Ok, it seems to be a spam-issue with G-Mail - it marks the messages as spam, but not always, which is weird? (But hey, why be surprised?)
Anyway, I have taken care of it now and told the mighty AI to treat this mail nice. I hope it will all be good now.
If not, I will let you know, of course.
@matt - edit: no, still the same regarding scheduled posts:
- anonymous post, changing schedule time, moved to blog: does not appear in my inbox.
- copied the post-txt, pasted it into a new blog-post, published straight away: 15 mins later it appears in my inbox.
