This was before I was made redundant ,which happened for unrelated reasons and was ok.

I worked at a startup. Before I started, the company had an NT server running Exchange, which contained all customer relationship data, emails etc. The box was also a fileserver. One day, space was running out. The "admins" (== developers who only knew Linux) solved the problem by deleting all the "*.log" files cluttering up the filesystem, thereby effectively lobotomizing Exchange.

After some weeks a highly-paid consultant gave up. The company needed a new email server.

The devs decided to use qmail, because "secure". To translate between the firstname.lastname@company.com address to the firstname_lastname directory, a Perl script was inserted between qmail and the mailboxes. As time went by, this Perl script metastized to include email renames and even out of office replies. It grew to ~300 lines and was run on every single email that arrived.

After a while we got acquired by grownups who knew how to manage Exchange. I discovered that if an email was misplet, it wasn't bounced, instead it was forwarded to root's email account, which was a couple of gigs in size.

I swore to never touch email administration again.
