I went with Mailcow โ it's a dockerized mail server suite that bundles Postfix, Dovecot, Rspamd, SOGo, and a web UI. There are other solid options like Mail-in-a-Box or rolling your own with Postfix + Dovecot, but Mailcow hits the sweet spot between control and convenience. - Source: dev.to / 3 months ago
> Wow... Having just gone through a 20+ hour byzantine nightmare of setting up postfix & dovecot Did you do this by hand / manually, or use a 'pre-canned' solution like: * https://mailcow.email * https://workaround.org. - Source: Hacker News / over 1 year ago
I've been running mailcow for a long time to _receive_ mail. Sending was hit and miss. For a long time I could relay through my ISP, but that got me into delivery problems as well. Now I've been relaying through Mail.baby/Interserver for 18 months or so and it works great. $1/mo base fee + usage. With the <100 mails me and my family send that adds up to $1.01/mo. https://mailcow.email/. - Source: Hacker News / over 1 year ago
If you had a server around, considering just setting up https://mailcow.email/ it's super easy and straigforward. Everything is in docker compose. `docker compose up` and you go. If you want a hosted SMTP for your own single domain, and volume is low, consider just using AWS SES. I run betterdev.link with it, send about 20k email per months and pay around $2 If finally you want some nice and easy UI to use for... - Source: Hacker News / over 1 year ago
You could go with https://mailcow.email, it's pretty easy to setup and keep up to date. - Source: Hacker News / almost 2 years ago
> Which different provider did you go with? I actually fell back to Gmail for the time being - I just don't like to "advertise" any Google product for known reasons, even though Gmail is a quite solid product, sorry about the confusion - but that's my temporary solution. I am planning to either give Migadu a try or host my own mail provider. (I have seen some good feedback about https://mailcow.email). - Source: Hacker News / about 2 years ago

You can self host email if you really want to, but it's really more trouble than it's worth. If you do self host, you have to worry about the consequences of missed emails if your server or Internet ever goes down, and you'll have to use someone else's SMTP server if you don't want your emails to go directly to spam. The cheapest good SMTP server is Amazon SES, which I believe is $0.10 per 10k emails. I've been... Source: about 3 years ago
However, https://mailcow.email/ is the ONLY exclusion I make for that. As it's an all in one docker managed solution. Where the only things you have to worry about is the reputation of your mailing IP. Source: about 3 years ago
But its probably easier to use a dockerized container with all the mail stuff integrated and pre-setup like: https://mailcow.email/. Source: about 3 years ago
What is it all about with mailcow.email and access to docker socket? Does mailcow require access to it? Why? And how it is bad? Source: about 3 years ago
Or, you can keep your VPS running 24/7, with mailcow.email for your emails, immich.app for your photos, nextcloud for your calendar and contacts. Use a second SMTP relay as a backup, they will receive your emails if your main SMTP is down for more than one week, which is the procedure. Source: about 3 years ago
Mailcow is pretty popular from what I gathered. Source: about 3 years ago
Have a look at mailcow. Been running it in a VPS for several years now and it's very reliable. Source: about 3 years ago
I'm telling you that you could setup a host in my cluster and it will work though (would need to setup a mail proxy though as I currently operate). I operate from centurylink (Although there's new fiber being run in my neighborhood and hot damn am I so happy, so my provider might change). And I operate mailcow (https://mailcow.email/).

For a self-hosted option you could take a look at https://mailcow.email. I think I saw some way to connect it with NextCloud, but I donโt use it, so not sure. Source: about 3 years ago
Not sure why anyone hasnโt mentioned MailCow yetโฆ I would advise against self-hosting your mail server for several reasons (I do it) but if you are going to regardless; I think this is you best option. Only took me ~45 mins start to finish. Source: over 3 years ago
Mailcow has emerged as a notable contender in the realm of self-hosted email solutions, drawing attention for its robust feature set and open-source nature. Positioned in a competitive landscape against the likes of Mail-in-a-Box, iRedMail, Zimbra, Roundcube, Modoboa, Mailu, and Postfix, Mailcow offers a compelling alternative to traditional email service providers, particularly for businesses and tech enthusiasts interested in maintaining control over their email data.
At its core, Mailcow is a Docker-based email server suite. This architecture allows it to leverage containerization, thereby delivering a modular and scalable solution. Each componentโsuch as Dovecot, Memcached, MySQL, PHP, Postfix, and Nginxโis encapsulated within its own container, facilitating easier management and deployment.
Mailcow is recognized for its comprehensive web user interface that simplifies administrative tasks. This UI supports both granular administrative roles and user management, making it suitable for organizations managing multiple domains and inboxes.
From a setup perspective, Mailcow is touted for its straightforward deployment, often involving familiar tools like Docker Compose. However, some users note that initial setup can require several steps, including cloud server creation and DNS configuration, which might pose a challenge for less experienced users.
Feedback from Mailcow users is generally positive, emphasizing its ease of use and reliability. Many appreciate the platform as an all-in-one solution that integrates seamlessly with supplementary tools like anti-virus and anti-spam software. The built-in features, such as the separation of domain and user administration, are praised for enhancing management efficiency.
The platform is also commended for its commitment to sustainability. Its data centers, located in Germany, operate on 100% green electricity, a point that resonates well with environmentally conscious users.
Nevertheless, some critique Mailcow in specific areas. Sending email reliably can sometimes be challenging, with users occasionally experiencing issues that necessitate supplementary SMTP services. A notable workaround involves relaying through alternative SMTP providers to ensure email deliverability.
Within the broader landscape of self-hosted email solutions, Mailcow sets itself apart through its open-source model and active community. It provides an attractive option for those seeking to avoid the complexities of managing individual mail server components manually, a sentiment echoed by users transitioning from more traditional setups like Postfix and Dovecot.
Additionally, documentation like the Mailcow forum and GitHub repository fosters a supportive ecosystem. This resource availability is crucial for troubleshooting and optimizing users' mail server configurations.
In summary, Mailcow stands as a robust choice for organizations and individuals aiming to deploy a self-hosted email solution. Its Docker-based architecture, user-friendly interface, and active community support make it a viable option in a competitive field. While setup might require a learning curve, especially for those new to server management, the overall benefits and sustainable practices position Mailcow as a strong contender for those looking to self-host their email services.
