Mailu Reviews

20+ Options for hosting our own mail server
Mailu To be frank, this one I liked very much. It can be easy as to run 3 to 5 commands if you docker and docker-compose installed already. As you might have noticed, above link to mailu itself is pointing to the docs. Go get it. Github issues is a best place, if you are stuck at something Mailu Issues. From my personal experience and as per docs, atleast 2GB of RAM is...

  • Has anyone setup a Linux based internal only smtp relay?
    I've had something of the same experience with Postfix, u/0x29aNull. Check out OpenSMTPD. It is lightweight and standards compliant. I know that there are packages for Debian and Alpine Linux. There may also be ones for Fedora/RHEL derivatives. I use it in my environment on OpenBSD. Source: over 1 year ago
  • DKIM Migration: Rpamd instead of DKIMproxy out on OpenBSD / OpenSMTPD
    When I installed Rspamd with on OpenBSD / OpenSMTPD the other day, DKIMProxy out (dkimproxy_out daemon), which had been got via OpenBSD Ports package system, was used to add DKIM signatures to mails in order to improve security on emails. - Source: dev.to / almost 3 years ago

  • Email Hosting for 100+ mailboxes with 200GB storage
    Self hosted: I use https://mailu.io/2.0/ and it's awesome because it's easy to install and back up, it's lightweight and has all the features I need in a self hosted email solution. I don't send emails directly from my server though because of deliverability issues. Instead I use https://www.zoho.com/zeptomail/ as SMTP relay in Mailu to send emails so I never have to worry about deliverability. Mailu is free and... Source: 7 months ago
  • Domains and Email hosting
    I just used Mailu[https://mailu.io/2.0/] to setup my email server last week for my domain configured with cloudflare too. It took a while, but I was able to configure it successfully. Source: 12 months ago
  • should i get 1 or 2 Homeservers
    I thought about using this docker container for email https://mailu.io/2.0/ , I think most of the work is already done there. Source: about 1 year ago
  • How to create my own SMTP Server with my own domain?
    You can use Mailu it's a FOSS and it's pretty much straightforward because it runs on docker. Source: about 1 year ago
  • Maddy: Composable all-in-one mail server
    I see no one has mentioned Mailu (https://mailu.io/1.7/). It’s a self hosted mail server made up of a couple docker images. I would recommend it based on my use and experience. I’ve been using it for my personal email and for automated no-reply messages in a few projects with no delivery issues. It handles spam with rspamd, sets you up with DMARC, DKIM, has an admin interface, web mail interface. - Source: Hacker News / about 3 years ago
