Sendmail -- Can not receive mail

fhleung · 11-28-2005, 07:16 PM

I am

start learning how to configure sendmail, I found many posts with similar topic and they are quite helpful. Now I finish half of the settings, I able to send emails but not receive.

I comment out

Code:

#DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

and edit

Code:

dnl define(`SMART_HOST',`mail.myISP.com')

to let my ISP mail server to handle mails.

I am able to send mail by

Code:

echo hello |sendmail -v something@gmail.com

or squirrelmail interface. But I can not receive emails. Do I need to do more edit on the sendmail.mc ?

Please point out the problems. Thank you.

You have to allow relaying for your domain. Do not allow realying for any other domain, because someone could use your server as a relay for spam.

How do I configure NOT allow relay for any other domains? Sorry I am quite new to sendmail config so I don't know much the syntax and features for.

Can anyone know the reasons not receive mail?

Here are a couple decent how to's on setting up Sendmail.

On the first one, setting up realying is about a 10th of the way down.

Instead of commenting this:

Code:

    #DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

Use this:

Code:

    #DAEMON_OPTIONS(`Port=smtp,Addr=0.0.0.0, Name=MTA')dnl

This way you'll have sendmail bound to all interfaces. You probably can't receive mail because sendmail is not listening on the right interface.

Hope this helps.

I have google the problem and read the sendmail FAQ
http://www.sendmail.org/faq/section5.html#5.3.1.3
http://www.sendmail.org/~gshapiro/8....rtOptions.html

First of all I try send mail to myself

Code:

echo hello |sendmail -v  name@mydomain.com

and the mail still in the outgoing queue /var/spool/mqueue

Code:

MDeferred: Connection refused by mydomain.com.
Fs
$_localhost.localdomain [127.0.0.1]
$rESMTP
$swww.mydomain.com
${daemon_flags}
${if_addr}127.0.0.1
S<root@mydomain.com>
MDeferred: Connection refused by mydomain.com.
rRFC822; name@mydomain.com
RPFD:<name@mydomain.com>
H?P?Return-Path: <>
H??Received: from www.mydomain.com (localhost.localdomain [127.0.0.1])
        by www.mydomain.com (8.12.8/8.12.8) with ESMTP id jB17gPNw004491
        for <name@mydomain.com>; Thu, 1 Dec 2005 02:42:26 -0500

        for name@mydomain.com; Thu, 1 Dec 2005 02:42:25 -0500

Anyone know how to read above and see what error going on?
My sendmail.mc DAEMON_OPTIONS like

Code:

dnl define(`SMART_HOST',`mail.myisp.com')

dnl DAEMON_OPTIONS(`Port=smtps, Name=TLSMTA, M=s')dnl
dnl DAEMON_OPTIONS(`port=smtp,Addr=::1, Name=MTA-v6, Family=inet6')dnl
dnl DAEMON_OPTIONS(`Port=submission, Name=MSA, M=Ea')dnl
dnl DAEMON_OPTIONS(`Port=smtp,Addr=127.0.0.1, Name=MTA')dnl

MAILER(smtp)dnl
MAILER(procmail)dnl

Did you set Sendmail to allow relaying for your domain? If I remember right, I had the same problem the first time I setup Sendmail. After I set Sendmail to relay for my domain it worked.

fhleung · 12-02-2005, 11:39 AM

mmm.... I didn't set Sendmail to allow relaying for the domain? How can I edit the config file to do this?
