I have run my own mail server now for 20+ years. its is runnig postfix , with spamassain. the users have imaps, and roundcube www gui.
It had been running fine, and have been updated HW / OS a lot of time over the years, now its runnig on rocky O/S
If you are looking to do this then go check out Mail in A Box
Great collection and super helpful forums
Lol you could have read the post, he’s been doing that for 20+ years
I had read his post. There were plenty of other comments asking how/where and this makes it an easy option.

I watched a talk, “fun with email” by Dylan Beattie, and his personal advice was “dont bother self hosting unless you’re using it for contacting other self hosted users”.
Without the dedicated IT support and clout of a large company he said you’re gonna spend more time asking other servers to whitelist you than you’re gonna actually spend using your email.
Is that something you can corroborate?
That’s not true. I run my own email server for 15+ years now. There are only 5 of 6 mailboxes. I never had a problem with any other host. Not Microsoft, not Google. Maybe, the reason was, the IP was also 15+ years assigned to the same domain. I have only known senders, family and friends.
The last days, the hole subnet was blacklisted on some blacklists. So that was not my fault, the growing business of the provider lead to this situation. Eventually I moved to a very small provider and run a mail cow on a vps. On a fresh IP without any reputation. Same ‘customers’, the only issue was with T-Online in Germany, but a mail solved this. To keep this kind of issues away, I use sendgrid as a SMTP forward. With only a few mails per day, this is free. Mailcow provides a lot of features, rspam filtering, a lot better and faster than spamassin. Active sync, imap, webmail, everything. Solid backup, runs without any problem.
Fun with email was a great talk.
As someone who has zero experience hosting anything, what are the benefits of doing this?
Thank you!
Well I didn’t want google to read my mails, and use the content to generate ads, or profiles on me or my family. Besides that it’s keep me up to date on mailserver and mailman . Besides I do it professionally so it was easy
Well I didn’t want google to read my mails
Sadly, it only works if no one in the recipients of the mail is on gmail (or if everyone use pgp, which I would tend to think is even more rare).
I host my own mailserver as well, and I would add as benefits:
username+something@host). That also makes routing/filtering mails way more easy, you just have to match the recipient address.Thank you!
Now for the Final Challenge, write an eli5 tutorial on how to host and maintain a mail server!
I can’t take credit for writing it, but here you go!
I've been running a mail server for so long I used to understand Sendmail's M4 configuration language!
I am currently working on this. I got a static IP and port 25 unblocked from my isp. I am trying to do opensmtpd and dovecot with dkim signing.

I’m in a similar boat. The only major issue I’ve found people are likely to run into is mass IP blocks from MS/Google. Where do you host it? Cloud provider these days or colo type place?
Awesome, I’m only on year 3 or so. Have you implemented DANE? I haven’t gotten to a point where I can properly make it work but I’m slowly getting there.
Do you know if this setup could run on 512mb of RAM? I tried to set up mailman 3 but it gets OOM-killed immediately
You can, as long as you aren’t trying to do virus scanning - ClamAV needs a couple of GB on its own
Mines running postfix, spamassassin and dovecot and runs pretty happily in 1GB, but when I was running in 512MB Spamassassin would get killed fairly regularly when it ran out of RAM
Doubt it, but it’s the spamassasin part that I think won’t work.
Yeah, I’d recommend using rspamd for lower-end hardware over spamassassin. Might be a bit more work to set up, mostly because it’s not as popular, and there are fewer tutorials, but it doesn’t have the overhead from running on perl like spamassassin. That said, while there are people using rspamd on systems with 512MB of ram, they are usually smaller, personal setups that aren’t dealing with hundreds of emails a day.
Nope sorry, that is to little ram. I don’t know how much ram my mailserver uses but will look
Those that are hosting their own mail server, did you stop using regular mail (gmail, outlook etc). Is possible to migrate to self hosted mail? I don’t think I can’t stop using gmail and other google services that’s stopping me from trying to do this.
I’m am stopping using Google services, mail moved ( newer was there to begin with ) Contact moved Missing calendar, but it will be moved.
I’m de-googling my setup 😁

I’ve been told running an email server is the final boss of self-hosting
Im_old@lemmy.world 1 year ago
The ultimate boss fight is hosting your email server AND making your family use it
cooopsspace@infosec.pub 1 year ago
Actually to be fair, mine works fine and always has. The final boss is making Hotmail/live/Microsoft actually accept your email despite you jumping through all the hoops to have perfect spam score.
Appoxo@lemmy.dbzer0.com 1 year ago
Would never want to do it. I don’t wanna be responsible for the outage and them needing an important email.
ninjan@lemmy.mildgrim.com 1 year ago
IMHO, as someone running his own mail server, the real final boss is LDAP and implementing SSO on all your selfhosted goodies. Bonus points if you then use it to login to other services that support OAuth 2.0.
Slotos@feddit.nl 1 year ago
Did you mean OpenID perchance? OAuth is not an authentication protocol.

I have my own mailserver just for me and it wasn’t that complicated to be honest. I set it up with Mailcow in Docker in under a day so far it has been stable with regular backups and updates through Lighthouse.
Maintenance comes down to 5 minutes every three months because somehow Let’s Encrypt and Mailcow don’t like each other and I have to renew the certificate manually.
