Thanks, It's curious that there had been so many from .br domains that I had supposed it to be some kind of local custom - analogous to the way that many Chinese MTAs seem to reject "mail from:<>" out of hand. But I hadn't done any kind of statistics - this was just based on seeing what was flying past our mailer. The most recent example seen here was planetaeducacao.com.br, here's a test to confirm it: RCPT to spoofuser was refused: 450 <[EMAIL PROTECTED]>: User unknown in local recipient table And here's their SMTP banner: 220 plmail.planetaeducacao.com.br ESMTP Planeta Educação Not sure how much that tells us, though. Similar response from brasilux.com.br: 450 <[EMAIL PROTECTED]>: Recipient address rejected: User unknown in local recipient table where the banner is: 220 serverlinux.brasilux.com.br ESMTP "Version not Available" The sender addresses in question may very well be faked, of course: I'm not accusing these particular domains of being spam sources as such - merely of responding in an unhelpful way. And these are only two examples from quite a list that I collected over time. -- ## List details at http://www.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://www.exim.org/eximwiki/
