sendmail: Introduction and Configuration
HOWTOs
A guide for those of you configuring your first e-mail server.
With the growth of the Internet, e-mail has quickly become the main
vehicle to spread information through the public at large. As the
demand for fast, cheap and reliable e-mail grows, more individuals are
turning to Linux to provide a fast, cheap and reliable solution.
By Eric Seneca on Thu, 2001-11-29 02:00.
sendmail was originally developed by Eric Allman, in 1979, as
"delevermail", which first shipped with BSD 4.0. This program was not
very flexible and required configuration at compile time. With the
growth of TCP protocol and other factors, it became obvious that
delevermail was not flexible enough to handle these new demands.
Eric Allman had to recreate sendmail from scratch, and what he
produced has become the standard for MTAs. Rather than reject
messages that were did not conform to protocols, sendmail is designed
to be tolerant of these messages. For those individuals who have
never configured an e-mail server, this article will demonstrate how to
configure sendmail 8.11.2 after a fresh install of Red Hat Linux 7.1.
By default, sendmail 8.11 is installed during the Red Hat Linux 7.1
installation. As Red Hat has progressed over the years, the installation
process has become very easy. Though this article will not go into
installation details, further documentation is provided on the Red Hat
CD set.
For your new e-mail server to work, you must first get all the DNS
issues straight. First, add the hostname and IP address for the new email server to your DNS server and confirm the address with
nslookup:
[root@testmail /root]# nslookup -sil testmail.blank.com
Server:
192.168.100.1
Address:
192.168.100.1#53
Name:
testmail.blank.com
Address: 192.168.100.134
It is also important that your administrator put a reverse DNS entry to
prevent delays in mail delivery. Most modern e-mail servers use
reverse lookup as a means of authentication for mail transfer. Again,
confirm this setting is correct using the nslookup command on your IP
address.
[root@testmail /root]# nslookup -sil 192.168.100.134
Server:
192.168.100.1
Address:
192.168.100.1#53
134.100.168.192.in-addr.arpa
name = TESTMAIL.blank.com.
As you can see, the DNS entries are setup and working correctly, so
let's move on to actually configuring sendmail. By default, sendmail
installations on Red Hat will only allow SMTP traffic on the localhost.
The output of netstat -nl will show you all ports that have a dæmon
listening; note the line that says 127.0.0.1:25. This means the server
is only listening on the loop back interface for connections on port 25
(SMTP).

This will keep your mail dæmon from accepting e-mail from any
computer except the localhost. To fix this issue, we must tell sendmail
to listen for connections on the external interface. In the case of our
new server, there is only one Ethernet card, with eth0 being the
external interface. To confirm the IP on eth0, simply perform an
ifconfig. Depending on your configuration, this IP can be different
than the address defined by your DNS server, but in our example the
addresses are the same.
[root@testmail /root]# ifconfig
eth0
Link encap:Ethernet HWaddr 00:60:97:DE:E9:99
inet addr:192.168.100.134 Bcast:192.168.100.255
Mask:255.255.255.0

RX packets:6 errors:0 dropped:0 overruns:0 frame:0
TX packets:6 errors:0 dropped:0 overruns:0 carrier:0
collisions:0 txqueuelen:0
This machine has an address of 192.168.100.134 on the eth0
interface. Once you have that address, edit the /etc/sendmail.cf file
and configure the sendmail dæmon to listen on the address.
# SMTP daemon options
O DaemonPortOptions=Port=smtp,Addr=127.0.0.1, Name=MTA
change to
O DaemonPortOptions=Port=smtp,Addr=192.168.100.134, Name=MTA
Once you have completed this task, save this file and restart the
sendmail dæmon using the rc script /etc/init.d/sendmail.
[root@testmail /root]# /etc/init.d/sendmail restart
Shutting down sendmail:
Starting sendmail:
[root@testmail /root]#
[
[
OK
OK
]
]
Now check to see if there has been a change with the netstat -nl
command. As you can see the output clearly shows that a dæmon
(sendmail) is listening on port 25 of the IP address 192.168.100.134
that is assigned to our interface eth0.
[root@testmail /root]# netstat -nl

