The machine will run fine. The question is do you need it to send you email for alerting reasons?

Mail delivery can still work with sendmail turned off. The daemon is just there to receive mail.

This guy explains it better than I can:

There's no reason to turn the MTA on unless you're running a mail server. Non-mail servers should just have a cron job flushing the submission queue just in case, but the MTA itself doesn't need to run.
