Hi all!

I've been searching high-and-low for this info, but I haven't quite gotten a
handle on this....

I have an RS/6000 system running AIX, and it's on the same network as my
Win98 system which is running a mail-server program called Mdaemon.

All the outgoing mail from our PC's (Outlook Express) gets sent to this PC
running mdaemon, and it goes out onto the internet from there (DSL)

What I need to do is figure out how to tell aix to send outgoing mail to
this same PC when using the unix 'mail' command.

I've been looking through the sendmail.cf file, and I can honestly say I'm a
bit confused.

Does anyone know how to set up sendmail to send all SMTP outgoing mail to a
particular machine at a particular address? I know it's got to be one of
these paramaters :)

I don't use aix for any other mail functions, but I just need a way to send
email messages indicating certain events that occur in aix (when I detect a
new file has been uploaded into a certain dir, etc.)

Thanks much!

-Greg

If you don't want to edit the sendmail.cf file (I still don't know how to do so)
and are running DNS, you can get an entry into DNS for this PC as " mailhost ".
Sendmail defaults to looking for a system called mailhost to send mail to. If
you are not running DNS, then you will need someone who is more knowledgable
about sendmail than I to help you resolve this.

Thanks for the reply!

Dang....I'm not using DNS...I guess I will sit-tight and see if anyone else
can lend a hand...

Thanks again!

Hi,

Consider the DS tag in sendmail.cf

example: DSyourpc.yourdomain

HTH,

what you need is the DS-entry
------------- snippet /etc/sendmail.cf
# "Smart" relay host (may be null)
# Relay host to forward outgoing mail not in the local domain to.
# To forward ALL mail to this relay host, uncomment the appropriate
# rule in ruleset 0, as indicated by the ruleset's comments.
#DSmailer:relayhostname
DSsmtp_pax
---------------------
in this example, all NON-local mail (eg. user on this host) are
forwarded to smtp_pax

dont't forget to put an entry with your "mailhost <--> ipadr" in
/etc/hosts
and to force sendmail to reread the "sendmail.cf"
man sendmail.cf
..
Making the sendmail Daemon Reread the Configuration Information

After you have made changes to the sendmail.cf file, instruct the
daemon to
reread the file. If you started the sendmail command using the
startsrc command,
enter the command:
refresh -s sendmail

Or, if you started the sendmail daemon using the /usr/sbin/sendmail
command,
enter the command:
kill -1 `cat /etc/sendmail.pid`

Both of these commands cause the daemon to reread the /etc/sendmail.cf
file, the
/etc/aliases file, and the /etc/sendmail.nl file.

1)-If you don't use DNS, you have to create /etc/netsvc.conf file and put into it :
hosts=local

this because sendmail search for dns.

2)-You must edit sendmail.cf and search for DS(uppercase!) option end put:
DSsmtp:name_of_your_mail_server(in hosts) or
DSsmtp:[IPaddr of your mail server]

restart sendmail

What you can do is place an entry for your pc in /etc/hosts
eg:
dot.ted.ip.address mailhost

This way you tell sendmail not to directly deliver mail to your
mailserver "mailhost".
If you only use this in script files there should be no problem.

by **sp2 admi** » Sat, 25 Aug 2001 22:15:59

update this line in /etc/sendmail.cf:
#DSmailer:relayhostname

take out the '#', replace the word mailer with 'smtp' or other mailer,
and replace relayhostname with your pc hostname.

WOW! You guys are great!

I'm indeed getting somewhere now...
By following your advice and adding the DCsmtp:mailhost line in the
sendmail.cf I am now able to send mail to INTERNAL addresses, but I'm still
not able to send to mail outside our network...
Here's the setup:

--Internal mail server on a PC (SYSTEM 1)
--AIX system (SYSTEM 2) hooked to same network as SYSTEM 1

Mail server SYSTEM 1 sends & receives mail to/from our internal addresses

We are also able to send email from our PC to other addresses out in the

passes the mail along if it isn't for "myco.com"

From AIX on SYSTEM 2 I can now (thanks to you guys!) send mail to the

internet, it never arrives and generates this error message back:

--- The transcript of the session follows ---
... while talking to mailhost:

It appears that instead of the mailserver passing the outgoing mail on to
the internet, it's deciding that since the user isn't set up in-house, it
will just reject it.

