sendmail problems

Hello,

I’ve tried to send mail with mailx. And I was not successful. I have a
connection to Internet, I can send or receive mail messages with Voyager
mail (POP3). But now I need to use SMTP. Sendmail daemon is running but
mailx can’t send my mails and puts them all to dead.letter. I think the main
problem is in sendmail.cf file. Also I didn’t find aliases.db file in /etc
directory. Can somebody help me to solve this problem?
I use TCP/IP runtime 4.25, QNX 4.25
netstat -a detects smtp listening on port 25

Thanks,

Kamil

If you thought sendmail would work for you without having to hack
the configuration file you’re probably better off getting a simpler
MTA. One question: why do you want sendmail, you say you need to use
SMTP, but for what? One suggestion: www.emyr.net/Sam/mail.html has
a description of how to set up a complete mail system for QNX4,
including an MTA that is possible to set up easily, unlike sendmail.

To use mailx in this way, you also need /usr/ucb/rmail, which comes
packed as /usr/ucb/rmail.something. Rename that or link it to rmail.
You may also have to modify the DD macro in /etc/sendmail.cf -

We have several QNX4 servers in the factory. Each one is a server for an
important application. Me and my colleagues have to check the state of
application every morning. We’ve thought that automatic email system in the
case of some bugs or errors is good for us. So we’ve been trying to use a
QNX system utility mailx for it. In the factory there is only SMTP server.

Thanks, it works. But new problems appeared.
When I send message - it is delivered, but it hasn’t an informations about
sender (from), so I can’t reply.
Where are the sent messages saved(if they are)?

Well, the smtp server I gave you a link to might help if you want to set on
up. Also, SMTP is also a trivial protocol, and if there is a server on the
network, you can connect to it using tcp and mail notifications very easily.

It appears that when you do something like
echo “hello” | mailx -s “Testing” someone@somewhere.com
then the “From” is a composit of the fifth field in /etc/passwd,
the user loginame, such as “root” and the entry in /etc/hosts for
the sending machine.

I haven’t found any documentation on this - it’s mere deduction.
