I haven't noticed any recent change, but in general it seemed that Gmail was very strict on email delivered via IPv6 for the past couple of years, whereas the same sender domains saw no problems when mails were sent over IPv4. Don't have any hard data on this, just casual observation. Though at some point I made sure that my systems don't use IPv6 for outgoing mail.
