mail.com (handled by gmx.com) can reject SMTP connections as early as in the EHLO stage
Posted by jpluimers on 2020/04/06
I found this in one of my logs a a while ago:
Error when executing EHLO command for domain mail.com on SMTP server mx00.mail.com.
(554, 'mail.com (mxgmxus007) Nemesis ESMTP Service not available\nNo SMTP service\nBad DNS PTR resource record.\nFor explanation visit http://postmaster.gmx.com/en/error-messages?ip=37.153.243.242&c=rdns')
It means that gmx.de / mail.com are among the strictest email handling providers I know. I don’t blame them: EHLO is at the start of an extended SMTP session.
At [WayBack] Error messages | GMX Postmaster it indicates:
5xy Bad DNS PTR resource record
Emails from your email server were rejected because the PTR Resource Record (PTR-RR) of your IP address does not follow our guidelines. Possible reasons for this can be:

xrdp
Posted by jpluimers on 2020/04/06
I totally missed this the last 5 years. Where have I been (:
[WayBack] xrdp: An open source remote desktop protocol(rdp) server.
It runs on top of either Xvnc (which I have used) or X11rdp and should be usable with any RDP client (like the excellent Microsoft RDP for Mac OS X).

Some links that should me help shrinking the virtual disk files of Windows VMs
Posted by jpluimers on 2020/04/03
With virtual disks, at least these three levels are involved:
- partition or volume (often called drive) size
- virtual disk size
- virtual disk backing store size
When talking about shrinking disks, they usually explain about below steps, assuming there is a 1:1:1 mapping of the above and backing store of the disk is dynamically growing:
- defragment the files on a partition/volume
- zero-fill the non-used space
- shrink the virtual disk assuming it is a dynamically growing one
For various reasons, virtualisation environments can have pre-allocated virtual disks ensuring the space on the backing store is firmly reserved.
One such occasion can be in VMware (often required for instance with vSphere/ESXi/ESX based infrastructure, but can also be used in Workstation/Fusion/Player) or Virtual Box in fixed disk mode (default there is dynamic).
Here are some links that should me help shrink in those situations:
- Shrinking inside Windows 7 and up is easy with Disk Management (but be aware that NTFS cannot shrink below a certain size which is usually half the size your started with; I need to find links that back this up): [WayBack] Easily Shrink a Volume on a Windows 7 Disk
- VirtualBox has a great VBoxManage tool (both on Windows and Linux/MacOSX) with lots of virtual disk conversion options that are somewhat under-documented:
- [Archive.is] virtualbox.org • View topic – Question about –variant options (clonehd)
Note to self: VMware Workstation/Player/Fusion is happy with--variant Standardbut ESX/ESXi/vSphere requires--variant Fixed,ESX(see [WayBack] Import VirtualBox VMs in VMware ESXi) - VDI might be an easier route than VMDK: [WayBack] How to resize a VirtualBox vmdk file – Stack Overflow and the very similar [WayBack] How to resize a VirtualBox .vmdk file on MacOS – Vuong Tran – Medium

- For dynamically allocated disks only: [WayBack] Compacting VirtualBox Disk Images – Windows Guests (tips on SDelete and ZeroFree are at[WayBack] How to Shrink a VirtualBox Virtual Machine and Free Up Disk Space)
- VMware has a virtual disk split over 2 files: a text file describing the disk and a binary file with the actual disk content, so if you know you are doing you can modify the description, then migrate to other storage to shrink the binary [WayBack] Shrink a VMware Virtual Machine Disk (VMDK) – virtualman via [WayBack] Best way to shrink a VMDK file (D Drive) of a VM ? |VMware Communities even though [WayBack] Growing, thinning, and shrinking virtual disks for VMware ESX and ESXi (1002019) tells it is not possible.
- For dynamically allocated disks, VMware Workstation 5 and up can do it as well: [WayBack] Shrinking Virtual Disks
- [WayBack] How to Shrink a Hyper-V Virtual Disk (VHD and VHDX)
- Paragon Hard Disk Manager (HDM) can migrate NTFS partitions from one disk to another, so you can create a smaller virtual disk, then migrate to that.

PS: a useful tip by Joe C. Hecht on shrinking:
Oh… On shrinking VM Disks, I make a new growable disk, then use a utility to “smart copy” the partions to the new disk (then replace the disk files in the VM). The “smart copy” just copies the file system – IE what is used (I use an old copy of Paragon Hard Drive Manager). It works out a lot better than writing “zeros”. I then make a compressed image of the whole VM using rar5 compression with a 1GB dictionary size. I then have batch files that can unrar the VM’s on a moments notice (from a collection of over 300).

According to [WayBack] Hightlight active row/column in Excel without using VBA? – Stack Overflow: no, but you do not need much code.
On my list of things to try is to combine both answers there into one.
