Nowadays such behaviour may be considered as a bad practice, and users could protest against this idea. I suggest you to look through RFC 3438, "Recommendations for Automatic Responses to Electronic Mail". > Can it be done, presently, without simply routing such mail through a proxy > that re-injects it?

Read https://www.exim.org/exim-html-current/doc/html/spec_html/ch-the_autoreply_transport.html and around. Fuctionality of "autoreply" tranport may be implemented and/or extended with external script, which gets mail via redirect router with "unseen" option. -- 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/
