we have some servers working (high volume) and some servers not working (rather low volume), all with matching ptr and A records, not known to be blacklisted and so on. personally i think they did some changes to this end of last week - we have been watching some @hispeed.ch or @swissonline.ch queues start growing on friday last weeek. > > Of course they don't remove it automatically, you have to reach their > mailadmin to do so, which isn't quite easy.
