Using journalctl

[Alex]

Hi all,

I've used journalctl to do some really basic things, but I'm trying to
use it to view the former /var/log/maillog, and haven't been able to
figure out how.

I understand I can use it to search for a specific priority, but
haven't figure out how to show only today's mail.* facility logs,
using the short form hostname. I also understand you can view logs for
a specific process or pid, but that's also not what I want.

Ideas greatly appreciated. A FAQ or general usage doc would really be
appreciated (beyond just the man page). It just seems like a lot more
typing than just "tail -f /var/log/maillog" when that's all I need.

Thanks,
Alex
