sendmail configuration.

[M Yasir Khan_1]

Hello All,

My objective is to send email from my HP-UX Box (10.20) to my mailbox in exchange server, residing on the same network.

first, when i treid to send the mail from my hp-ux box through mailx, it had been giving the error: "unable to qualify my own domain name () -- using short name".

after this error, based on some body's recomendation, i put two entries in /etc/hosts which are,

10.8.1.2 hps.mydomain.com hps hps exs
10.8.1.100 exs.mydomain.com exs

hps: is my HP UX Server and
exs: is my exchange server

now after these changes, when i try to send the mail through mailx, it is not giving any error, no mail return to problem in /var/adm/syslog/mail.log . but no mail in my exchage's mailbox.

i can see files in /var/spool/mqueue.

Please suggest me what to do????

thanks in advance,

Yasir.

Hello Yasir,

Refer to the foll. link for configuring sendmail on your HP-UX 10.20 box.

http://docs.hp.com/cgi-bin/fsearch/framedisplay?top=/hpux/onlinedocs/B2355-90110/B2355-90110_top.html&con=/hpux/onlinedocs/B2355-90110/00/00/47-con.html&toc=/hpux/onlinedocs/B2355-90110/00/00/47-toc.html&searchterms=configuration%7csendmail&queryid=20040103-000709

Check out the chapter "Installing and Administering Sendmail".

Yasir,
I'm sure you probably checked this, but try pinging the exchange server to make sure that the HP-UX server can see it through the host file.

Hi Yasir,

"sendmail" does not use "/etc/hosts" actually, not even if you include it in your "/etc/nsswitch.conf". "sendmail" uses its own config file for that purpose in "/etc/mail/"...

Happy new year,

I would suggest the following diagnostic step to figure out what the problem is:

sendmail -v -d8.99 -d38.99 someone@yourdomain.com

Type a little text

.


You will get diagnostics pointing to one or more of the following causes:

1) networking can not use files first(/etc/nsswitch.conf) see prior post
2) Not using the DS directive in sendmail.cf
3) The Exchange server is not configured to accept relay mail. This should be done by ip address. The 10.20 server must have a fixed ip address
4) Mail relay is being blocked locally in the /etc/mail/access file.

Post up the results of my diagnostic command for further assistance.

For Hazem: In the /etc/hosts, the entry is already there. the HP Box can ping the FQDN of the exchange server.

For Wodisch: in the /etc/mail/sendmail.cw I configured the aliases as suggested.

For SEP:
Okhay, I got the problem. here is some text from that diagnostic command:

getcanonname(mydomainname.com), trying dns
dns_getcanonname(mydomainname.com, trymx=1)
dns_getcanonname: trying mydomainname.com. (ANY)
NO: errno=239, h_errno=2
getcanonname(mydomainname.com), failed, stat=75
me@mydomainname.com... mydomainname.com: Name server timeout
me@mydomainname.com... Transient parse error -- message queued for future delivery

So, now what i must do to resolve this problem???

related to this, i've some more questions:
Is there a way to put MX record in hosts?
How to restart sendmail daemon?

thanks in advance and regards,

Yasir.

Hello All,

Thanks for everybody's help. the problem has been resolved.

I didn't has the DNS server defined for my box. i created the /etc/resolv.conf and put the domain and name servers. and then everythings has started working :) ...

thanks alot and regards,

Yasir.

PS: how can i restart sendmail ?

Restart Sendmail:

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

You might also want to add the DS macro in your /etc/mail/sendmail.cf

# Relay all non-local mail to the "Smart" relay host (DS) via UUCP: #
# make two chnages to this file. First, set macro S (DS) to the name #
DSyourexchangeserver

You may also want to set the DM macro as well:

# who I masquerade as (null for no masquerading) (see also $=M)
DMyourdomain.com
