My problem with SPF (& co) is redirections.

I have email redirected from other domains into my (Gmail) inbox. For it to arrive, I use SRS, so the email is properly aligned and always makes it into my inbox. The problem is that some of that email is malicious. I have a choice of dropping those mails, and I never see a trace of it in my inbox, or forwarding them with SRS, and they look to Gmail like 100% perfectly good mails sent from my own domain (but still potentially malicious). It's annoying.

> It's annoying.

This seems very much like a problem you have created for yourself.

I know, how dare I use other domains than gmail...?

Why post a comment at all, if you have no insight. It's useless and insulting.

Why post on a public forum if you dont want, or even get insulted by, other peoples opinions?

Its nothing to do with using domains other than gmail, its that you said you are actively relaying all mail into your gmail account and rewriting the sender as yourself, but then its annoying that spam gets marked as valid mail from your domain. Thats nobodies problem other than your own setup, and there are loads of other ways you could do it. But the way you chose to set it up is 'annoying'.

Sorry to insult you, but I feel that warrants letting you know you caused your own problem!

If your opinion is "you suck" it's called an insult.

You could have ignored my question, you could have explained why I'm doing it wrong, hell you could have posted a random setup guide from Google and downvoted me. Instead you post this attack with no content, justification, or insight. You are being an ass. You are allowed to be, but I'm allowed to call it out.

And if you think I set my email up in a sub-optimal way, just so that I could ask for advice on HN, with the goal of pissing you off... you are delusional.

Since you seem so well versed on how the best way to not be insulting, maybe you should follow your own advice and stop insulting other people. Just a thought, but maybe if you tone down your responses and be a bit less insulting yourself then maybe karma might do you a favour.

Take a look back at the thread. This is what I posted:

> This seems very much like a problem you have created for yourself.

Thats it. Nobody said you suck, nobody insulted anything. Just pointed out that a problem you said was annoying was caused by your own doing. If you think that is an attack, and warrants calling me delusional and an ass, then you need to look very hard at your own reactions to things. You resorted to namecalling and mudslinging just a bit too quickly.
