I think I know how this plays out, but there are so many handy exceptions for real use cases in exim that I thought I'd ask. :-)
Once message reception has moved on from routers to transport, are all rejections done in the form of generating a bounce message (as opposed to an SMTP response code)? I think so, but I've been pondering both the book and the spec for a few days and haven't found an explicit statement to that effect. Is there any transport that can fail a message and have it result in an appropriate SMTP response code? The use case I am looking at is approximately as follows, so I'd also be interested in approaches others have taken in addressing it. For (uninteresting in this context) functional reason, I want to use a 3rd party LDA. The LDA will enforce quotas. I want to avoid backscatter spam when someone's mailbox gets full and additional spam keeps pouring in. Right now, I don't have a centralized source of information about the quota status of a user outside of that LDA. (My local policy is to never have the system discard what it thinks is spam, but my users are empowered to do so various ways. However, some of them are unsophisticated enough to let their mailboxes fill up with it.) -- [EMAIL PROTECTED] (WJCarpenter) PGP 0x91865119 38 95 1B 69 C9 C6 3D 25 73 46 32 04 69 D6 ED F3 -- ## 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/
