Hello,
I would like to send mail from app service
by using mail
command like
echo "hello" | mail -s "test subject" -r [email protected] [email protected]
but this mail is not working.
If I use same mail command from smtp service
then I am always get mail to mailbox.
If I use heirloom-mailx then it is working from app service
apt-get install heirloom-mailx
echo "This is the message body and contains the message" | heirloom-mailx -v -r "[email protected]" -s "This is the subject" -S smtp="smpt:25" [email protected]

I try to install ssmtp on the app service
but it is not working too.
apt-get install ssmtp
and set set up config like
> cat /etc/ssmtp/ssmtp.conf
root=postmaster
hostname=dc4285ba769a
mailhub=smtp:25
Thank you for help
entrypoint.sh contains the following conditional block that is either incorrect or unnecessary:
if [ "$MAILNAME" ]; then
echo "MAIN_TLS_ENABLE = yes" >> /etc/exim4/exim4.conf.localmacro
s
else
echo "MAIN_TLS_ENABLE = yes" >> /etc/exim4/exim4.conf.localmacros
fi
I suspect that the else clause should be setting MAIN_TLS_ENABLE to no if there is MAILNAME variable set, but I could be mistaken.
How can I integrate with Traefik for SSL and more?
Hi there, just wanted to say thanks for putting this docker-based smtp server together. It works as expected. Thanks again and good luck!
Problem
Hi, I am using namshi/smtp
to be my smarthost SMTP relay for SendGrid. I need to enable TLS so that the SMTP replay only handles requests with certs. Therefore, I set the values for CERTIFICATE_PATH
and KEY_PATH
to enable TLS.
Performed
I ran the following command to initialize the container:
docker run -p 25:25 -v $(pwd)/:/etc/ssl/certs \
-e "KEY_PATH=/etc/ssl/certs/MyKey.key" \
-e "CERTIFICATE_PATH=/etc/ssl/certs/MyCertificate.crt" \
-e "SMARTHOST_ADDRESS=smtp.sendgrid.net" \
-e "SMARTHOST_USER=apikey" \
-e "SMARTHOST_ALIASES=*" \
-e "SMARTHOST_PORT=587" \
-e "SMARTHOST_PASSWORD=MY_API_KEY" \
namshi/smtp
Then I sent a testing email with this code
Expected Result
The email is supposed to be blocked because no cert is provided.
Actual Result
The email is sent.
Any suggestions?
Hi, is there chance to tag version of your image, im trying to make sure that my application will be always built and I had some troubles with images at latest version.
Is there any reason for not creating concrete version?
Hello I am simply trying to send mail using smtplib.
I added the certificate to the smtp container, and when I ran that code, this '550, b'relay not permitted' occurred. It seems that it cannot be received from other receiving servers.
Please help.
Thank you.

to_email = data.get('to email')

app.run(host='0.0.0.0', debug=True, port=5050)
When connecting to Gmail via the $GMAIL_USER
and $GMAIL_PASSWORD
env variables, Google bugs me about it being a 'less secure app'. I tried enabling less secure apps, but it is a pain and it reverts back if no emails are sent for a few days.
According to Google, I should use OAUTH, is there a way to use it with this container?
Hey,
My PM noticed that the new smtp cluster based on this image is much slower than the classic IIS smtp for example, does anyone experience that aswell?
Moreover, since i believe that it is something related to the queue, i took a look at the logs and found that:
Is that a valid log? why does the queue start&end so many times?
Is there any way to make my swarm cluster work faster?
Thanks alot!
I tried using sendgrid and everything is fine.

Is possible to add feature where the container would pipe request to docker logs and not send email? This would be helpful when using this image during app development.
Is it possible to use user and password to raise just the SMTP Server?
many thanks
I have the image running with gmail user and gmail password set. How do I send mails now?
In a deployment I saw this error:
all relevant MX records point to non-existent hosts
After some research I discovered the ignore_target_hosts
configuration option. This was configured in both:
/etc/exim4/conf.d/router/200_exim4-config_primary
/etc/exim4/exim4.conf.template
Since my MX server's A records record resolves to an address in the 10.0.0.0/8 it was being ignored as a viable host. I had to modify both configuration files and reload the service in order to send messages.
Can we add environment variables to allow modifying this configuration option?
what environment variables do i actually need set to relay all incoming emails to a remote postfix server. please could you give an example?
Hi,
Using your image on local linking with docker-compose, it works like a charm.

