Here’s to the simple solutions

For the past couple of days, Mail had stopped working. It couldn’t connect to the email servers for some reasons and kept taking my accounts offline. I knew I hadn’t changed any of its settings. In all my years of using a Mac (since 1994), I’d never run into a situation where Mail settings had gotten corrupted, but I was now willing to look into it. I kept looking at all sorts of scenarios and guides online — things such as these (1, 2, 3, 4) — but nothing helped.

Then it occurred to me that three days ago, as I worked late, past midnight, I got the bright idea to switch the firewall level to High from Medium. “Oh, let’s get some extra protection, shall we?” My router is one of these gizmos handed to me by my ISP, it’s a ZTE that came with no printed documentation and barely any online documentation beyond “this is ON button, this is internet port”. So how was I to know that switching it to High would mean all traffic other than port 25 and 80 would be closed off? But that’s what happened. I did it, forgot about it, and when my email stopped working, it took me a couple of days to connect the dots.

I’m writing this down for you because it’s a great reminder that sometimes the simple solutions are the best (and possibly the only) ones. That, plus writing down changes to the internet configs, especially when I’m working late… Sure, I could have taken a dive into deep-level Mail documentation and email servers and the intricacies of setting up IMAP and opened up ports on my firewall and deleted my Mail settings and set up everything again, but all it took was me logging onto the ISP router and switching the firewall back down to Medium. Less than a minute vs. hours and hours of needless work.

Good to know, right?
