> However, for SBI, I saw recently that they have become pretty Internet savvy -- they own the `.sbi` TLD.

Non-classic TLDs get the worst search and email filter ratings, don't they?

That gets repeated a lot, but I've never seen a confirmation. There may be a perception like that because non-classic TLD are usually cheaper, which leads to easier spam. But that's still a problem with the specific domain, not the TLD.

The only confirmed thing I heard is manual email filtering where some people don't understand the bias above and ban all non-com/net/gov emails and think they're clever.

There is some basis of the fear of new gTLDs being unfavorable. Remeber free-as-in-beer ccTLDs like .tk? They were (are?) indeed ranked lowered than .com et al due to their nature as being too easy for a spammer to have a new domain. Nowadays though most search engines now include age of domain in their ranking algorithms so this is no longer a real issue.

Not just manual filtering, there are many automatic/default filters like "KAM_INFOUSMEBIZ = Prevalent use of .info|.us|.me|.me.uk|.biz domains in spam/malware"

It's not a guaranteed strike but I just had a look at the last email I had from a .biz and it got 0.8 added to it's spam score because it had a biz domain. Still got through as it was otherwise legit though.
