  • Inviting everyone to the UX test of a new security feature in the WP Toolkit
    For WordPress site owners, threats posed by hackers are ever-present. Because of this, we are developing a new security feature for the WP Toolkit. If the topic of WordPress website security is relevant to you, we would be grateful if you could share your experience and help us test the usability of this feature. We invite you to join us for a 1-hour online session via Google Meet. Select a convenient meeting time with our friendly UX staff here.

Domainkeys and mail group

hgmichna

Basic Pleskian
Something ever computer science student learns pretty early is the concept of orthogonality. What is meant is that, if a computer program has two features, then it is not enough that one feature works and the other also works. The requirement is that both functions still work when they are both used at the same time.

I have meanwhile lost all trust in Plesk anyway, and they have no grasp of this concept either. My current example is the Domainkeys function and the mail group function. Needless to explain, Plesk neither programmed these two functions to work simultaneously, nor did they even test both of them together, otherwise they would have noticed that it doesn't work. The server happily rewrites the mail headers and doesn't care at all that this invalidates the domainkey.

Technically this is very simple to solve. When the server sends the mail to each recipient in the mail group, it has to write a new domainkey, just as it does for every other mail. Think for yourself about why Plesk still didn't do it.

If I look, I find a new defect every few days. The situation is totally hopeless.
