Of course not. but people need to be aware that most programs will use /usr/bin/sendmail to inject mail into the local MTA's queue, and if they do so, they do not require the MTA to be listening on port 25.

No. It _can_ be performed with sendmail (or exim - in the current discussion we've been discussing exim but no mention has been made of the fact that exim installs itself with the synonym 'sendmail'). But there's absolutely no reason not to use SMTP for queuing local mail if your preferred MUA can't pipe to a native program (fairly common). If exim is configured not to accept SMTP connections except from the local subnet (common for this kind of laptop setup) and you have appropriate firewall rules, there's nothing to fear from letting exim use SMTP to queue local mail.

That sounds like it must be the time required to start from inetd. If you run exim as a daemon, it can do exactly the same things without the startup overhead.

If exim is > not running, will it not fail?!? I use much the same config. Exim can be running but not necessarily ready to run the queues at the same time as you connect, so you have ifplugd, or whereami, or some other network-aware program, do an explicit queue run at connection. Meanwhile, exim doesn't need to know if it's offline - you send it mail, it tries to forward it, and if it can't it puts it in the queue for retry.
