That's not quite so important. Some MUAs may lose emails when they can't deliver (especially poorly written web applications, for example). Or, they might put the mail into a local queue that doesn't get tickled for a long time - perhaps you're sending last minute instructions to your staff before you go on leave for a fortnight, for example! MTAs are vulnerable to DoS attacks, and problems with virus scanners can bring the host down. Your mailstore (if on a separate host) should be more stable because it doesn't face those threats. And, the consequence of lack of availability is less severe - the data should still be there when you next connect. -- Ian Eiloart IT Services, University of Sussex 01273-873148 x3148 For new support requests, see http://www.sussex.ac.uk/its/help/ -- ## 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/
