I haven’t even cracked it in years… I’m still using sendmail, but my distro has gotten a lot better about having config files for the config files so that I don’t have to dig around in the guts of sendmail.cf myself.

I once wrote my own database-backed personal finance software because I figured it would be easier than getting gnucash to compile.
