That's fine, everyone has different opinions of best practices. Use whatever works best for you. Every user environment is different. > 1.

I think the majority of our users would be very annoyed at having their entire message rejected because a single recipient was mistyped. Explaining to a user that they need to go to their Outbox and either delete or edit the message that is trying to resend is much more difficult than telling a user to simply resend to the persons in the bounce message. Our users much prefer getting 199 out of 200 recipients delivered when only a single email address is mistyped instead of rejecting the whole thing outright. As far as your original question, about how to override the "host lookup did not complete" message, I have no idea. The context is obvious to the MUA (it knows which recipient was just sent and returned a temporary error). I don't know if there is a way to override that error message. I doubt there currently is, given that its not a verification failure, its a deferral. I would venture most larger Exim installations have local MUA recipient verification failures generate bounces, so not sure many people would have run into this before. -- Dean Brooks [EMAIL PROTECTED] -- ## List details at http://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/
