I don't understand. Dovecot refuses to issue the correct SSL cert. I've checked and triple checked the file name in /etc/dovecot/conf.d/10-ssl.conf. I've restarted the service multiple times and even rebooted.

Apache issues the correct cert. They are using the exact same files.

perplexing.

CLI command to check dovecot:
openssl s_client -connect mail.heerssen.net:465

And Apache
openssl s_client -connect mail.heerssen.net:443

Grr. The SSL certs for my primary email domain expired, so I renewed them.

WHY ISN'T IT WORKING?

Because you didn't restart dovecot, you idiot.

I am experiencing burnout solely because of trying to configure S3 in my Pixelfed admin panel, and I am a noob at S3 configuration. It feels like I don't know what to say to the panel, even though I have already paid for the object storage credits, and it is charging me hourly even though I don't have a bucket. I wish there were magic; I wish somebody could help me.

Server Admins:

There is an error with the latest #Plesk Obsidian update that is taking sites down.

Welp, my mastodon server is being wonky. It displayed the error page for a while, so I rebooted. The server failed to boot twice, then booted normally on the third attempt. I think there are two issues.

First, upgrading Ubuntu from 22.04 to 24.04 seems to have caused some sort of initramfs issue on the VPS.

Second, the Mastodon upgrade to v4.4.1 had a lot of problems and had to be restarted several times. That may have introduced some errors.

Finally got my Mastodon server upgraded to 4.4!

It looks like quote posts are working, too.

so fixed my mastodon install lol

The domain name for this instance was just transferred away from squarespace to Namecheap. I think I have everything configured correctly, but we'll see. If I disappear, that's what happened. :P

And with that, I'm done with Squarespace for good.

Playing with email again. Since I have an email server and a mastodon server, I figured why not have an email address for my mastodon account. So I did. If you want to email me (and I don't know why you would) you can now send mail to my mastodon handle, omitting the leading @.

I might come to regret this.

I just transferred the darkmoon.social domain away from Squarespace, so this instance may go down for a short time before I can get DNS set up again. If that happens, don't be alarmed. It'll be back up in all of its radiant darkness soon.

Question for postfix folks:

I have a Postfix instance handling two virtual domains on a VPS, and both currently share the same ipv4 and ipv6 addresses. I would like to properly configure dmarc, but that requires separate IP addresses for each domain. My provider is loathe to give me a second ipv4 address, claiming scarcity. Fair enough. They did provide an ipv6 range that I can use.

So, are there still issues with ditching ipv4 altogether for at least one of the domains?

Well, this blows. Spamhaus has blocked the entire 2600:3c00::/64 IPv6 range, which includes my email server. That seems a little excessive.

I found out because I tried to send an email to my employer, and they use Spamhaus. This is a problem for me and I'm not sure what to do. Maybe I can disable IPv6 for sending email. I dunno.

I finally got my first bit of legitimate spam (is that even a thing?) since installing SpamAssassin on my mail server. SpamAssissin did its job and correctly tagged the message as spam.

Honestly, when I first set up my mail server, I thought I'd get a lot more spam. Either I've been lucky, or my internet hygiene is pretty okay.

Woohoo! I got spamassassin working. Now to wait for some more spam. I never thought that would be something I'd write.

Did the admin of the server where my site is hosted today. Keeping AI scrapers and AI bots out is ongoing and successful.
A thing that has been a trend for a while now, is the increase in visitors with a VPN. Okay, it makes studying demographics harder, but it makes me a happy man. More and more people see the light about being safe and anonymous on the internet.

Yikes! I almost forgot a very important step.

I recently added email to my mastodon instance, and with that success, I'm ready to finally cut email ties with Google. I bought a new domain name and I'll set that up with postfix/dovecot/etc, then start moving all of my various internet accounts over to it.

The new domain has a .net TLD instead of the current .com TLD, and that's nice; it's more appropriate since I'm not running a business. Now I'm just waiting for the DNS changes to propagate.

Hey guys, I have a question for anyone out there who likes to #selfhost

I'm looking for inspiration and ideas for new services to host on my Ubuntu Server instance. I have Pihole running, and I'm wondering what you guys who run Ubuntu Server in your #homelab have running in your servers?

I'm new to all of this, so please be kind, as I said before, I'm just looking for inspiration!

Upgraded to Mastodon v4.3.6 https://github.com/mastodon/mastodon/releases/tag/v4.3.6 - let me know if there are any issues.
