What Happens If You Alias An Entire Domain in Postfix Email Server?
This doesn't come up often, and the issue with that is that few people know what will happen when you do this.
So the question is what actually happens if you add something like...
@myemaildomain.com [email protected]
Into Postfix's alias file? Well, it's pretty simple, but not necessarily easy to track down. This is a domain alias and from my testing, the order of precedence is not what we would expect. And that makes all of the different here.
First, we need to understand that the alias file is actions before the mailbox file (it has to be, if you think about it.) So if the alias file hijacks something in the mailbox file, the mailbox rules never get touched. That's critical because it is easy to look in your mailbox and feel that things are configured for local delivery, and with no per-user alias in the alias file, we might think that things will still go there.
Second, in the alias file the individual aliases are actioned before the domain alias. This is good, but ultimately confusing if you test an email in the domain and it works, but has an alias, it will also potentially lead you down a rabbit hole of troubleshooting that you don't want to do. So if you make an alias for an individual user, that will work normally, and only once individual account aliases are actioned is the domain alias actioned. Ultimately this makes sense as a mechanism if you think about it, but it is not really what we would expect if only approaching this casually.
So what we find is that a domain alias will not affect individual aliases, but will effectively disable all mailbox configurations for the domain in question. A powerful tool, but one you want to use carefully as the results are often not what people are thinking that they wanted to do.

RE: What are you using to open HEIC files?
@PhlipElder said in What are you using to open HEIC files?:
@WrCombs said in What are you using to open HEIC files?:
Subject is the question, what are you using if anything to open HEIC files (video files) on Windows 11 ? I get videos from customers showing me problems and sometimes they come through like this, Usually can't open them.
Was using the freebie OEM extensions from the Microsoft Store but those are now gone.
I'm not going to pay $1.40 for something that should be free.
So, flipped the iPhone to Compatibility Mode (JPG).
Advantage to HEIC is HDR, and smaller file sizes. But HDR is the big winner. Most people don't care, but in case you were wondering what you might be giving up.

@scottalanmiller your emails from the forum started showing up in inbox again. That is at least why I returned
They disabled randomly at some point.
Welcome back!

I think that we are back on the Google good graces or something. Volume is definitely up.

RE: What Are You Doing Right Now
Just had a user, who never once posted anything, come in and after EIGHT years, and ask for their account to be disabled. Which since it is an unused account is pretty easy to do. But, weird. Who makes an account, and then EIGHT years later comes back searching for it, finds it unused and pointless (and remember, anonymous) and wants to go through the effort of deleting it? The weird things that happen on forums.

Since making the changes to block spam, the spam accounts seem to have gotten SO much worse. We've never gotten so many before.

If they are videos, that means HEVC which is just h.265 and everything (except Windows native) reads that, it's the native format of even GoPros and Insta360 and DJI stuff. Like EVERYONE uses it for non-pro work (PRO work is nearly all done in ProRes.) So just VLC for that.

Neither is Windows. jajajaja

VLC media player doesn't work
That's for video. Will work for h.265, but not HEIC.

GIMP seems to be the winner; anyone use GIMP a whole bunch?
Used to, but I'm not a photo EDITOR, only a photo taker. So no need to edit the files these days for me and if I was to, it would be to tweak not draw, so DarkTable would be my go to.

How To Unblock Files on Windows That Are Blocked with PowerShell
Sometimes Windows will detect that a file has come from another computer and will block the file. Unblocking a single file from the GUI is super easy. It's just a check box. But if you have lots of files, this is tedious. Even if you set Group Policy or the Registry to stop blocking any files, ones that are already blocked remain blocked. What to do?
PowerShell is here for you. Just use a recursive DIR command and pipe the output to the Unblock-File commandlet and voila.
dir c:\mydata -Recurse | Unblock-File

RE: Choosing between Microsoft Hyper-V 2022 and VMware vSphere 8.0?
@Oksana easy, choose neither. For years the good choices are KVM and Xen. Hyper-V is all but abandoned and Vmware is the trailer of the pack.