[root@testmail /root]#
Now that we have sendmail accepting external connections, we need
to assign the domains that can be accepted. This can be accomplished
with the /etc/mail/local-host-names file. Simply put the domain name,
blank.com, in the file.
# local-host-names - include all aliases for your machine here.
blank.com
Once this information is saved in this file, restart the sendmail dæmon
with the rc script sendmail found in /etc/init.d/sendmail restart.
sendmail can accept e-mail for multiple domains on the same server.
Insert the domain name into this file each time you want to add a new
domain.
You now have a fully working e-mail server from the localhost. It can
accept e-mail from anywhere in the world, but can only send e-mail or
relay e-mail from the localhost. Another default security feature is that
sendmail will not allow the relay of any mail to prevent spam
originating from your server. If your users log directly into the server,
this configuration does not need modification. But if your organization
is like most, clients are using e-mail from remote sites. If your users
use clients like KMail or Outlook Express, you will need to allow those
machines to relay e-mail using your new server, but you do not want
to open your site up to complete relay. This can be done by adding the
following line to the /etc/mail/access file and running the command
make access.db after saving that file.
blank.com
RELAY
# Check the /usr/share/doc/sendmail-8.11.2/README.cf file for a
description
# of the format of this file. (search for access_db in that file)
# The /usr/share/doc/sendmail-8.11.2/README.cf is part of the
sendmail-doc
# package.
#
# by default we allow relaying from localhost...
localhost.localdomain
RELAY
localhost
RELAY
127.0.0.1
RELAY
blank.com
RELAY
[root@testmail mail]# make access.db
[root@testmail mail]#
The make access.db command will include your new setting in the
hash database used by sendmail to determine who can relay e-mail off
your server. This will allow connections from inside the blank.com
domain to relay e-mail from your new mail server, and prevent use of
the service to nonmembers. One can also put a subnet of IPs, such as
192.168, to limit inside a domain. Keep in mind that if this setting is to
open, spammers can bounce huge amounts of e-mail off your system.
Now that you can accept e-mail from anywhere in the world, have
configured your domain, and allowed relay e-mail for approved clients,
you may want to allow remote access to that mail. This can be
accomplished with IMAP or POP. With a default server install, not all
required packages are installed to make POP/IMAP mail work. These
services can be obtained by the installation of the imap-2000-9 rpm
package. To check the install status of this package use the following
command: rpm -aq | grep -i imap. If no package is found, insert
Disk 2 of the Red Hat 7.1 installation disk set into your cd-rom and
mount that media. To accomplish this use the mount /dev/cdrom
/mnt/cdrom command.
[root@testmail mail]# mount /dev/cdrom /mnt/cdrom
mount: block device /dev/cdrom is write-protected, mounting read-only
(Successful Mount of Read-Only Media)
Once mounted you can install the package with rpm -Uvh
/mnt/cdrom/RedHat/RPMS/imap-2000-9.i386.rpm.
[root@testmail mail]# rpm -Uvh
/mnt/cdrom/RedHat/RPMS/imap-2000-9.i386.rpm
Preparing...
###########################################
[100%]
1:imap
###########################################
[100%]
As you can see, when I run the rpm search, rpm -aq | grep -i
imap the IMAP package is displayed with output.
[root@testmail mail]# rpm -aq | grep -i imap
imap-2000-9
[root@testmail mail]#
With the correct package install, you now need to enable POP3
connections to your new e-mail server. This can be accomplished in
the /etc/xinetd.d directory by modifying the ipop3 file. Set the value
for disable to no, and save the file. Remember to maintain the case as
it appears in the file.
# default: off
# description: The POP3 service allows remote users to access their mail
\
#
using an POP3 client such as Netscape Communicator, mutt,
\
#
or fetchmail.
service pop3
{
socket_type
= stream
wait
= no
user
= root
server
= /usr/sbin/ipop3d
log_on_success
+= USERID
log_on_failure
+= USERID
disable
= no
}
Now you need to restart the xinetd dæmon to make the new setting
work. This is possible by using the rc script /etc/init.d/xinetd. Simply
issue the restart command as seen below.
[root@testmail xinetd.d]# /etc/init.d/xinetd restart
Stopping xinetd:
Starting xinetd:
[root@testmail xinetd.d]#
[
[
OK
OK
]
]
Now send a test e-mail to your new server and connect to the server
via your favorite pop client. You should now be able to access your email via POP protocol.
One final consideration about your new server is performance. You
may receive complaints about slow connection to your POP server if
the client traffic is being initiated from behind a firewall. The reason for
this delay is that your e-mail server initiates a IDENT session with the
client to confirm the identity of the client. If there is no response to
that query, the server will invoke a timeout value set by default to 5
seconds. This value can be reduced to 1 second to remove most of the
delay caused by IDENT. To change this value edit the /etc/sendmail.cf
file, and reduce the timeout value to the desired value.
# timeouts (many of these)
#O Timeout.ident=5s
change to
O Timeout.ident=1s
Your e-mail server is now working and providing service to your users.
There are many more configurations for sendmail that are beyond the
scope of this article. Linux will provide a very stable, robust platform
for your e-mail needs. To find more information about sendmail visit

