I just deployed with iredeasy to a new droplet on DO. It went flawlessly, and I added a letsencrypt certificate. Sending and receiving email works great and received no certificate popup when I configured an outlook email client on ports 995 and 587 (so i assume cert was installed correctly).

I am getting the error message when I try and send form mail through ActionMailer in my ruby on rails website in both development and production mode.  These forms have been running for years connected to a different iredmail server version 0.9.5-1, Ubuntu 16.04.5 LTS, and Apache2, and MYSQL.

I just changed the following to conform with new server:

deveopment.rb and production.rb

config.action_mailer.delivery_method = :smtp
config.action_mailer.default_url_options = { host: 'underwoodlaw.net' }
ActionMailer::Base.smtp_settings = {
      :address => 'mail.underwoodlaw.net',
      :port => '587',
      :authentication => :plain,
      :user_name => ENV['UNDERWOOD_USERNAME'],
      :password => ENV['UNDERWOOD_PASSWORD'],
      :domain => 'underwoodlaw.net',
      :enable_starttls_auto => true

local.env.yml

UNDERWOOD_USERNAME: 'steve@underwoodlaw.net'
UNDERWOOD_PASSWORD: 'xxxxxxxx'

application_mailer.rb

class ApplicationMailer < ActionMailer::Base
  default from: "steve@underwoodlaw.net"
  layout 'mailer'
end

contact.rb

def headers
    {

        :subject => "Web Consultation Request",
        :to => "steve@underwoodlaw.net",
        :from => %("#{name}" <#{email}>)

    }

Although it is true that I had to make the following adjustments on the old server to make the old server work, I get no error message if I use the test SMTP server at https://www.gmass.co/smtp-test, on the new server with the same setup as above.

Adjustments were made on old server because I was using a form on a website on Domain A, to send email through a mail server on  Domain B.
The new mail server is on the same domain as the website but on a separate droplet from the website.
I am quit sure my DNS is set up right with the correct things like at https://docs.iredmail.org/setup.dns.html.

Adjustments made on old server:
1) /ect/postfix/main.cf: Added:      smtp_header_checks = regexp:/etc/postfix/smtp_header_checks

2) /etc/postfix/smtp_header_checks:  Added:
/^Received: .*/     IGNORE
/^X-Originating-IP:/    IGNORE

3) /etc/amavis/conf.d/50-user:  Added a couple more domains (new server only has one).

4) /opt/iredapd/settings.py

Removed 'greylisting' from plugin section

ALLOWED_LOGIN_MISMATCH_SENDERS = ['noreply@iexample.com, 'noreply@example2.com']

MYNETWORKS = ['webserver-ip', 'home-ip - for development mode']

ALLOWED_FORGED_SENDERS =  ['website.com]

5)  /etc/postfix/main.cf Added: mynetworks= 127.0.0.1, home-ip, website-ip

I have tested the new server modifying it to match the old server for testing purposes, but still get same nondescript error.
I turned on the debug_peer_list = "" to get a better log but when the submit is pressed it gets to the point in the log where anonymous TLS connection established but then goes directly to NOQueue
Client host rejected: Access denied 554 5.7.1.

Been working on this for 2 days unsuccessfully. Help would be appreciated.

Please show us the original and full log line, this one was trimmed.

All your modifications (steps 1-5) are unnecessary and probably wrong. please revert it.

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

Re: Client host rejected: Access denied 554 5.7.1

I noticed something I thought was strange in my  /etc/postfix/main.cf file.

mynetworks = 127.0.0.1 [::1]

Is the [::1] supposed to be there?

Perhaps it helps with the  /opt/iredmail/custom/ system you have going with IredEasy?

Re: Client host rejected: Access denied 554 5.7.1

Yes all those settings 1-5 have been reverted before I posted the postconf -n.

I only did it for testing purposes.

here is the last 200 lines after i just submitted the form again:

Re: Client host rejected: Access denied 554 5.7.1

Just for more information I tested a node.js app I made with the following code and the email was delivered. The request was made from the same ip address on my home computer like i was useing in the rails app. Emailjs can be found here: https://github.com/eleith/emailjs.

This makes no sense to me.

------------------------------------------

var email = require('emailjs');

var server = email.server.connect({
  user: 'steve@underwoodlaw.net',
  password: 'xxxxxx',
  host: 'mail.underwoodlaw.net',
  tls: true
});

server.send({
  text: 'Hey howdy',
  from: 'steve@underwoodlaw.net',
  to: 'Steve <steve@underwoodlaw.net>',
  cc: '',
  subject: 'Greetings'
}, function (err, message) {
  console.log(err || message);
});

Re: Client host rejected: Access denied 554 5.7.1

I have tested everything I can think of including making another form that sends html, because the form in post 7 sends the email in plain text, that worked as well.

I am sending from the same ip address using the rails app that I am in post 7, and the rails app is rejected but post 7 works.

If I send the rails app form through my other iredmail server it works fine (only difference is the version of iredmail, and it uses the stock certificate instead of letsencrypt.)

All of these tests were done with the default configuration as posted in post 6 on a new server as described in my first post.

Any ideas anyone?

Re: Client host rejected: Access denied 554 5.7.1

OK I got it working but I am not sure if I did it correctly (at this point i don't really care).

First,  ZhangHuangbin, if you developed iredmail you are one smart dude. There is so much going on with this, and so many services running, I can't wrap my head around it. Normally I can figure out how

anything works but this not so much.

