Hey, if anyone wants an ARC of the new novel, we're coming up to the end of sign-ups: tinyurl.com/LHftWarc

Google DocsLazarus, Home from the War ARC Sign-Up FormIt's Good? to be Home Lazarus Lenkov has been a civilian for almost two months, and it's going great. Sure, he's working at an art gallery instead of flying planes. Sure, his brother is preoccupied with his new husband, his sister is busy with her new baby, and he's plagued by nightmares and his malfunctioning foresight. But there are good things, too. He's got a new car. And just today, he got hit over the head with a bottle and then stitched up by a cute neurologist. Who then rejected his advances, but you can't have everything. Eli Sobel has never met anyone quite like Laz. He's smart and handsome in a scruffy way. He's also a mess. From the first time they meet, it's clear that Laz needs someone to take care of him, even heal him. And while Eli's a doctor, he's not interested in taking on any patients in his personal life. But Laz is funny and generous, and Eli can't help but get drawn into the investigation surrounding the attack he stitched the man up from. There's bad magic afoot, though neither of them quite understands it. From a similar crime at a Minneapolis art gallery to dead bodies in Edina, Minnesota, each step of the inquiry seems to pull the two of them closer together. But when they finally uncover the surprising motives that tie the events together, will they be able to move past their history into an uncertain future together?

@grumpybozo : I definitely am not angry with you (I very much agree).

Unfortunately many admins treat security solutions like they're a religion.

Some time age there was a hefty debate on a Dutch "mostly admins" site (tweakers.net, I'd have to look up the exact thread) about the "correct" sending and receiving MTA configurations. There was no agreement.

Microsoft even used to ignore SPF/DKIM/DMARC if the sender was in the "safe senders" list (which the user's address book defaults to). What could possibly go wrong (later MS corrected that).

The screenshot below is from part of security.nl/posting/766069/DMA (I wrote that Sept. 14, 2022).

Screenshot from part of https://www.security.nl/posting/766069/DMARC+bypass+%28Outlook+only%3F%29#posting767981 Microsoft has meanwhile changed this behavior, but https://docs.microsoft.com/en-gb/microsoft-365/security/office-365-security/use-dmarc-to-validate-email#how-microsoft-365-handles-inbound-email-that-fails-dmarc used to read: { How Microsoft 365 handles inbound email that fails DMARC If the DMARC policy of the sending server is p=reject, Exchange Online Protection (EOP) marks the message as spoof instead of rejecting it. In other words, for inbound email, Microsoft 365 treats p=reject and p=quarantine the same way. [...] Microsoft 365 is configured like this because some legitimate email may fail DMARC. For example, a message might fail DMARC if it's sent to a mailing list that then relays the message to all list participants. If Microsoft 365 rejected these messages, people could lose legitimate email and have no way to retrieve it. Instead, these messages will still fail DMARC but they'll be marked as spam and not rejected. If desired, users can still get these messages in their inbox through these methods: • Users add safe senders individually by using their email client. [...] }

It does not even do that on my iPhone.

P.S. SPF was invented to prevent Joe Jobs (en.wikipedia.org/wiki/Joe_job). Marketing idiots (including Bill Gates) said that it would kill spam. It killed forwarding instead.

The Triumphal Arch Of The Carousel

"The Arc de Triomphe du Carrousel was built by Percier and Fontaine in circa 1806 to 1808 to celebrate the Napoleonic victories of 1805, and it was originally intended as a monumental entrance to the Tuileries palace."

The image showcases a striking architectural scene centered around the Arc de Triomphe du Carrousel, a magnificent triumphal arch. The arch is intricately adorned with detailed sculptures and reliefs, reflecting a rich history and artistry. Above, a chariot is depicted, pulled by horses, symbolizing victory and grandeur. Surrounding the arch, the environment exudes a serene ambiance, perhaps suggesting a moment frozen in time. The contrast of light and shadow, accentuated by the black-and-white treatment, adds a dramatic flair, enhancing the elegance of the structure. In the background, the Louvre’s distinct architecture looms, further contextualizing the arch's historical significance. Visitors appear small beneath the towering arch, emphasizing its monumental scale. This invites reflection on themes of time, history, and coming together in a space that has witnessed countless events and societal changes. The atmosphere invites curiosity about the stories held within its walls, evoking a sense of nostalgia and reverence for the past.
