Did you in-fact check the headers of the emails that were delayed as I 
Steve's last email suggests you're far from moderated. Again, look for a 
technical issue - not a malicious one.

Your email of 16.12 displays header Date: line as follows:
Date: Fri, 15 Jan 2016 07:12:21 +0200 (Why are you set to UTC +2 ?)

It was received by my MTA, through my anti-spam service provider, at  15 
Jan 2016 18:12:45 +1300 (NZDT) - So it took 24 seconds +/- clock 
variance between your machine and my MTA.
Your follow-up email of 16.22 shows Date: line of Date: Fri, 15 Jan 2016 
07:22:36 +0200 and was received by my MTA at Fri, 15 Jan 2016 18:22:58 
+1300 (NZDT) - 22 seconds throughput time.
The only copy I got, was through the listserv.

Again, don't make assumptions. You could (for example) review the web 
archive to see if your message has hit the list proper or not, if you 
want to see what others might see in terms of subscription-vs-delivery. 
Or you could subscribe an additional third-party email address as a 
sanity check.


PS: Following the threads here the spawned from my initial PSA has been 
enlightening, both in terms of the cloo level's demonstrated by many in 
the community - and also in some of the misunderstandings about some of 
this stuff. LCA talk material, maybe? :) It sounds like the LA 
backend-horsepower are working pretty hard to find new hosting for 
services pretty quickly, maybe in the aftermath a report to LCA would 
help some participants understand exactly how much volunteer effort goes 
in to keeping LA ticking...
