I have been thinking for a while about it and also looked at other code in Exim. The point is that the pool gets released only after the message has been processed. However, as a transport mechanism dkim_exim_sign() gets called for each delivery. Normally, there are only one or a few recipients for an outgoing message. But if this were a mailing list there could be thousands of recipients, and dkim_exim_sign() would get called as many times. Memory consumption by the buffers we are talking about would therefore be considerable. Now, I don't know enough about Exim's internals to answer the question of whether there is some limit to the number of deliveries and therefore calls to dkim_exim_sign() a single Exim process can make. This would of course also limit the memory consumption. But if there is no such limit Exim would run out of memory earlier if we would scrap the buffer cleanup. At this point I must say that I simply cannot decide this. In case you can't, either, perhaps Nigel has the necessary insight.
