postal 🚀 - SMTP stopped working

Can you try stopping Postal and then running setcap from here: https://github.com/atech/postal/wiki/Installation#preparing-your-operating-system

I stopped the Postal using postal stop

After that I ran the line:

sudo setcap 'cap_net_bind_service=+ep' /usr/bin/ruby2.3

Don't know if it did anything, after that postal restart

can you send us the output of netstat -lnp?

Here's the output:
netsat lnp.txt

Github is generating those strikethroughs -_-

Yes, you should include it in backticks or remove the tildes ~

willpower232 on 10 Apr 2018

Your netstat suggests you have several other things than Postal running on this server. In order for Postal to function properly, it must be the only purpose of the server so that it can bind to the system ports for SMTP and web.

willpower232 on 10 Apr 2018

I am not running any other applications on this server, just Postal.

I didn't touch the server since yesterday, when it stopped working (and I discovered this just today)

So I have no idea :/

navinp on 10 Apr 2018

I also don't understand:
Sending Test messages from the interface works fine

But when I go to for example the Reset pw page and try to reset my pw to see if emails are being sent, I get this:

We're sorry, but something went wrong.
If you are the application owner check the logs for more information.

Your netstat suggests you are running postfix mail server and PHP which means your server is obviously doing other things.

If you stop, disable, or remove Postfix, that should alleviate some of your problems.

willpower232 on 10 Apr 2018

I uninstalled Postfix, it seems to be working now.

Thanks very much.

Even though SMTP is working now, I get this (maybe after uninstalling php this will go better)

Okay, here's another update:
I removed php-fpm following the instructions found in this article: https://www.howtoinstall.co/en/ubuntu/xenial/php-fpm?action=remove

This is the result (think everything is working now):

The fast server is for click tracking so if you don't have a second IP on your server to use for the click tracking, you should probably disable it in postal.yml to make the error go away.
