You haven't truly lived the life of a #sysadmin until you're googling around to figure out some issue and find a post about it where someone's asking the exact same question and... it's you. You, asking the exact same question ten years ago. And nobody answers.
Today while training some sysadmins I shared this real photo of ancient Greek engineers configuring a mailserver.
On the left the brave engineer is trying to stop unauthorised pipelining through the MTA as their knee is viciously attacked by a subtly broken DKIM key. Meanwhile, their co-sysadmin is hammering away at a perfectly good Postfix sender restrictions policy, screaming "It's not DNS!", while bitten by a PTR record quietly hissing "It'ssss DNSssss".
