comment How Is It Possible To Send Email Under Our Domain Name
@Martijn The choice of respecting SPF or not is at the receivers end. Nothing can be done if the reciever wants to receive spam ... (Then again, there are scenarios that make SPF implementaion slightly nontrivial, such as internal redirects and backup mailservers: One has to make sure that only the first receiving MTA chekcs SPF)

Just because it runs through cables (among others), doesn't make it an electric protocol either

@user1603548 No, if your file names are as listed in the question and should be modified as listed in the question, then this one line command will perform the renaming exactly as desired.

comment Windows (partially) claims I have a private key for a foreign certificate
@harrymc Well, it looks as if the very same API is responsible for both results (at least it is the very same dialog window ...)

comment Windows (partially) claims I have a private key for a foreign certificate
@Ramhound The certificate is not self-signed, it is signed by Thawte. Why is it normal tha a dialog says that I do have the private key for a certificate - when I don't (and another equivalent dialog says that I don't)? If I really had the private key, I cold use it to sign as someone else, which I obviously shouldn't be able to (and indeed the attempt fails - so this is really raher an annoying display problem, but what's behind it?)

comment Windows certificate manager restore private key somehow
It's not soo much of a bug and inded a feature. You need your private key even when the corresponding public certificate has been deleted or made invalid or it has expired. For example, otherwise you couldn't decrypt any data encrypted via the certificate. A certificate is to be viewed as something totally separated from a private key (for example you collect many certificates of thirs parties, of course without their private key). - Installinmg one's private key on a foreign machine, that is the real security gap (even if you deleted it, his box might long have copied it in the background).

comment Intercept and modify print jobs
@BenjiWiebe Hm, you mean print ot PDF, let my script manipulate the PDF, then print the modified PDF? Might be worth a thought (and a try) ...

comment Intercept and modify print jobs
@BenjiWiebe As far as I know PDLs, it is much more efficient to transfer a font description and then transmit the text content (which glyph of which font should be placed where) to the printer than to do the raster-image-processing on your computer and transmit the (resolution-dependant) image data to the printer. So, no, I assume I could get along withoput OCR.

comment Query site for given ip from AD sites and services
Thanks. This was not precisely what I was looking for (or my question was not clear enough), but with this as a starting point I now found nltest /DSADDRESSTOSITE: ipaddress and DsAddressToSiteNames()
