The mini micro classic Apple emulators related post last week became way too big, so here is the classic Apple 2/Macintosh hardware upgrade part follow-up I announced in Some notes on mini/micro Apple //e emulators.
Last week, I mentioned [Wayback/Archive] ARC Javmaster – YouTube. Let’s continue from there for an even bigger post (:
Javmaster actually has a shop at [Wayback/Archive] Welcome to the 8-bit stuff store – 8 bit stuff cool retro computer 3D gadgets and geekery with a lot of interesting (mainly Apple ][ era related) retro things like:

The plan was to run a Postfix secondary MX inside a docker container.
Below are many links that might help me to get that going.
For now, I think this is the shortlist of solutions to try:
- Docker Mailserver
- Mailcow
- Mailu

While doing some ASCII art blog-post drafts cleanup, I bumped into the (now deleted) [Wayback/Archive] Best 404 page ever? : r/ProgrammerHumor which pointed to the (also now deleted).
I got there via my (not deleted!) blog post Why I like PlantUML.
So I dug up the old archived copy of that PlantUML 404-page and made gist out of it.
I soon realised this was all encoded stuff, seemingly a mix of a ROT13 variation and some other shifting around.
Luckily the original page mentioned in the Reddit post was way easier, so I put that in a gist too.
Bot are below the blog-signature. Enjoy!
Oh, and the full text of course above the signature:

I forgot both to archive this 10+ year old G+ post and schedule a blog post about it This is nice #geekporn. ASCII Art that’s truly useful.….
ASCII to bezier drawn images in a very clever way.
Found it back when searching for prior blog posts on ASCII art, because of my yesterday’s blog-post ASCII Art Archive, so here it finally is: the links about how to go from ASCII art to bezier images. Have fun!

This finally made me perform the (long overdue) migration from Sendmail to Postfix:
The Sender Rewriting Scheme (SRS) is a technique to forward mails from domains which deploy the Sender Policy Framework (SPF) to prohibit other Mail Transfer Agents (MTAs) from sending mails on their behalf. With SRS, an MTA can circumvent SPF restrictions by replacing the envelope sender with a temporary email address from one of their own domains. This temporary address is bound to the original sender and only valid for a certain amount of time, which prevents abuse by spammers.

Via a long queste to figure out why Gmail every now and then bounces forwarded messages because of Sender Policy Framework (SPF). Below are a few of the links that brought me here in mostly reverse order, but first some links that should help me further on the topic of Postfix virtual aliases.
The sendmail setup had some features not covered below (like a catch-all forward for email to addresses virtual domains not covered by a virtual alias) which I hopefully can cover later.
One thing learned both over the past decades and related postfix material: use separate servers or containers for each of your functions. So do not mix web-hosting, outgoing mail, incoming mail, fail2ban and others on the same server.

Earlier this year I bumped into [Wayback/Archive] ASCII Art Archive
This brought back instant memories about ASCII art, so in the future expect af few unfinished blog-posts that were in my “if I ever get to it archive” about it.
Let me start with my very limited ASCII art I used in late 1980s and early 1990s newsgroup and LISTSERV mailing list signature I reconstructed from a comp.virus post¹ having some very old contact data²:
o _ _ _ _ _ voice: +31-2522-20908 (18:00-24:00 UTC)

Shortly after that, my main source of income moved from the command-line to GUI based tools, so I temporarily kind of lost interest in command-line tools and customs. In that period FIGlet (see below) got created, which I totally missed (though I vaguely remember the 1.0 version being named newban).
The link at the start of this blog post not only pointed me to FIGlet, but also has a lot of examples (like some [Wayback/Archive] ASCII Art Logos – asciiart.eu) of which many by ASCII artist Joan Stark, and also links to JavaScript based tools:

From a while ago, but this 2023 PDF magazine about building GUI applications with Python using guizero is still very fun to read:
