The easiest route would probably mean to install a minimal MTA providing /usr/bin/sendmail, like 'msmtp-mta' or 'nullmailer'
msmtp-mta simply provides a symlink from sendmail to msmtp. I believe msmtp doesn't do queueing on it's own (there's msmtpq, but that's not what the symlink points to) so unless you want to loose mail if your mailserver is temporarily overloaded, the network is down or something else is broken you shouldn't use it. That said msmtp is fine for "interactive" use. nullmailer seems to do queuing, but it doesn't seem to support bouncing when errors occur (TODO says "Generate bounces for permanently failed messages" for years now) so might not be that good a choice. Just learn and use postfix. Might take a while at first, but it supports all use cases and is well maintained.
