This is yet another bug in hotmail (maybe in other MS products too, but I haven't verified yet). If you reject a mail after the data phase with a multiple line answer, the server just don't issue QUIT and thinks it has failed the delivery. My configuration helped legitimate people to understand why their mail has failed with: control = fakereject/Message rejected due to spam score: $spam_score\n$spam_report When I changed it to: control = fakereject/Message rejected due to spam score: $spam_score hotmail servers issued the QUIT and didn't retry. So I guess this is due to the multiline reply. -- ## List details at http://lists.exim.org/mailman/listinfo/exim-users ## Exim details at http://www.exim.org/ ## Please use the Wiki with this list - http://wiki.exim.org/
