It's even worse than that. Scammers are sending messages through booking.com, so you get a message from the hotel, in your booking.com inbox, with a link to a payment site that just makes a payment to the crooks. The root cause is either hotel employees installing session-stealing malware, either accidentally or by being part of the scam.
Hey, thanks for the post. I was going to migrate some of my mailboxes to Zoho (ones that mostly receive netflix receipts and junkmail), can you elaborate about lack of unicode support? I can't find anything with a cursory web search.
