I can't figure out how to get DKIM working on the secondary install of Postfix (https://unix.stackexchange.com/a/179175/102085)
Putting
smtpd_milters = inet:127.0.0.1:8891, inet:127.0.0.1:8893
non_smtpd_milters = $smtpd_milters
On the /etc/postfix-secondary/main.cf doesn't work.
I believe I have everything else set up correctly.
/etc/opendkim/KeyTable -

I am stuck for some time trying to set up an email server. I've been mostly successful in my setup, but I am currently stuck at the following impasse: every time I send an email (regardless of queue size), my message will get stuck in the active queue for ~ 5 minutes, after which it will always be sent and reach it's final destination.
postqueue -p
(shows only one mail in the queue)
postqueue -f
... has no effect
I am running postfix 3.1.0, and dovecot 2.2.22 on Ubuntu 16.04. Also, I used iRedMail scripts for the installation. I can see from /var/log/mail.log that the mail is being stored in a queue by postfix, and I'm assuming there's another setting to set the time at which it will be processed. Any help would be most appreciated.

It looks like the ClamAV hangs and times out after 5 minutes. Would that explain things? I find it hard to read your configurations.
I have configured postfix to send received email to local LMTP agent using virtual_mailbox_domains parameter it works fine if the received email is received for FQDN of the machine running postfix but if it's for the IP address of the machine then it throws the following error "Recipient address rejected: User unknown in local recipient table". Tried different things but no luck. I would really appreciate any tips on this scenario.
Thanks for your help in advance!
Here is the topology:
IP FQDN
Machine A (sending machine) 10.2.20.40 machine-a.test.com
Machine B (Postfix + LMTP) 10.2.20.50 mta.test.com
Machine B is running postfix + custom LMTP.
Example 1 (succeeds)
Send email to user#mta.test.com from Machine A. This use case succeeds and Postfix successfully delivers email to customer LMTP agent listening on localhost's socket.
Success case /etc/postfix/main.cf:
virtual_mailbox_domains = mta.test.com
/etc/postfix/virtual_mailbox_map:
user#mta.test.com lmtp:inet:127.0.0.1:5678
Example 2 (Failed case)
Send email to user#10.2.20.50 from Machine A. This case fails and Postfix throws this error in mail.log "NOQUEUE: reject: RCPT from unknown[10.2.20.40]: 550 5.1.1 : Recipient address rejected: User unknown in local recipient table; from= to= proto=ESMTP helo=<[127.0.1.1]>"
Failure case /etc/postfix/main.cf:
virtual_mailbox_domains = 10.2.20.50
/etc/postfix/virtual_mailbox_map:
user#10.2.20.50 lmtp:inet:127.0.0.1:5678

user#10.2.20.50 is incorrect syntax.
user#[10.2.20.50] is what the RFC allows for.
But anyway: Since Postfix says "User unknown in local recipient table", the domain part is considered to be local. Not virtual.
You could try adding:
[10.2.20.50] is_a_virtual_domain
user#[10.2.20.50] someother#address
to virtual_alias_maps and check if it works, but I'm not sure about this at all.
#[10.2.20.50] syntax is rather byzantine.
I'm setting up my mail server and I followed that tutorial https://www.linode.com/docs/email/postfix/email-with-postfix-dovecot-and-mysql to help me doing so. Everything went fine during the setup and configuration but when it went to test problem started. From what I've tested I can log in just fine and the logs shows me that the connection has been accepted, but when I want to receive or to send a email I start to see errors like the following line :
server postfix/smtpd[28557]: error: unsupported dictionary type: lmtp
I searched a lot online but I can't seems to find any resources about that specific error. Running postconf -m doesn't show me "lmtp" but I'm not sure if it's normal or not.
Would anyone have any suggestions?

You should remove space at beginning of the line:

I am configuring Postfix and when validating by telnet and SMTP I got the status bounced error, unknown user:
Error log:
postfix/local[18718]: 4590D7DC0A51: to=myuser#mydomain.example, relay=local, delay=9.8, delays=9.8/0.01/0/0.04, dsn=5.1.1, status=bounced (unknown user: "myuser")
The "myuser" already exists, but with full domain name: myuser#mydomain.example.
User Validation:
postmap -q myuser#mydomain.example mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf
Output is: "1" - so I guess it is OK.

you have added mydestination = mydomain.example and so the valid users for mydomain.example will be searched in local_recipient_maps. It is very clear from the logline that local delivery agent is selected to deliver the mail, as local domain class matched. See postfix address classes for more help
Modify your main.cf like below
#/etc/postfix/main.cf
mydestination =
# set to localhost localhost.$mydomain or remove mydomain.example for now
# Ensure that postmap -q mydomain.example mysql:/etc/postfix/mysql-virtual-mailbox-domains.cf is returning mydomain.example and
# postmap -q myuser#mydomain.example mysql:/etc/postfix/mysql-virtual-mailbox-maps.cf succeeds
Open /etc/postfix/main.cf, look for the mydestination field and change it's value to the below
mydestination = localhost, localhost.localdomain
Don't forget to run sudo postfix reload afterwards
Use following settings in /var/postfix/main.cf
myorigin = localhost
myhostname = <your_host_name>
mydestination = localhost.$mydomain, localhost, localhost.localdomain
followed by:
sudo postmap /etc/postfix/virtual
sudo service postfix restart
For someone else, when I set mydestination=mydomain.example.
Postfix show warning do not list domain mydomain.example in BOTH mydestination and virtual_mailbox_domains. So I set it relayhost = mydomain.example
My postfix version: 3.1.0 (postconf -d | grep mail_version)
I'm using Thin as a server for Faye. To do that, I use something like this:
require 'faye'
bayeux = Faye::RackAdapter.new(:mount => '/faye', :timeout => 25)
bayeux.listen(9292)
The Thin process is monitored by God and all is well in Development.
However, I'm not sure if this is the right setup for a production configuration. What I would like to know is how is this setup (with no Nginx or HAProxy at the front) is going to perform in a production environment.

and i'm using nginx to load balancing.
I have been using thin to run faye with redis. making sure to set
Faye::WebSocket.load_adapter('thin')
all traffic goes through haproxy (the first one is named proxied as I redirect all traffic to https)
frontend proxied
bind 127.0.0.1:81 accept-proxy
timeout client 86400000
default_backend nginx_backend
acl is_websocket hdr(Upgrade) -i WebSocket
acl is_websocket hdr_beg(Host) -i ws
use_backend socket_backend if is_websocket
backend nginx_backend
balance roundrobin
option forwardfor #except 127.0.0.1 # This sets X-Forwarded-For
timeout server 30000
timeout connect 4000
server nginx1 localhost:8081 weight 1 maxconn 20000 check
backend socket_backend
balance roundrobin
option forwardfor except 127.0.0.1 # This sets X-Forwarded-For
timeout queue 5000
timeout server 86400000
timeout connect 86400000
server socket1 localhost:3100 weight 1 maxconn 20000 check
server socket2 localhost:3101 weight 1 maxconn 20000 check
server socket3 localhost:3102 weight 1 maxconn 20000 check
server socket4 localhost:3103 weight 1 maxconn 20000 check
...
if it is http traffic I route it through nginx which forwards to the same set of thin instances if it includes the /faye path.
I am not an haproxy expert but this is working for websocket and long poll connections.
