@wansti aha! that's good & bad news. sorry to say, but also more bad news... just like prior days, the above latest test-post has NOT reached either of my other Friendicas, which accounts i had "CC'd" above. obvs this is a bad situation. i think atm i cannot really proceed with more setting up this account, til you've had a chance to sniff about on your server in hope of finding the blockage. we do know that outbound posts are succeeding within your server (eg, you're getting mine & i'm getting yours, plus unexpectedly this morn another peep on your server, @lynfox, replied that she could see my test-post}, but mine at least have a 100% failure rate getting to the outside. good luck, & thx for your efforts!

ps: dunno if this helps with the diagnostics or not, but so far when i write posts, other than for your address, any address i begin typing is NOT recognised & auto-completed, nor pops-up a list for me to choose... instead i have to fully type in each address each time {eg, Lyn's, above}. that's not how it works on my other Friendicas, or indeed my Masto or Sharkey accounts... fwiw.
