Be careful with assumptions and abstractions. :) We're talking about _defaults_ though, so it's not entirely unreasonable to make such generalisations. According to your Received: headers, Fedora's defaults have already failed you -- you've already installed Exim from Extras, and presumably removed sendmail. Would it really matter to you if it were been some simple outgoing-only relay tool that you'd had to remove, instead of sendmail? My point is that if we're going to pretend to be rational and consistent, there should be _one_ package providing /usr/lib/sendmail in Core, and those other than the default should be in Extras. Currently the default is sendmail, which means postfix should be moved to Extras. Whether the default _should_ be sendmail is a separate question. There are arguments for it being sendmail purely because that's 'expected', which sound to me much like the arguments that computers should come with Windows because that's 'expected'. There are arguments for it being a simple relay which can only handle outgoing mail and no local delivery -- even mail to root@ can be set up to forward to a real email address elsewhere. You're right that that wouldn't serve everyone -- but the GNOME folks have made far _worse_ generalisations on Fedora's behalf, and at least this is one decision that we can override for ourselves just installing a proper MTA. There are arguments for it being Exim, which is capable of acting as simple outgoing relay and is _also_ capable of much more; spam checking, antivirus, greylisting, etc. -- all without third-party software (other than SA and ClamAV themselves). I think that's probably the best choice -- it's easy to configure, well documented, more functional than any of the alternatives, and has a good security record. It also has complete and _mature_ support for IPv6, unlike postfix which was recently observed to be bouncing mail for domains with IPv6-only primary MX. I'm sure someone can contrive some kind of spurious argument for it being postfix, too -- despite that fact that postfix doesn't match Exim in functionality and doesn't match either Sendmail or Exim in ubiquity¹. -- dwmw2 ¹ http://www.securityspace.com/s_survey/data/man.200605/mxsurvey.html
