email and sendmail help

[mcater]

Hi,
I want to send emails from my hpux 11.00 server to certain users.
So email would go from hp server, to companies windows email server, to users.
What settings do i need to make in the hp server to be able to send emails?

sendmail has to run to send mails initially.

# ps -ef | grep sendmail
root 1026 1 0 Sep 20 ? 0:51 sendmail: accepting connections on port 25

Try as,

# echo "hi" | mailx -s "test" root@localhost
# mail

It will give recent mail to you.

To other machines you have to have reachablity to that machine.

# echo "hi" | mailx -s "test" root@machine1.domainname.com

It will work. You can as well as use sendmail instead of mailx command.

hth.

One way is to set the DS entry in /etc/mail/sendmail.cf

Then stop and start sendmail to pick up the change.

Your server need to be in primary domain and sendmail should be configured properly.

# /sbin/init.d/sendmail start

# ps -ef|grep sendmail
check to confirm daemon now appears

# mailq

to check mail queue
# sendmail -v
test settings.

thanks to everyone, didnt realise how easy it was - i thought there would be more to it.

It is working, however i get this following message each time i use mailx:
Switch map aliases: unknown member map aliases.dns: Socket operation on non-socket

any ideas how to fix/stop it?

Look at the docs here,

It can get more complicated if you want. If you want to send outside your network you might need to allow relaying for your HPUX host on your exchange (windows mail) server.

As for that message I can't say I've seen it before, looks like a dns problem perhaps? I will add more as and when I find out.

Here is a post I picked up from a search, it might have your answer:

I feel the problem is with /etc/mail/sendmail.cf configuration file.

Set:
O QueueDirectory=/var/spool/mqueue

Try to restart it as,

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

hth.

This post seems to cover the steps to configure sendmail quite comprehensively. I like SEP's answer.

I think I would be tempted to look at my /etc/hosts (to add the exchange server IP and full name).
Then see what /etc/nsswitch.conf (putting the hosts entry to look at files first) and then see what resolv.conf looked like.

[mcater]

O QueueDirectory=/var/spool/mqueue

is already in sendmail.cf

[Gavin Clarke]

Here are examples of /etc/resolv.conf and /etc/nsswitch.conf that work for us:

/etc/nsswitch.conf

#
# /etc/nsswitch.files:
#
# @(#)B.11.11_LR
#
# An example file that could be copied over to /etc/nsswitch.conf; it
# does not use any name services.
#
passwd: files
group: files
hosts: files [NOTFOUND=continue] dns
services: files
networks: files
protocols: files
rpc: files
publickey: files
netgroup: files
automount: files
aliases: files

/etc/resolv.conf
domain ????.com
nameserver IPofDNSserver
nameserver IPofDNSserver

I suspect that it is the /etc/aliases file that may contain your problem. Although this is only a guess.

[Muthukumar_5]

what is there in /etc/mail/service.switch for aliases.

I hope it will be like,

aliases dns files or bind

remove except files and put it as,

aliases files

# Restart sendmail with this.

hth.

[mcater]

the /etc/mail/service.switch
has:
#hosts dns files
aliases files

i commented out the hosts and restarted sendmail but still get same error.
the /etc/aliases appears as default.

i have checked resolv.conf and nsswitch.conf and all appears ok.

we use dns here.
