If you take out sendmail first, it removes other dependent stuff, but if you install postfix and the switch-mail util, when you remove sendmail it goes away without complaint.
'Stuff that needs sendmail' normally executes a command named sendmail,
usually as /usr/sbin/sendmail. Installing postfix will supply one, and
system-switch-mail manipulates which one is active if you have both
through a symlink scheme. If you try to run something that needs
sendmail without a working /usr/bin/sendmail program, it will fail to
deliver anything but your system won't crash and burn.
