Problem with mailx

[Carme Torca]

Hi,

I have configured sendmail to send mails, but when I do:

echo "test correo7"| mailx -s "test correo7" dir1@pep.com

the mail.log shows this error:

Sep 30 10:25:07 server1 sendmail[9802]: gethostbyaddr(192.10.10.10) failed: 1
Sep 30 10:25:08 server1 sendmail[9802]: KAA09802: from=root, size=166, class=0, pri=30166, nrcpts=1, msgid=<200509300825.KAA09802@server1.>, relay=root@localhost
Sep 30 10:25:08 server1 sendmail[9804]: KAA09802: to=dir1@pep.com, ctladdr=root (0/3), delay=00:00:01, xdelay=00:00:00, mailer=relay, relay=pepw [198.10.10.8], stat=Service unavailable

This server 192.10.10.10, has 2 interfaces, and its has to go out from 198.10.10.10, but the log show that it go out with this other interface.
Does anyone could help me??

Hi Carme,

You use the DS (smart relay host) parameter in the sendmail.cf

something like

DSyour_mail.$m

Can you verify that your_mail is in DNS or in the /etc/hosts file with the correct ip.

# nslookup your_mail

Most likely that 192.10.10.10 is not in /etc/hosts or in DNS (which it shouldn't be in DNS anyways unless you have a
local, isolated DNS server) or you don't have /etc/resolv.conf configured correctly on your server.

Hi,

Yes in sendmail.cf

DS pepw

and in /etc/hosts

pepw 198.10.10.8

but I don't know who goes to 192.10.10.10

[Robert-Jan Goossens]

could you post a

# nslookup pepw
# nslookup 198.10.10.8

[Carme Torca]

Here you are,

# nslookup pepw
Using /etc/hosts on: server1

looking up FILES
Name: pepw
Address: 198.10.10.8

# nslookup 198.10.10.8
Using /etc/hosts on: server1

looking up FILES
Name: pepw
Address: 198.10.10.8

[Robert-Jan Goossens]

just looking at your command you used.

echo "test correo7"| mailx -s "test correo7" dir1@pep.com

shouldn't you send this mail to pepw ? or is pep an alias for pepw

[Carme Torca]

The name of the mail' server is pepw, but the domain is pep.com

Hi,

In sendmail.cf the syntax is

DSpepw (without a blanc)

restart sendmail after the modification

/sbin/init.d/sendmail stop
/sbin/init.d/sendmail start

[Carme Torca]

Hi,

I have put DSpepw, at it doesn't works ok.

[Luk Vandenbussche]

Hi,

Does your mail server accept mails from this host. Have you checked the security on your mail server?

[Carme Torca]

Thanks every one,
finally the mail server had not got configured ok, and the server1 has no problems.
Thanks!!
