there are few serwers using rather stupid anti-spams. and they treat it as 
spam. then user complain that mail doesn't get to the receiver.

then i look at logs and paste a fragment about when and why mail wasn't 
received, or (more often) was received by target server.

the next question is for target server's administrator. that are normal 

not that someone use crap as anti-spam, and i (or you or else) then needs 
to avoid being treated as spam.

this is normal procedure and normal rules, and not reverse.

what mail server admin should do is to receive incoming mail and make sure 
it will go where is should. not install some stupid program and be happy.

even more - quite often mail from my servers, these having reverse DNS 
mappings etc.. are treated as spams. most often by large sh..s like 
gmail, hotmail, <lit of polish similar things>, etc... which has spam 
policy as below:

- everything that comes from us or our friends are mail
- everything else is probably spam, if it not, don't care.
