Some developers incopetence can be limitless. I found e-shop which uses creative but totally silly way of integrating with e-mails. See my last rant (they send e-mail with my 'From' to themselves). As I sent them delivery report (I have SPF enabled) and wrote them what is wrong, they apologized when I came to pick up the goods and were glad that I forwarded the report (otherwise my order would be quite delayed). But hey, everything is fine, they are working on new e-shop. I said great, hopefully it wouldn't be this messed up. And I was told that yeah, the new one will block .net and .com addresses right away. WHAT THE ACTUAL FUCK? How can somebody use their incompetence as a reason to screw up even more! So next time, I'll probably use my local e-mail with SPF enabled to tech them to blick all e-mails and do stuff properly.
