Thanks Alan,

Yes i'm aware that many people don't know how smtp works, and that ISPs 
break it badly while trying to fight spam (btw this is why i run my smtp 
servers, some of the things isps do are totally unacceptable and 
uncontrollable by the end user).

This is why i asked for info from people that are getting bounces, and 
that didn't have problems previously but now have them (maybe i didn't 
write this clearly enough). The list has been quieter lately. I know of a 
user that started to have problems recently, and bounces related to tls 
problems (probably related to people being more keen on upgrading openssl 
recently).
