Run Exim daemon with "-d+auth", look for the differences bitween normal and error cases. Run some traffic sniffer like tcpdump to analyze contents of network connection. Try to reproduce problem by hands, with "exim -bh". There is nothing to discuss until you collect relevant diagnostic data. -- Eugene Berdnikov -- ## List details at https://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/