Docker doesn't seem to route ipv6 without starting it with --ipv6

The only difference is that I had to specify RELAY_NETWORKS=:10.7.0.0/24
for weave.
Any idea how to solve this issue ?
I saw there is some disable_ipv6

Hi, I have a application running inside docker container, and my application has a functionality of sending emails to the registered user.
Problem :
I believe the smtp support has not added to the docker container, can you please let me know on how to add the smtp server, so that i can send email from the application.
I have an email like, [email protected] which is my organization email id and i want my application to send an email to the users using [email protected] as from address.
Smtp does not seem to accept including 8 bit letter that are mime coded
As a security measure, the Dockerfile should have a USER directive in order to run using a non privileged user account.
Can you add it ?
I am trying to have gmail relay and it does not work in my company network, the same container works fine in my home network. I am trying to figure out the network restrictions using the logs but with no luck. Below are the logs for both cases.

There is no error but it just stucks at this point and does not go any further. Can you please suggest what is happening. The step: SMTP<< 220 smtp.gmail.com ESMTP u3sm4885654pfu.5 - gsmtp
is not being performed in the case it is not working. What does it mean? What could be the network restriction to address?
Thanks a lot!
Thank you for this image, very useful. Can you please add release tag to docker hub, we need fixed version some times.
When running this container, which directories do I need to declare as volume so that the queued messages would not be lost during restarts?
someone will have to rebuild and republish this package bundling 4.89-2+deb9u4
or higher.
After setting KEY_PATH and CERTIFICATE_PATH I do not have TLS enabled. I can see that it finds the certs, it copy's them over successfully, then the daemon starts without TLS.
exim 4.89 daemon started: pid=1, -q15m, listening for SMTP on port 25 (IPv6 and IPv4)

Hi,
it would be great if you could write a sentence or two on how to integrate own configurations into the container.
If managed to get DKIM working by bind-mounting over the generated exim4.conf.localmacros like
- ./00_local_macros.txt:/etc/exim4/exim4.conf.localmacros:ro
however, now I want to add a new config that would add VERP by mounting it into
- ./verp.conf:/etc/exim4/conf.d/rewrite/40_exim4-config_verp
but as the container is using a single-config file, it won't pick up this config.
I don't want to bind-mount the whole config file into the container, as then I would lose the flexibility gained by your sed-replacements (ips and so on..)
any hints / suggestions are highly appreciated!
I'm trying to increase the amount of emails this would accept from 10 to 100, but no matter where I put the config it is not being picked up when I restart the exim4 service. Can someone let me know where I'm supposed to put this?
would be nice / convenient if there were ways to rewrite TO and/or FROM fields. using this as a very simple relay for a home lab would like to rewrite all TO fields to my email account regardless of the original TO. I would assume that the ability to rewrite FROM to @example.com would also be a benefit to some.
thanks!

It seems that the SMTP is not accessible from the Contact Form 7 WordPress plugin which I use through the REST API. How can I test the smtp container in a fast and good way or how can I change the docker-compose.yml
file to make it work?
When I run $ docker-compose up
I do not get errors.
The JSON object I get in the browser is this:
{into: "#", status: "mail_failed", message: "There was an error trying to send your message. Please try again later."}
The related forum question is here.
Thank you.
Hey,
I have few SMTP containers under AWS load balancer.

It would be great if there were an option to disable **host_lookup = **
Inside the config file which is generated from exim4.conf.localmacros and exim4.conf.template of this solution.
awesome image. the only thing missing for me at the moment is DKIM support.
I found this article, that describes on how to setup it.
Do you have a suggestion what would be the best way to incorporate it into your image? Then I could try to do that during the weekend.
Trying to use this container as a service in my docker-compose.yml this way however I'm receiving an error:
"No connection could be made because the target machine actively refused it 127.0.0.1:25"
smtp:

container_name: jn_smtp_gmail
environment:
- RELAY_NETWORKS=:192.168.0.0/24
- GMAIL_USER=<email>
- GMAIL_PASSWORD=<password>
networks:

Not sure what is wrong? Can you pls shed light on this?
Please note that I'm trying to call the container from a local application and not an internal container within the docker network
A few days ago, Debian announced the removal of non-LTS Jessie from their mirrors:
https://lists.debian.org/debian-devel-announce/2019/03/msg00006.html
This causes problems when trying to use the namshi/smtp docker image:

