Next Domino Events near you: DominoHUB (Tokyo/Japan) and DACHNUG in (Vienna/Austria)
17 June 2025
Thomas Hampel
Busy days ahead with two conferences on (almost) opposite time zones.
See me next week in Tokyo (Japan) and the week after in Vienna (Austria)
1. DominoHUB - The premiere event for Japan
With this years event theme "#DX (Domino Experience) - The Truth About Domino” the conference will be held in Tokyo to delve deeper into the latest information and usage of HCL Notes/Domino.
The power and potential of Domino will be introduced with actual case studies, and the latest technology trends will be explained.
This is a great opportunity to learn the truth about Domino and accelerate your business DX!
19. + 20. June 2025
https://www.dominohub.net/
I'm going to present on our new features in Domino 14.5 together with my colleague Matsuura-san
2. DACHNUG - Expert knowledge, networking & a unique supporting program
DACHNUG is far more than just a classic specialist conference ‐ it is the central meeting place for the German-speaking Notes/Domino and HCL software community.
This is where experts, decision-makers and users come together to exchange ideas, learn from each other and make valuable contacts.
23.-25.June.2025 ‐ Vienna / Austria
https://dnug.de/en/dachnug/
At this conference, you can find me in several sessions:
(1.) Carsten Jenn (TimeToAct) and me will host a workshop about Domino IQ,
(2.) Wannes Rams (ISW) and me will talk about Sovereign Cloud (a very hot topic these days!)
of course I'll be presenting (3.) the Domino Roadmap on Wednesday and finally will do a deep dive on (4.) Domino IQ together with Daniel Nashed
Safe Travels & See you soon !

Microsoft requires DMARC for consumer domains and what it means for you
6 April 2025
Thomas Hampel
These days a number of customers are reaching out to us due to Microsoft's announcement to make DMARC mandatory.
Customers are afraid of their mails getting lost because Domino does not provide native DMARC support yet.
For outbound mails, DMARC just describes what a recipient server should do with an email.
By using a DNS TXT record in YOUR DNS, the recipient is instructued to do: Nothing, Quarantine, or Reject an email from a sender that does not meet your SPF record and doesnt provide a DKIM signature.
Sounds easy (+is easy) for Domino customers to set up - details at the end of this post
How will Microsoft's announcement affect you?
Let's take a look at the facts first:
- Microsoft's announcement will affect CONSUMER domains (=hotmail.com, live.com, outlook.com), but not other domains.
- Even after May 5th 2025, Microsoft will not reject your mails.
- Non compliant high volume senders (to consumer domains!) will find mails ending up in the junk folder of the recipient.
- A typical O365/Exchange Onprem customer using @YourDomain.com is not affected, for clarification see this official comment from Microsoft
This all is nothing new. Google also announced the same same, and it is in effect since February 1, 2024
Are you sending more than 5.000 mails PER DAY to @hotmail.com, @live.com, or @outlook.com or likewise for @gmail or @googlemail.com accounts?
Then you are a considered being a bulk sender!
Bulk messages often are marketing campaigns, targeting individuals only using generic MS or Google domains listed above. Essentially being B2C mailings.
You can still send mails to folks using those email domains. Just if your company sends more than 5.000 mails in a single day your mail might be put into the Junk folder if you have not added a DMARC record.
By the way, for marketing initiatives, mass mailings, etc, take a look at products like HCL Unica
However, if you want Domino to meet the DMARC requirements, all you have to do is to enable DMARC in DNS.
A prerequisite is having configured SPF and DKIM, both are standards Domino supports.
With those prerequisites being configured, enabling DMARC is quite simple.
For details see step by step instructions in this article and once done, run a DMARC check against your domain.
If you are looking for a Domino application to analyze DMARC Inbound reports, take a look at this template from NTF-Factory
As a side note:
Microsoft Exchange (onprem) does neither support DKIM nor DMARC - both would require 3rd party products (see this).

Balkonsolar - year two in review
2 January 2025
Thomas Hampel
It's been two years ago when I installed two solar panels on my balcony to produce my own power.
I've already blogged about it at length last year.
Now another year has passed and I'd like to review it again because some parameters have changed.
1. The cost of power per kW has reduced from € 0,49 to € 0,35 per kWh
2. Panels are now positioned at an angle instead of just hanging at 90degrees
3. New solar panels are cheaper than ever before.
so lets take a look 2024.
I've done a first assessment exactly one year ago, so now its time to review the second year of running my own mini solar power production at home.
Following are the plain unfiltered figures:
Produced : 552,53 kWh, so 121,81 kWh more than last year.
I've returned 109 kWh to the grid (for free) due to producing more than what I have used, mainly because I was on vacation away from home.
At a current price of € 0,35 / kWh it results in savings of € 193,39 for 2024, compared to € 210,62 for 2023
This is about 17 Eur less than last year where power was more expensive a year ago : € 0,49 vs. € 0,35 / kWh.
Also this is indeed a high cost per kWh compared to € 0,32 / kWh which you could get with a new contract - however, last year it was the cheapest option for us.
I am including the energy I have returned to the grid worth € 38,15 in my savings calculation because it was on me to use it.
Here is the chart showing power production over the course of the year.
In this year, the month of August seemed to be the best month, shortly followed by July - both months providing a good amount of sunlight and power output.
When putting 2023 and 2024 side by side, you can see what a difference it makes to mount panels at an angle.
I have to admit, I have certainly not mounted my panels in the most optimal position. However, it really makes a difference!
Overall a 28% more output from exactly the same modules.
Ok, great - now what's next?
UPGRADE! This year the legal situation changed in Germany. It is now allowe to run with an 800W inverter while I'm still using the basic 600W inverter.
I already bought the new inverter, but have not found time to do the upgrade. Overall I'm not expecting a huge power boost, but a small 10% to maybe 20% imporvement during peak season in summer.
TCO
Price for new solar panels has dropped to <60 Eur / piece for a 450 Wp panel, e.g. Trina Solar.
EUR 110,- for 2x Panels (€ 55,- each)
EUR 110,- for 1x Hoymiles HM-800
EUR 80,- for panel mount/equipment
EUR 50,- for some 5m solar power cables,adapters and other small parts
= EUR 350,-
Given current figures, the entire investment would have already payed off in just two years!.
Just because I bought my equipment at a slightly higher price it will take another year for me to get a return on invest.
Conclusion:
Is it (still) worth it ?
Need to repeat my previous statement from 2023 : Absolutely YES YES YES YES!
Even at current energy prices and prices of new solar panels you'll have a return of invest in under two years.
That is comparable to an interest rate of >50% - where on earth do you get that for your bank account?
My advise:
Dont wait, START NOW and install as many solar panels as you (leagally) can.
This year I helped two more friends with buiding their own "Balkonkraftwerk".
