What sort of proportion of messages? We'd really like to get debug from the primary MX for one such, or a packet capture (though we'd want the TLS session keys for the latter, which means debug on one end). By the way - you're advertising plaintext AUTH methods on plaintext connections. I *really* hope you don't accept any plaintext-conn AUTHs from outside your organisation (and, defence-in-depth, even within is poor practice). -- Cheers, Jeremy -- ## 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/
