New post on how to filter out email using GNU Mailutils sieve command. It's great for organising email so that you can focus on the important ones!

Sieve's actually a standard. I thought you had to run a full Dovecot IMAP server to use it - overkill for filtering email! Turns out that Mailutils has a command line Sieve that can run after mbsync!

Also, a detailed page on Sieve:

@riff Le pire, c'est que je fetche déjà automatiquement les mails de toutes mois plusieurs fois par jours avec #mbsync, à des fins de sauvegarde.

Mais c'est que le quart du boulot, quoi.

I wrote a new blog post about how to setup #neomutt #email with Office 365, using #mbsync #msmtp and #notmuch, along with how to make it work with multiple accounts:

Decided to take the plunge today and finally set up @nixos_org secrets management with #sopsnix, so that I could set up declarative email, calendars, and contacts in #nix home manager using #vdirsyncer, #khal, #khard, #mbsync, #notmuch, and #aerc. The documentation still isn't good enough, so I had to dive into the source nix files for the various home-manager options, but it wasn't too bad, and it was fun!

@florine I just created a free trial account, and don't have much to add apart from that receiving mail works just fine, and I was able to get IMAP access to it setup and working with #mbsync and #notmuch without any trouble at all. As others have said, can't test sending mail from it as trial only allows you to send to mailbox.org accounts. I doubt that'll be an issue though.

Will explore Android clients tomorrow...

#degoogle

For quite some time I have sporadically run #mbsync configured to pull several IMAP accounts and it indeed brings in emails. BUT:

- #maildir format is weird. What's with the cur/new/tmp structure?
- why the heck is the hostname in the filenames?
- Feels like it doesn't like to be migrated and be continued from somewhere else.
- two-way sync seems to be kinda broken (not needed anyway)
- Holy cow is the configuration unnecessarily verbose and complicated 🤯 (should be well #nix-able though)

@parleur c'est quoi #mbsync ?

Bon, et c'est parti pour une reconfiguration de #mbsync pour une bonne douzaine de boîtes mail, parce-que c'est quand-même top au moins pour l'archivage.

I started my own fork of #isync (or #mbsync)

https://codeberg.org/jarkko/isync

It has now couple of commits:

I plan to do this for all of those, as it allows to cut some slack out from bit_enum_get.pl. That will lead to a roadmap where eventually the whole ugly script can be rendered out replaced with BIT_UL macro from kernel (msync is GPL 2.0 licensed).

There is also a #zig branch but before build can be defined properly the C codebase first needs to be made sound in terms of the build. Then it is relatively easy task to repeal and replace main.c with main.zig.

Here’s my #mbsync #GCC workaround for #Fedora:

commit ebf6bcea7ebdba15553692777d292e59ec1d5e2e (HEAD -> master)
Author: Jarkko Sakkinen <jarkko@kernel.org>

    work around a GCC-14 optimizer issue
    
    mbsync throws SIGSEGV in sync_opened(). As it turns out for some
    reason the second entry in the local array 'boxes' is optimized
    out:
    
    (gdb) print boxes
    $1 = {0x5555556c4540, <optimized out>}
    
    Fix this by pinning the variable using a dummy inline assembly
    statement:
    
    __asm__ __volatile__("" :: "m" (boxes));
    
    This sets an invariant, which should guarantee that the compiler
    leaves 'boxes' untouched.
    
    As a comparative measure mbsync was compiled also with clang without the
    fix, and the resulting ELF binary does not have this issue.

I found a modern actively updated alternative for #isync (or #mbsync): #m2sync

It is part of #vomit project: https://sr.ht/~bitfehler/vomit/

Compared to the complexity of ~/.mbsyncrc, my config is now dead simple:

cat .config/vomit/config.toml 
[kapsi]
local = "~/.cache/mail/kapsi"
remote = "mail.kapsi.fi:993"
user = "jjs"
pass-cmd = "pass show imap/mail.kapsi.fi"

I love vomit!

#homelab What didn't go as well:
- Needed flatpaks & appimages for more recent versions than in #leap but I'll live. I'm not ready for #tumbleweed for a daily driver.
- Using the Vorta GUI for Borg backup under sudo. Kludged it with waypipe.
- offlineimap (python2). There's a Py3 version but it was a no go even trying to use the git repo. Switched to #mbsync.
- Fighting the firewall. Default on. Pulled my hair out for a while with mDNS etc.
- atuin uses sqlite3 which behaves badly on ZFS.

Spass: #mbsync synct alle Mailboxen. Beim nächsten Aufruf beschwert es sich. dasdie Foldertiefe zu hoch ist (vuiele Folder in der Hiearchie).... und will nimmer ;)

After a lot of other stuff I’m back at it. TIL that php ENUMS are kind of hard to do assertions on in PHPUnit. assertSame and assertEquals both don’t work.

What I can do though is this:

$this->assertSame(SyncStatus::Pending->value, $syncStatusAfter->value);

#buildinpublic #mbsync
