Ah, but the problem being discussed here is not affecting the people doing the greylisting[*], but it is affecting other parties who are trying to send them mail. I can imagine situations where the greylisters won't listen to client postmasters asking them to stop "because my MTA can't deal sensibly with it". One obvious response is "fix your MTA". In fact, there is a general point, nothing to do with greylisting. The current rules, as I pointed out before, assume that a 4xx response to RCPT is always going to happen for that RCPT from this host, independent of the sender address. In this day and age, where more and more sophisticated checking is being done, one can argue that this is no longer necessarily the case. This implies that the sender really ought to be included in the retry key. > > If so, should it be optional? > > Definitely.

Having thought more about this, I am not so sure of that. Anybody else like to "vote" on this one? ------------ [*] Other than stopping some mail getting through to them, and how much they care about that is unknown. -- Philip Hazel University of Cambridge Computing Service Get the Exim 4 book: http://www.uit.co.uk/exim-book -- ## 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/
