[SOLVED] I can't mail messages locally. Connection is refused

PreguntoYo · 04-28-2018, 06:18 AM

Hello:

I'm using Slackware 64 14.2 stable. I'm trying to send messages locally, like:

Code:

$ mail root
$ mail root@localhost

# mail preguntoyo

But messages are never delivered. I've had a look at /var/log/, and files such as: maillog.1, maillog.2, etc are being created. This is today's maillog:

Code:

Yes, I've noticed that "Connection refused by...", but this is the first time I'm trying to use the mail command and I'm clueless. Since now I had been using Thunderbird for e-mails. I just wanted smartd to send messages to root about SMART status of my HDs, and then noticed the thing wasn't working.

I have a firewall (iptables) set up and I've changed my localhost name to "deathstar". May it be the firewall?.

Thanks for any help in advance.

That means that sendmail is not running.
By default the sendmail startup script is not executable, so you have to run:

Code:

sh /etc/rc.d/rc.sendmail start

If you want sendmail to start on boot make the above script executable:

Code:

chmod +x /etc/rc.d/rc.sendmail

Cheers

I hadn't noticed the /etc/rc.d/rc.sendmail script. It's so easy that it's embarrassing.

Now I have 487 messages ahead for reading...

And, in case you missed it, the default MTA in the next Slackware stable is Postfix. So, rc.postfix instead. Just in case you run into this problem again.
