sendmail configuration

mwagiru — Mon, 05 Mar 2007 03:20:09 GMT

I have configured sendmail to send mail to internal users in our LAN via MS Exchange but I cant get it to send mail outside like to xyz@gmail.com.

Why does my sendmail try to resolve?
I can send all emails to internal LAN, but I cant send to external email like gmail.See my partial attached output.

Your /etc/nsswitch.conf file determines how your system will attempt to resolve host names.

Your /etc/nsswitch.conf file specifies the DNS server(s) you want to use to resolve host names.

This specific tells you that the server cannot get to any of the DNS servers specified in your /etc/resolv.conf file.

Your /etc/nsswitch.conf file specifies the DNS server(s) you want to use to resolve host names.

That should be, "Your /etc/resolv.conf file specifies the DNS server(s) you want to use to resolve host names.

Sorry for any confusion.

Re: sendmail configuration

mwagiru — Wed, 07 Mar 2007 04:22:19 GMT

I have configured my /etc/mail/sendmail.cf with a smtp server
DS172.31.100.69

Why can't sendmail send to xyz@yahoo.com ?
My /etc/rc.config.d/mailservs has
export SENDMAIL_SERVER=1
export SENDMAIL_SERVER_NAME=""

help!

Re: sendmail configuration

Keith Johnson — Wed, 07 Mar 2007 08:26:53 GMT

It looks as if you are not able to query your DNS server.

Check your /etc/nsswitch.conf and /etc/resolv.conf files to ensure they are configured correctly for how you want to do name resolution.

1. If you are using DNS for resolution, your /etc/nsswitch.conf file should have an entry like:

hosts: dns [NOTFOUND=continue TRYAGAIN=continue] files

And, your resolv.conf file should list the DNS servers for your site and should look like:

domain your.domain
nameserver
(Note that you can list up to 3 nameservers.

2. If you are using /etc/hosts as your only name resolution, make the hosts line in the /etc/nsswitch.conf file read:

hosts: files [NOTFOUND=continue]

Also in this scenario, if you have an /etc/resolv.conf file, move it elsewhere.

Once these are configured properly try an nslookup on the address to which you want to send mail.

Shalom,

Hi, whats the OS? Sendmail on HP-UX doesn't do that(the smclient part).

I believe based on reading the entire thread and a sickening level of experience with sendmail that you have done everything right.

The relay server referred to in the DS directive is mishandling the mail. That server has a problem not the one you are working with.

Re: sendmail configuration

mwagiru — Wed, 07 Mar 2007 10:25:10 GMT

The relay server is an MS Exchange server.
And yes, the OS is HP-UX 11.11i

Apparently, when I send mail to internal recipient it arrives but still shows a great deal of :
;; Querying server (# 1) address = 172.29.200.99
;; Querying server (# 2) address = 172.29.200.134

;; Querying server (# 1) address = 172.29.200.99
;; Querying server (# 2) address = 172.29.200.134
;; Querying server (# 3) address = 172.29.200.11
;; res_query: send error

;; res_query(172.31.100.69., 1, 15)
;; Querying server (# 1) address = 172.29.200.99
;; Querying server (# 2) address = 172.29.200.134
;; Querying server (# 3) address = 172.29.200.11
;; Querying server (# 1) address = 172.29.200.99

;; Querying server (# 2) address = 172.29.200.134

Check the following link for information regarding the "Starting sm-client [FAILED]" error you're receiving, it may help.

http://www.sendmail.org/~ca/email/doc8.12/SECURITY

For your other error, mail not leaving your server, I still think it might be DNS related based on these error messages:

;; Querying server (# 1) address = 172.29.200.99
;; rcode = 3, ancount=0
NO: errno=0, h_errno=1
getcanonname(yahoo.com), trying files
text_getcanonname(yahoo.com)
getcanonname(yahoo.com), failed, status=68
yahoo.com: Name server timeout

So please try this command and let us know the result:

nslookup yahoo.com

Re: sendmail configuration

mwagiru — Thu, 08 Mar 2007 00:43:46 GMT

Why does my sendmail attempt to resolve?
I want it to send all request to my relay server (Exchange Server) which is connected to the internet.

My Sun server has sendmail and it sends all requests to the Exchange Server which will take it from there.

Huh?????

Re: sendmail configuration

Sameer_Nirmal — Thu, 08 Mar 2007 03:02:23 GMT

You need to ask MS Exchange server administrator to add the host in the relay list. This will allow this host to send email outside world's domain.

Regarding sm-client error, you need to take a look at the error messages in /var/adm/syslog/mail.log

Unless otherwise required as mail server, you don't need to run sendmail as server.

Re: sendmail configuration

mwagiru — Thu, 08 Mar 2007 03:16:28 GMT

Finally....
I found the culprit....I just commented out this line:

# pass to name server to make hostname canonical
#R$* < @ $* $~P > $* $: $1 < @ $[ $2 $3 $] > $4

Thanks guys for your help!!!
