For instance the pope could get pope@va - if he wanted...
- xyzzy123 14y agoTry connecting to those on port 25, see if any accept mail... they don't tend to.
- macspoofing 14y agoBut they can. In this case, you probably won't alienate any of your potential users but as you add more and more arbitrary rules, you will.
- xyzzy123 14y agoFair call, I'm all for fewer arbitrary rules. Especially if it's less code. I still consider the "oh, but it's valid to have dotless on RHS!" to be one of those facts which is true, but irrelevant. Those three hypothetical users can't receive email sent from most major web providers (e.g. gmail, who don't allow dotless To:), can't sign up to most web sites (who get their validation wrong), and are at the mercy of pitiless local dns resolver rules (pope@va will go to pope@va.com for US users, a lot of the time).
- VMG 14y agoTry connecting to those on port 25, see if any accept mail... they don't tend to. That's not a test for validating an email host either - looking up MX records would be more appropriate here.
- xyzzy123 14y agoI actually meant the MXs, sort of thought that went without saying.
