So it’s the good old client certificate authentication?

That’s what I do, too. My Dovecot is at home and I collect emails from all my accounts using fetchmail.

Nice thing is Dovecot Pidgeonhole for Sieve and Flatcurve for ultrafast indexing and search.

Yeah, haha. 😂

Wait a moment… 🤔

2 HDDs (mirrored zpool), 1 SATA SSD for cache, 32 GB RAM

First read: 120 MB/s

Read while fully cached (obviously in RAM): 4.7 GB/s

My Dovecot is still 2.3.21. It’s the most recent package. But you’re right the update doesn’t look trivial.

With an IMAP server you have the power to serve your own emails. fetchmail will deliver them constantly to this place. You have all emails in one place and you login just to your own server.

Basically what I said. Dovecot can be installed on every Linux or BSD system. You’ll need Pideonhole and FTS Flatcurve as extensions.

When you install fetchmail, you can let it connect to all your IMAP or POP3 servers. Each process will deliver your mail instantly to your own Dovecot server.

You’ll also need a certificate for Dovecot. This can be solved using Letsencrypt.

You can use any mail client you want. I use Fairemail on Android. On desktop and notebooks it’s Thunderbird.

I sync my emails using a Dovecot IMAP server on my home server. I fetch emails from all my accounts with fetchmail and sort them into the right folders using Sieve. They get indexed and are searchable (ultra fast!).

225000 emails in 13 GB (ZFS; uncompressed 18 GB).

This is an old PC (Intel i7 3770K) with 2 HDDs (16 TB) attached to onboard SATA3 controller, 16 GB RAM and 1 SSD (120 GB). Nothing special. And it’s quite busy because it’s my home server with a VM and containers.

The question is how do you get a bad performance with ZFS?

I just tried to read a large file and it gave me uncached 280 MB/s from two mirrored HDDs.

The fourth run (obviously cached) gave me over 3.8 GB/s.

There is nothing to refurbish in drives. They are just second hand devices. You can check if they are fine pretty easy and you need to take a look at the age (power on hours). I replace drives at 50k-60k hours, no matter if they are fine.

Most of these observations are subjective. I’ve had some Seagate drives that worked well but were very hot and wasted energy. On the other hand WD was crap so far, starting with 3 TB. Not because of quality, but because of power saving features that were a major annoyance to me (green and some blue drives). Red drives I had were mostly fine, even they wore out pretty quickly (Load_Cycle_Count bugs). They ran at 0% health left for a few years and had other awful SMART and on-drive controller bugs.

Since Seagate and WD are essentially the same company and they lied about SMR before, I wouldn’t buy either of them.
