I'm trying to config a postfix server to use for notifications of some my scripts.
The server should be able only to send email, not to receive them.
I'm within a company network.
I'm using a fake mail address to send the email.
Actually I can send email (and receive it to my true mail address) but postfix tries to send the same email to the the address I uses to send it (and it doesn't exist) creating an infinite queue.
Could someone help me to fix it?
this is my main.cf

# line of that file to be used as the name. The Debian default

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 have configured Postfix on my Ubuntu server to send/receive mails.
While the sending works perfectly fine but the receiving doesn't. I want to forward all received mail to my gmail account.
My /etc/postfix/mail.cf is as follow:
# See /usr/share/postfix/main.cf.dist for a commented, more complete version
# Debian specific: Specifying a file name will cause the first
# line of that file to be used as the name. The Debian default
# is /etc/mailname.
#myorigin = /etc/mailname

inet_protocols = all
And my /etc/postfix/virtual is:
#compzzz.com ramabc#gmail.com
Any mail I send to abc#compzzz.com, I receive a delivery failed email with unknown user error.
Am I going wrong somewhere?
Being unlucky to get any help from the techies out there forced me to go through the postfix documentation myself.
Just commenting the line which declared mydestination made it work.
i.e, replace the line
mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com
with
#mydestination = droplet1.compzzz.com, localhost.compzzz.com, localhost, compzzz.com, mail.compzzz.com
For forwarding emails to another address (other than your server), mydestination parameter isn't required, only virtual_alias_domains and virtual_alias_maps are required.
I have had a virtual postfix/dovecot/procmail server set up for some time, and for the most part everything is working fine. The only quirk that I can’t figure out is some virtual aliases seem to fall through to the virtual domain’s catchall mailbox rather than getting delivered to the intended virtual user. Not sure if it’s my postfix or procmail settings.
I've included below what I think is the relevant parts of the relevant config files. If you need more, let me know.
What's happening is that mail getting sent to troy#example2.com.au gets correctly delivered to /var/mail/vhosts/example2.com.au/troy
But mail sent to one of the aliases like info#example2.com.au does not go to /var/mail/vhosts/example2.com.au/troy but rather /var/mail/vhosts
What am I missing?

TBH, I don't know why this does not work, it looks fine to me. But you may try using a VirtualAlias to redirect info#example2.com.au to troy#example2.com.au.
Also, you should head over to ServerFault with that question - it's rather off-topic here.
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)
Hoping someone can help me out with this.

**Removed Sendmail
So i can receive an email from anywho#anywhere.com and i can now send to anywho#anywhere.com the only problem i have is that when i send to anywho#anywhere.com it comes though as me#gmail.com
I would like it to come through as me#mydomain.com
It looks like my sending domain has changed. Did i do something wrong
I could post my logs but they do not give any errors so im not sure how much that would help.
Anything else i can post let me know

You're using a relayhost.
It should go out as you#gmail.com because gmail swaps the sender to reflect your gmail account.
You can send email as you#domain.com only if you have a STATIC ip. Dynamic IP addresses are blacklisted by most email providers.
If you have a static IP, just remove: relayhost, *smtp_sasl_password_maps* and generally sasl unless you know what you're doing.
