dovecot – out of the box setup

Matthew Heick Leave a comment

Trying to learn a new programming language is a daunting task. My process is to take programs that I’ve written before and rewrite them in the target language of choice.

I’ve got a PHP program that interacts with my IMAP server (smart-imap), reads all the messages in the Inbox, takes the localpart of the email address, creates a folder and moves that email into that folder. If the localpart is part of a pre-determined list of email addresses that have been sold off for Spam it’ll move it to the SPAM folder. If there are no localparts that match the domain name of the server then it drops it into an UNSORTED folder.

Today’s language of choice is Python, specifically 3.9.21. To do this entire feat without breaking things I need an IMAP server, and dovecot 2.3.16 is going to be the death of me.

Server Problems, 2025…

After Gettin’ hacked and rebuilding with a cheaper server I started encountering random slowness and problems. I always seemed to have random CPU spikes here and there but the console at digitalocean didn’t really give me much to work with.

Today I tried to install git so I can get some repos cloned down to demo and the process kept getting Killed. After some simple googling and basic cross referencing of the system I’m leasing I learned the stupidest thing in the world.

Gettin’ hacked…

This server got hacked. It was used as a scanner for a couple days, attempting to break into other servers to test for vulnerabilities. I only discovered this because I attempted to access this server by the .onion domain that I have for it and it didn’t connect.

I’ve had a home server hacked before due to a user account with a I set up for my son with “an easy” password. I thought I learned that lesson. Apparently I did not with the server I have exposed to the interwebs.

Time to forensically breakdown the timeline of events.

Today I Learned: Storage expensive, Data priceless

We have a combination Plex Media/Minecraft/Archive server that we’ve had since we purchased our first 6TB Hard Drive on December 30, 2019 ($99.99 at the time). After some time we upgraded to our massive 14TB Hard Drive ($293.00 at the time) on October 16, 2021. It took a bit over a couple years to fill things up, and now we recently invested into a 16TB Hard Drive ($279.00 at purchase) to continue our storage needs.

$ df -h
Filesystem      Size  Used Avail Use% Mounted on
/dev/sda3       457G  288G  169G  64% /
/dev/sda1      1014M  202M  813M  20% /boot
/dev/sdd1        13T   12T   52G 100% /mnt/usb14
/dev/sdc1       5.5T  4.3T  962G  82% /mnt/usb03

Now it’s time to get this new drive ready for usage.