Does anyone know how I'm able to send email out through the mail server from
my PC (and it gets directed to the internet fine), but when I send it from
AIX using the "mail" command it goes to the mail server fine, but then
somehow comes in in such a way as to cause it to be rejected for not being
an in-house email address...?

WHEW! Ok, hopefully I wasn't too confusing (or being to simple) with all my
ramblings.... :)

Thanks much everyone!

Set the value, I believe it's DR, in the sendmail.cf file to the PC's
address. It should have a comment about stmp smart relay. Uncomment and
add the value. Refresh -s sendmail. Test and wait for results. This
depends on the value that you have set for polling. Normally 15-30 minutes
as default.

Hi all!

OK, here's an update:

I can send to in-house (cbsd.com) email addresses, but when I attempt to
send to outside email addresses, aix generates this response (I am sending

220 cbsd.com ESMTP MDaemon 4.0.0; Tue, 28 Aug 2001 10:08:23 -0500

Quote:>>> EHLO cbsd.com

250-cbsd.com Hello cbsd.com, pleased to meet you
250-ETRN
250-AUTH LOGIN CRAM-MD5
250-8BITMIME
250 SIZE 0
mailhost config error: mail loops back to me (MX problem?)

Quote:>>> QUIT

The aix machine is on the cbsd.com domain, as is the mail server. I read in
a FAQ about the MX setting in the sendmail.cf file for this exact error, but
it was a bit vague. I added this line and it still didn't work:
# fallback MX host
O FallbackMXhost=cbsd.com

In the FAQ the example had 2 domains in-house, but in my case I only have 1.

I had to use this line in order to get the domain of the aix machine to show
up as cbsd.com:
Djcbsd.com

Without it the mail server would think I was from an outside domain and
wouldn't let me send any mail at all.

Does anyone have any idea how to get aix to allow these outbound emails to
be sent out of the PC mailserver correctly without this MX error?

Maybe someone can suggest a program other than sendmail that I can use
(pine?) that will be easier to get going...?

Thanks again!

Hi,

You have set the DS entry to "PCmaiserver.dbsd.com" ? not "dbsd.com" !
It should be the same entry as the DR entry.

Try to set the DM entry in the sendmail.cf file. This entry should be
set to your mail server or to your mail domain dbsd.com. By setting this
entry you set the E-Mail address of the sender and to this adress any
error messages will be send. So if you set the DM entry to xxx.yyy then

messages will be send. Someone may correct me if i'm wrong.

Do you get any messages in /var/spool/mqueue/syslog? Or does your
PCmailserver log any messages ?

If you don't need to receive messages on the AIX box you don't need to
have sendmail running as a daemon. I think not having sendmail running
as a daemon is much more secure, especially if you have no firewall.

I don't know whether this solves your problem, but i think it may help
finding a solution.

Hiya!

Thanks for the reply!

So I can kill the "sendmail" process and still use the "mail" command? Does
it invoke sendmail each time?

I do indeed have DS and DR set to "smtp:mailhost" (mailhost is in my etc
file as the PC mail server IP) so the mail is getting there OK.

I tried various DM settings, and I still get the "mailhost config error:
mail loops back to me (MX problem?)" error.

The FAQ mentions this error, but it doesn't really explain the fix very
well.
I've tried adding various domain names in the MX file of the mail server,
but no go.
I'm not even sure if the PC mailserver has any effect at all on the MX
handling, because it's not the DNS....our isp is the DNS.

The only way I've gotten it to work is to change the domain in the
sendmail.cf file to something other than our actual domain...like
"mail.cbsd.com". This will get rid of the MX loopback error, but then it
won't let the mail go out to addresses in the real world because the
security settings of the PC only let mail go out from OUR cbsd.com IP.
To fix this I had to turn off a security feature in the PC to allow mail to
be sent from ANY domain. Not a good security idea, but it seems that there
really isn't a clear-cut fix for this MX error I'm getting.

Thanks again for the reply!
