I sometimes remember the time when I wrote a Email-inbox-exporter-PHP-script-type of application that collects all the emails from an inbox, "copied" it to a database with the attachements and stuff and moves it to a folder..

I just started at the company for like a couple of months, had no privileges to create mailboxes and such and I didn't want to interrupt our programmer to do this for me, so... I decided.. to save time and resources.. to test run it on our global, live 'support' mailbox.. :D Well.. You might guess what happened.. Apparently I mistyped the name of the move-destination folder (because imap-weird-things) that resulted in a completly empty mailbox and an empty database because the inserts failed due to bad encoding and mime-type issues..

The moment I refreshed my Outlook and noticed that all our mails where gone.. I swear, I can't describe that feeling of fear, cold sweat, intense heartbeat... I just stood up, asked if anyone wanted coffee, and just walked out of the office.. When in the hallway, I heard my collegues ask to one another "do you have any issues with outlook, all my mails are gone?". Everyone was stressing out, the chief was stressing out "what happened?!", nobody knew what happened.. :D

They could partially resolve it via one collegue who hadn't refreshed the mailbox and he could forward all the mails back to our support mailbox..

I dropped the project idea and learned to work with dev environments :D A couple of months later, I accidentially forgot a where condition in my SQL UPDATE statement, but that was the last time I seriously f*cked up.. :D Got to learn the hard way I guess.. Now everything I do runs in dev environments, I test everything before publishing,.. When I look back.. I don't even recognize the (inexperienced) guy I was back then ! :D

Ps. No one still knows what happened that day and they blamed it on server issues :D