ZhangHuangbin you were right about the the modifications I made to my old iredmail server: Steps 1-5 were mostly unnecessary and wrong. I went back and reconfigured them and found I only needed to have
ALLOWED_LOGIN_MISMATCH_SENDERS = True, in the iredapd settings for the other server to work when sending a rails form when the mail server was on the same ip address as the website contact form.  I

needed the mismatch sender modification because the rails mail_form gem uses the email address in the contact form, (ie. email address of person filling  out the contact form), instead of the default email address

sender that is set forth in application_mailer.rb.

The new iRedeasy server was a differen story. With the default settings, the form would not send at all (Client Host Rejected), but of course the javascript one would so long as the "from: field" matched the

account that I was using to access the SMTP server. Adding a custom setting in  /opt/iredmail/custom/iredapd/settings.py,  ALLOWED_LOGIN_MISMATCH_SENDERS = True, fixed the issue on the javascript

form, but still got the evil "Client Host Rejected" on my rails contact form.

At this point, nothing made sense and still doesn't. Keep in mind, that my new setup is that my rails app is running on one droplet and the mail server is on another (2 different ip addresses). They both share the

same domain with the mail server being on a subdomain. There is an A record pointing to the mail subdomain that directs to the mail server droplet ip, and a MX record pointing the domain that says that the mail

is handled by the mail subdomain. Also keep in mind that the javascript form is working.

Here is what I had to do to fix it:

nano /opt/iredmail/custom/postfix/custom.sh

postconf -e mynetworks='127.0.0.1, 122.104.69.55, 162.27.127.16'   

postconf -P "submission/inet/smtpd_client_restrictions=permit_mynetworks"

bash custom.sh
sudo service postfix restart

The  122.104.69.55  =  The WAN IP of my home computer so I can submit the form in rails development mode.
The   162.27.127.16 =  The IP of the droplet were the rails app is running so I can submit the form in production on the apache2 webserver.   

Form some unkown reason to me the postfix master.cf setting of:  -o smtpd_client_restrictions=permit_sasl_authenticated,reject kept the rails app from submitting in both development and production modes,

even with starttls set to true in the configuration (:enable_starttls_auto => true).

Both the javascript form, and the rails app, seemed to be connecting and authenticating through tls accourding to the logs.

Before I stumbled onto this fix, I tried  upgrading rails from 5.0.0.1, to 5.1,  but it did not help.

ZhangHuangbin, if you know what is causing this problem I would be interested in knowing.

The logs are really different on a successful submission between the javascript form and the rails form.

Will post the in two separate posts after this one.

Re: Client host rejected: Access denied 554 5.7.1

So sorry about my late reply.

Please read my full reply in this post BEFORE you change any settings on iRedMail server, because you don't need to change anything on iRedMail server.

It was "caused" by one rule in file /etc/postfix/rdns_access.pcre (used in postfix main.cf, parameter "smtpd_client_restrictions"), you can check it like this:

# cd /etc/postfix/
# grep 'cpe' rdns_access.pcre  | grep rr
...
/^cpe(-[12]?[0-9]{1,2}){4}\.[a-z]{2,6}\.rr\.com$/ REJECT Generic - Please relay via ISP (rr.com)

With this rule, connection from IP addresses (which resolved to DNS name "cpe-<ip>.<...>.rr.com") to port 25 will be blocked directly.

BUT we still allow connections from these (actually, all) IP addresses to port 587 (defined in /etc/postfix/master.cf, transport "submission"). This way we block all (bad) connections which trying to prevent they're a MTA and send spams, but still allows normal users who have a working smtp username+password to send emails.

According to pasted log in your 4rd reply in this thread, your application didn't perform SMTP authentication at all:

Nov  7 01:28:27 mail postfix/submission/smtpd[18491]: connect from cpe-172-101-69-50.buffalo.res.rr.com[172.101.69.50]

With smtp authentication enabled (on your application or MUA side) and working correctly, you should see log LIKE below among above log lines:

Nov 11 15:50:24 <hostname> postfix/submission/smtpd[5796]: <queue-id>: client=<hostname>[<remote-ip>], sasl_method=LOGIN, sasl_username=<full-email-address>

You may feel weird that your application did have smtp authentication enabled, but i'm just telling the fact based on your  pasted log, it didn't enable smtp auth.

Does my reply help a little? How about buying me a cup of coffee ($5) as an encouragement?

Re: Client host rejected: Access denied 554 5.7.1

What you said in Post 12 makes perfect sense to me. I will revert that setting  and see if I can figure out why the app is not authenticating  SMTP.   Thanks for your reply, and for figuring out the problem even though it was never an iredmail issue.

14

Re: Client host rejected: Access denied 554 5.7.1

OK I figured it out finally.  The problem was I was using local_env.yml to bring in the authorization credentials, and they were not being imported or used to make the secured connection on port 587, so smtp auth was not working (just like you said in your last post).

This following section of production.rb and and development.rb, setting up the smtp credentials.

:user_name => ENV['APP_USERNAME'],
:password => ENV['APP_PASSWORD'],

The problem was that I had nothing in my application.rb to do the importing and parsing (you would think that you would get an error message from rails about it).

If you use this method and store your credentials in local_env.yml the you need the following code inside you app beginning with config.before...


module YourApp
  class Application < Rails::Application

    config.before_configuration do
      env_file = File.join(Rails.root, 'config', 'local_env.yml')
      YAML.load(File.open(env_file)).each do |key, value|
        ENV[key.to_s] = value
      end if File.exists?(env_file)
    end

  end
end


That fixed it so I only need one modification (ALLOWED_LOGIN_MISMATCH_SENDERS = True)
and I reverted all the other changes.

All that drama for just that.

Thanks,  ZhangHuangbin I would never have figured it out without your last post.
