I don&rsquo;t know what to say about what&rsquo;s happening in the US, but I know I can&rsquo;t stay silent, either. I don&rsquo;t have anything inspiring to say here. I just cannot keep silent and pretend it&rsquo;s all business as usual.

It is possible to send any type of data using MQTT including files,images and video. However MQTT wasn’t designed for file sending but for sending small data packets from remote sensors. Having said that the actual maximum message size is very large (256MB). However not all MQTT brokers will support the maximum packet size and all public brokers have message size restrictions often between 128KB…

## [Folding email headers](https://www.wordtothewise.com/2025/11/folding-email-headers/)

_2025-11-21 · Word to the Wise_

Why are my DKIM signatures failing at Microsoft? There are several reasons why your DKIM signatures might be failing at Microsoft, but perhaps not at other major providers. Many of them are triggered by sending mail that&rsquo;s &ldquo;badly structured&rdquo; in some way. This is one of them.

I cannot count the number of times I hear someone complain that they didn&rsquo;t change anything and now their email isn&rsquo;t delivering and why did this happen all of a sudden and how can they be blocked now when they weren&rsquo;t blocked 3 months ago. Nothing changed, so why all of a sudden is mail failing?

## [Deliverability rules](https://www.wordtothewise.com/2025/08/deliverability-rules/)

_2025-08-18 · Word to the Wise_

Hot Take: Anyone who has to know exactly what the rules are for inbox delivery is trying to figure out how close they can get to violating the rules without negative consequences. Senders that comply with the spirit of the rules don&rsquo;t care what the specifics of the rules are.
