No idea, it seems that your 1st mail triggers some kind of "already seen 
then allowed" scenario for subsequent emails (such as some firewall 
rules that allow traffic from both side after it was initiated by one 
side ?)

But to debug this we would need access to tuxfamily's mail servers logs 
(which we don't) or to you ISP logs. Maybe you can try to ask them, it's 
often complicated to find someone on the ISP side who accepts to look at 
such specific issue, but who knows ? And maybe your ISP made some 
changes on its side that could explain this.

Maybe if you have another email @seimet.de then you can try to subscribe 
to hatari ML with this one too and test if they both have the same issue 
or not ? which could give a hint on which side the problem might be.
