@cosmin Glad it finally worked! And yes, that is a legitimate concern about your main email address.
I've just sent you a new email. This one has no links on it, and it is from another account of the same domain, with the subject "Does this mail arrive?"
If it does arrive, some (too strict) anti-spam measures of your provider are in place. If it doesn't, well... you should talk to them, because that's what gmail also does, deciding which mail arrives to inboxes, and that is not acceptable. At least, you should have a "spam" folder routed, so you can decide what is what.
