Dear Christian, I am an "old" IT professional with 43 years of experience, retired last year and building my own "home lab" to keep my skills and "brain" up-to-date. I really enjoy your videos, my only advice is to "slow down just a bit" as we (old people) have a little bit of a hard time to "keep up with you". I saw that at one point you were having a "hard time" keeping with "other" you-tubers, just be your self! People will follow you because you add value to their professional (or in my case, retired ) lives. Keep up the good work! Regards, Pablo

I understand you, but for me who was looking for a solution for this, the video is gold. I know that there are a lot of key concepts not explained but at least now you know they exist and can look for them. It is fast but it is what you should expect by the title. All this just for saying I don't share the advice, everyone has different taste and needs. None can make a video perfect for everyone.

This was the best most painless setup I have ever done. I have been pulling my hair out trying to set up an email server that looked good and functioned well and I finally stumbled across this video. THANK YOU. Liked, subscribed and I will be anticipating a ton of good content.

This was an incredible video showing how to setup mailcow. Yeah, I love how you explain it and really build my knowledge. I do Teach also, and I communicate very similar to you. So, I appreciate what you are trying to do with your Teaching Style. I think this is one of the best channels on KZread for Linux education. I am learning so much for you. It is a big goal of mine to get a mail server up & running. But, I also want to write some filters to redirect emails into different user-accounts, because I get a shitload of emails a day that I need to manage somehow.

Great video and by far the best tutorial I've seen so far. A couple notes: you've also made a great text tutorial to look at alongside here (again, the best I've seen), however you skip a few minor commands as you just hop around with cd or open files. If it were really an absolute beginner watching, that would be game over. Also, dark blue on black is brutal if you're trying to track somebody else's console in a video. All in all, still fantastic and worth a like.

@christianlempa

One benefit of docker is that all containers are isolated from the underlying hostsystem. You don't need to uninstall them. However, what happens when you start the containers is that they try to listen on networkports on the hostsystem (this is called expose). You can only have 1 application that listens on a port and therefore the containers may fail to start. In this case you need to stop the applications on the hostsystem that listen on these ports (like in your case dovecot and postfix). Hope this helps

i can send emails to clients but when a client sends an email to the server then it times out the session.

So, in the last 1 minute we learned the most important of them all - that there's much more to do in order to have a functional email server... do you have videos for each of the needed thing? Thanks!

Master, have a nice day, I have a question, I have a local server with my web page running on apache 2, can I have both services (web server and mail server) running at the same time? With the same domain

Also, a comment on an aside, please, be careful with the sound level of music (if you could). I would have to turn down the volume at the Slide pages, so I wish it was same volume as rest. Also, music is nice, but it is very loud. I'd maybe have it slightly audible. Because all of us are here for you and learning from you. I don't care extremely about the music and about it being "Fancy". Your teaching method, style, and care for your students (i.e., the audience) is enough to draw me back to watch every video that you have produced and/or will produce. Also, I am adding you to my Patreon subscriptions. I think that I've done it already, but I am going to check again just to make sure. Also, if on Patreon, you have it higher than (say) $1 dollar, always set it that low. Then, people join it, get benefit over time, and will give more. I hate when people have it like $5 bucks or $10 bucks. Well, I don't always start out there, if that makes sense.

Hi, amazing videos, very simple and straight to the point but i have a problem. On my machine i have a portainer to manage my container and on top i have an NginxProxyManager and, even if i change the port of HTTP/HTTPS on mailcow.config, i can't run and access mailcow. There is a way to run mailcow and use the nginxProxyManager container that i have or to bind the mailcow access port with the nginix container?

@christianlempa

3 жыл бұрын

Thank you, glad that you like it! 😉 I'm not so familiar with portainer or nginxproxymanager, but I assume in this case you would need to modify the docker-compose file of mailcow that it doesn't expose the ports to the hostOS. Then on nginxproxymanager you should be able to create a reverseproxy to the internal ip of the nginx docker container of mailcow? Well that's just an idea, I probably would need to look into it because I just have deployed mailcow out-of-the-box right now. But I want to work on a kubernetes deployment of mailcow, then I will need to look at this anyway 😁

Hello! you said it is recommended to install into /opt. If I want to use a different hard drive for mailcow mailbox storage. Would the best solution be to mount /opt to that second hard drive, or does mailcow have an option, once setup, to change the mailbox storage location? Thanks for your time and for making this video. I'm excited to give this a try!

Thank you so much ;) It's not really important in which folder you place the project, the /opt is just mentioned in the official docs and follows the linux filesystem BPs. But you could also just put the project completely in a different folder or mount the second harddrive to the /opt/mailcow folder. It doesn't make a difference for mailcow itself where it's placed.

Agree with C. Lempa that sending cold-call emails is effectively spamming. But if you must do it, then send from a professionally hosted mail service like those offered for ~ $2 - $5 a month by hosting companies. Sending them from your own mail server you will soon have your server IP reported for spam and all other things on that server machine shut down. As well as the risk of being spammed or DOS-attacked yourself.

You need to use different ports for your mail server. You can change them in the mailcow.conf

When I try to bring it up with docker compose, it errors out with "failed to create network mailcowdockerized_mailcow-network: Error response from daemon: Pool overlaps with other one on this address space". It would help if it actually stated what "address space" it's trying to take so I could free it up. I'm hoping to replace Luke Smith's Postfix setup from his Github script so I can actually point a frontend admin panel at MySQL to administer my mail server, so I'm guessing it's conflicting with that somehow. However, using "systemctl stop postfix" doesn't seem to free up whatever nebulous thing mailcow is trying to set up at this point.
