OK, Rich provided the clue. It turns out that, randomly, a few weeks ago, some posts from utah-astronomy started going into my bulk folder (spam), where I have directed that they be deleted on receipt. I have no idea why some (including my own) go to "bulk", while others get through to the "In" folder. The same sender will get randomly sorted first to one folder, then the other. It appears that the problem is with Yahoo, in my case at least, and the criteria they use to distinguish spam. I have now changed the "kill on receipt" setting and will have to weed through the spam to get the astro-list postings, but it appears that I at least will get them. Others with a similar problem may want to investigate the same possibility. ____________________________________________________________________________________ Finding fabulous fares is fun.
