Now I reject by 554 code... should I change to 4xx?if it suits your needs. i wouldn't.
I have to agree with that statement. For us it suits our needs very well. I don't mind handling the extra retry traffic if it means legitimate mail on a 'grey/pink' host is just temporarily rejected or delayed while they clean up, in fact this is far more desireable for us. Complaints of 'lost' mail went up when we were using permanent fatal codes as an experiment. Yes legitimate hosts get blacklisted, but legitimate hosts will retry, and if they don't well, it's their problem, not ours. We're telling them 454 listed on spamciop see URL of whatever (I'm obviously paraphrasing)
