mail by making a dailin connection to the internet en then make a telnet 25 connection to the external ip address of your firewall.
Type helo to force it to give you it's name.

Maybe your provider is caching the mail:

Make a telnet 25 connection to their mail server and type
etrn Your_domain.com

Maxut and I both told you that the fastest way to figure out the problem is to post the domain name so we can check it. It's very hard to determine what the problem is if you don't give a complete description of your setup. "I've configured it to work as our mail server" is completely meaningless, because maybe you only think you set it up correctly but you really missed an important step? There's no way to know for sure unless you post exactly what you did, or you post your domain name so other people can help you.

Also, I'd advise you against posting profanity, even if it is partially obscured. You may wish to review the forum rules.