Relaying help needed

I have a fully working sendmail set up going, I can send mail using a web client
(Squirrelmail) and receive mail fine using a POP3 server and IMAP. I cannot send
mail from home using a client like Outlook, I get "RELAY DENIED" error, but I can

I've tried auth settings on the client side, but nothing seems to work when I send
mail to a domain not listed in my relay-domains list. Obviously I can't add all
domains or *.com etc, as that will open the relay. Any
ideas/comments/suggestions?!
I need to get this working, without using the ISP's SMTP server for sending, I've got

use the chkconfig command for xinetd specific services. After you install the imap
package, run chkconfig --list. This will list all rc startup services. Under xinetd you
will see the xinetd specific services. ipop2, ipop3, imap, imaps, etc should all say 'no'
under startup. Do a 'chkconfig ipop3 on' will turn on ipop3 for all runlevels. Using
chkconfig accomplishes the same thing as editing the /etc/xinetd.d/ipop3 but is a
cleaner way, and works for all startup rc scripts.

Eric,
Many thanks. I was fumbling around trying to install Sendmail and had almost given
up. I was contemplating giving Qmail a try.
Your article had me up and running in an hour.
Thanks again for a short, easy to follow article.

POP3 DOESN'T WORK: BEST CONFIGURATION ARTICLE YET: IMPORTANT
QUE
Submitted by Anonymous on Mon, 2002-06-03 01:00.
I am new to linux, and the whole open source thing. I found your article really easy
to understand and followed the steps and it worked great except for the pop3
account. I seem to not be able to connect from any client to get mail off the server
remotely. Please help. I can send mail out fine, send mail to the addresses, no
problem. The xinetd.d/ipop3 says that disabled = no
tahnks

make sure you restart the daemon once that setting has been changed.

This is definitly a great article. The explanations are almost idiot proof. Wish the
docs/books out there on Linux/Unix were as good as this.
Thanks a lot Eric.

This article is a life saver... I had searched every books about sendmail in the largest
bookstore in canada.. but couldn't find information on how to do a simple
configuration on sendmail.. It may sound unfair but the sendmail books are not
much help on newbies like me... T
thank you ERIC... how about writing a book on sendmail...

Thanks Eric for this article. I spent weeks trying to get my email server to work
adding the ip address did it. I can't believe no one else has this in their books or
articles it would have saved me a lot of time. I almost didn't read this article because
I read so many before and nothing worked.

You all seemed to have problems with the configuration before you read this article.
So did I, and decided to try out qmail.
I love it. It's really easy to configure, and it's absolutetly the most advanced and
configurable MTA I've ever used. If you have some spare time, I suggest you give it
a try.
qmail
A great guide to qmail

Absolutely AWESOME article... I'd spent most of the day foraging through the web,
the RH docs and it was just that darn daemon-port-options!
Thanks a million!
