Thanks very much You should seriously consider setting up a router that allows you to use auth user names as local parts (or, alternatively, changing the auth user names to match the existing local parts), though. With sender_retain, you're trusting your users to set the correct From address, which is trivially spoofable. Tony's verify=sender suggestion will ensure that the bounces are deliverable, but it can't ensure that they're deliverable to the user who actually deserves them. This is particularly important if you allow users to send mail From shared role accounts. - Marc -- ## 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/
