Checking email
I used to set MailWasher (my email frontend – it displays the mail on the server, so NOTHING that’s a problem hits my machine….) to check mail every three minutes. Lately, I’ve changed that to an hour. I’m pretty sure nothing is that important any more….
Though if I KNOW a client is having problems, I do check more often, but normally? Nope, once an hour is often enough.
