Please post again those messages and check if they get through (you may post just one of them again and wait to confirm the success before posting all others). Note that Nabble doesn't re-send pending messages. Users must post them again (after realizing that something went wrong). If your next attempt still creates a pending post (i.e., still pending after a few hours), you should try sending the post as a normal email to the mailing list (remove Nabble as a variable).

Hi Graham, please try to post your message again.
Eighteen messages recreated and re-posted, hopefully in an order that will make sense when readers receive them en masse. At least one of the recreations included a cross-reference to a post that was to be deleted, this was all a bit mind-bending.
