using sendmail command

[Clark Nova]

If I want to send the last 30 lines of a file to an email address, I need to use sendmail, am I right?

I have tried this command but no email ever came through:

tail -30 /var/log/dist-upgrade/apt.log | sendmail [email protected]

Obviously substituting my actual email for the fictional OcUK one. Am I doing this wrong? I'm just guessing this is correct but perhaps one of the more enlightened members can tell me where I'm going wrong.

Not to worry, my email account was filtering it as spam because the email didn't come from a recognised ISP. All solved, move along!
