I'm not sure if it's the same bug, and I wouldn't be surprised if the behavior was deliberate in that case (after all, the whole "long failure period" business is there to generate immediate bounces, so that users won't have to wait for five days until they are told about their mistake). In the example in the bug report, we there are two A RRs: mailrelay.direct-adsl.nl. 86400 IN A 195.121.6.12 mailrelay.direct-adsl.nl. 86400 IN A 195.121.6.56 But resolvers MUST cache the whole set of records and expire them at the same time. If the resolver fails to do this properly and provides a wrong view on DNS, there is no workaround on Exim's side. -- ## 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/
