But you didn't say what this possible 5XX might be a response to. I assume you've read http://exim.org/exim-html-current/doc/html/spec_html/ch-retry_configuration.html You might also look at http://exim.org/exim-html-current/doc/html/spec_html/ch-exim_utilities.html#SECTfinindret -- 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/
