Which SMTP Port Should I Use? Learn Ports 25, 465, & 587 (and unofficial port 2525) | Mailgun

Posted by jpluimers on 2021/11/30

When trying to deliver mail, it is important to know which protocols and ports you can use.

On smtp, smtp-submission, smtps (ports 25, 587 and 465) and unofficial port 2525 (which Maingun maps to `smtp-submission): [Wayback] Which SMTP Port Should I Use? Learn Ports 25, 465, & 587 | Mailgun

Quote on why smtps port 465 is hardly used:

Port 465:

IANA has reassigned a new service to this port, and it should no longer be used for SMTP communications.

However, because it was once recognized by IANA as valid, there may be legacy systems that are only capable of using this connection method. Typically, you will use this port only if your application demands it. A quick Google search, and you’ll find many consumer Inbox Service Providers’ (ISPs) articles that suggest port 465 as the recommended setup. However, we do not recommend it, as it is not RFC compliant.

VFrontDe/ESXi-Customizer-PS: PowerCLI script that greatly simplifies and automates the process of creating fully patched and customized VMware ESXi installation images

Posted by jpluimers on 2021/11/30

On my list of things to try, as it allows me to have an ISO at hand in case I ever need to quickly re-install a machine to the current patch level (for instance when the USB boot stick breaks down: these things happen in reality): [Wayback] VFrontDe/ESXi-Customizer-PS: PowerCLI script that greatly simplifies and automates the process of creating fully patched and customized VMware ESXi installation images

ESXi-Customizer-PS is a Powershell script that greatly simplifies and automates the process of creating fully patched and customized ESXi 5.x and 6.x installation ISOs using the VMware PowerCLI ImageBuilder module/snapin.

Requirements

  • A Windows computer (XP or newer) with Powershell 2.0 or newer
  • VMware PowerCLI version 5.1 or newer

You can get the code from [Wayback] ESXi-Customizer-PS/ESXi-Customizer-PS.ps1 at master · VFrontDe/ESXi-Customizer-PS.

The old site (which still has most of the documentation) can be reached at two places:

A video showing how to use it is below the signature.

The above links via [Wayback] Custom ESXi ISO with ne1000 driver for install on Intel NUC Frost Canyon – seanwalsh.dev.

 

Oh: you can check if you have a PXE, USB or HDD installation of ESXi via the steps here: Determining the ESXi installation type (2014558) | VMware KB.

More on a failing USB stick later…
