Fedora Linux 43 exposes 20-year-old Microsoft Outlook security failure

https://fed.brid.gy/r/https://nerds.xyz/2026/06/fedora-43-outlook-security-bug/

During the proof-reading my proposal for monitoring a bunch of websites, I needed several times to replace the word POP3, which is the Post Office Protocol version 3 your mail client spoke in the late 2000's, with POP, which is a Point Of Presence in networking speak.

Brain memory, muscle memory and not looking at what I type...

2026年後半まで延長。「Gmail」POP3/Gmailifyサポート終了日程

Today at 1am I noticed that my mail server wasn't working well since 2 weeks and that lead to a fun quest about fixing it that took me a few hours.
I'm not working theses days as i'm starting a new job in 1 month so I had time to dig to fix it...

The visible symptom was that gmail wasn't able to fetch my mails via pop3.

First issue was that the debian trixie migration got me #dovecot 2.4 instead of the 2.3 that was there before and it's NOT a minor version bump, they essentially re-wrote a new configuration file format... And obviously my docker image didn't have a "dovecot -n" anywhere to check the configuration

The second issue was that gmail only goes to IPv6 if possible and that was broken too after a long search I didn't find why, but the default route wasn't obtained via dhcpv6, forcing it enabled and rebooting the VM solved that one.

If only I hadn't deleted the #POP3 connection in gmail, now it needs to download back the 40k emails of my inbox again and show me all the ones I deleted gmail side only 🤣

Besoin d’aide pour préparer une opération de #migration de boites #mails.

Là, j’en ai qui ont nettement plus de 20 ans et qui vont rechanger d’hébergeur, mais c’est surtout qu’elles sont toutes en #POP3 (option garde tout sur le serveur) et centralisées dans #Thunderbird (ouais, ça fait un maousse dossier sur mon SSD).

Là, va falloir passer tout ça en #IMAP avant la migration (chez @infomaniak_network) et la dernière fois que j’ai fait ça ( y a bien 10 ans), j’ai perdu tous mes mails.

So #Google (and #GMail by extension) are removing #GMailify for #POP3 imports.
Sure, no worries.

I've just downloaded and installed #Thunderbird
Not used this in years. Man, hasn't this app/software got so good over time?
Blown away...
