I configured my Azure SQL Database to allow connections from the VNet.

System or critical user never log in
mx flag

Besides Exchange, does AD itself, or other well known apps create user objects but never use it for login? I am trying to clean up inactive accounts and don't want to remove something that appears unused but actually important. Specifically, is it safe to remove any account whose lastlogonstamp is NULL (so it's never logged in) but was created long time ago (again, excluding Exchange objects)?

I am familiar with how to configure Postfix via its master.cf/main.cf files; the answer to my question on Debian (which is what I'm familiar with) would be to set mailbox_command = <path to mta> in main.cf.

On openSUSE, which I am recently using for the first time, it appears the "native" way to configure Postfix is via /etc/sysconfig/postfix and then running /usr/sbin/config.postfix, which t ...

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.