Would it be possible to switch to Stretch?
There were a bunch of exim4 security updates announced today, including several remote code executions.
https://lists.debian.org/debian-security-announce/2021/msg00093.html
The fixes are in buster, so it should be a matter of rebuilding images to pull the latest packages from there.
Can you please do this and push to docker hub?
When configured as a relay docker-smtp doesn't support a TLS-only smart host. TCP connection can be initiated on port 465 but then docker-smtp doesn't even try to initiate the TLS connection.
Would it be possible to get the SMTP relay to support sending email via AWS SES via the API rather than relaying it to the AWS SMTP endpoint? This would allow us to just use an IAM role to authorize the sending of the email rather than generating the corresponding SMTP credentials for an IAM user.
As of October 14th, this docker stopped working with my gmail account.
I manually changed the passwd.client
from *.google.com:
to *.gmail.com:
and that appeared to work.
Not sure why this broke all of a sudden on a version of this image that was 2 years old running in a container up for over 7 months. I tried pulling the latest version and it still didn't work until I made the google
->gmail
change.
I was getting "Authentication Required" errors

If docker has to restart a running container (server reboot, docker service restart)
The container is not able to come back up.
I think this was caused by my changes for #5 .
Adding this as a placeholder so people know there is an issue and I'm looking into it.

Hi, I really appreciate this image and am now trying to get it working on my Google Cloud VPS. As you may already know, they block the normal outgoing ports for SMTP. As I was figuring this out, I ran across this stackof: http://stackoverflow.com/questions/24834047/amazon-ses-on-google-cloud-computing-instance-vm-using-postfix
Is this possible to include in your .sh?

Hello, not sure to write it here, but I can't solve the problem by myself, so...
I used this docker image to run as single smtp server for web app via docker-compose.
Compose configuration:
smtp: image: namshi/smtp:latest networks: - nginx_ext_network environment: MAILNAME: 'mailer' restart: always ports: - "25:25"
But then the web app require to send an email, smtp server tries to do it, but fails.
I tried it multiple times. With different ports. With different emails. Nothing works.
Can you help me? Maybe some problem with my configuration? Or maybe you've seen this before?

I just run with the below command:
docker service create \
--name smtp \
--mode replicated \
--constraint 'node.hostname == xxx' \
--env [email protected] \

--publish 33338:25 \
namshi/smtp
Then I got:

What am I missing?
Running docker-smtp in docker swarm or as a service with
docker service create --name smtp -p 25:25 --replicas 1 namshi/smtp:latest
fails to start the container with the following error reported in the logs:

It would be great if this image could be used in swarm mode.
hi,
how would I in the best manner make the letsencrypt certfile and keyfile available.
I tried setting the env variables
CERTIFICATE_PATH=/etc/letsencrypt/archive/xxx/fullchain1.pem
KEY_PATH=/etc/letsencrypt/archive/xxx/privkey1.pem
but the container wont start up with the message:
cp: cannot stat '/etc/letsencrypt/archive/xxx/privkey1.pem': No such file or directory
Not totally sure why this is, but I have to 'allow less secure apps' in order to use the gmail relay setting. I get an email like:
Hi XXX,
Google just blocked someone from signing into your Google Account [email protected] from an app that may put your account at risk.
Less secure app
Friday, March 10, 2017 10:41 AM (EST)
Ashburn, VA, USA*
Don't recognize this activity?
If you didn't recently receive an error while trying to access a Google service, like Gmail, from a non-Google application, someone may have your password.
SECURE YOUR ACCOUNT
Are you the one who tried signing in?
Google will continue to block sign-in attempts from the app you're using because it has known security problems or is out of date. You can continue to use this app by allowing access to less secure apps, but this may leave your account vulnerable.
Best,
The Google Accounts team

I executed the following commands
docker run -p 2587:25 namshi/smtp
Soon after I released port 2587 from my internal network so that my other server could see.
Then I executed the command below to check the problem.
docker exec -i -t fe6e205955e1 /bin/bash
I tried pinging out ... Ex: ping 8.8.8.8
He can not even drip ...
Should we do anything else to solve this problem?
Hi,
I was trying to use your container as a simple smtp server (without any relay). I've build the image from source and successfully ran it. The question is how can I configure it. Thought I can use the following command
sudo dpkg-reconfigure exim4-config but unfortunetely not able to attach to the running container, even when it was started with -itd options.
