TL;DR Fast and easy way to copy postfix/dovecot/imapsync configuration to new pc?

First of all, I almost have no clue on how email and email servers work.

Moving on, I have an old server with an old broken ubuntu installation without GUI. I bought a new pc to replace it. I tried a mad shot by replacing the hard drive in the new PC with the one from the old one, remotely hoping it would boot and upda ...

new kernel and exfatprogs do not support same mount options as exfat-utils
my flag

On multiple machines at work and at home, I multiboot between one or two flavors of Linux and a few flavors of Windows. In order to keep my data centralized regardless of what OS I'm in, I use an exFAT partition; in Linux, I mount it on startup in /etc/fstab.

Using default mount options in /etc/fstab results in the contents of the mount having root:root ownership - which isn't a deal-breaker, but ...

The Stunning Power of Questions

Much of an executive’s workday is spent asking others for information—requesting status updates from a team leader, for example, or questioning a counterpart in a tense negotiation. Yet unlike professionals such as litigators, journalists, and doctors, who are taught how to ask questions as an essential part of their training, few executives think of questioning as a skill that can be honed—or consider how their own answers to questions could make conversations more productive.

That’s a missed opportunity. Questioning is a uniquely powerful tool for unlocking value in organizations: It spurs learning and the exchange of ideas, it fuels innovation and performance improvement, it builds rapport and trust among team members. And it can mitigate business risk by uncovering unforeseen pitfalls and hazards.

For some people, questioning comes easily. Their natural inquisitiveness, emotional intelligence, and ability to read people put the ideal question on the tip of their tongue. But most of us don’t ask enough questions, nor do we pose our inquiries in an optimal way.

The good news is that by asking questions, we naturally improve our emotional intelligence, which in turn makes us better questioners—a virtuous cycle. In this article, we draw on insights from behavioral science research to explore how the way we frame questions and choose to answer our counterparts can influence the outcome of conversations. We offer guidance for choosing the best type, tone, sequence, and framing of questions and for deciding what and how much information to share to reap the most benefit from our interactions, not just for ourselves but for our organizations.
