Ohhhh... nice to know.  Last time I'd checked -- when IPv6 suddenly was 
blocking my outbound -- it was an intentional block, with no intention 
to remove it.  I guess times have changed.  (The rationale was that, 
apparently, RBLs were blocking entire v6 subnets, so rather than maybe 
not be able to send email, they'd save everyone the unpleasantness of 
uncertainty, and simply block it entirely.)

Good deal.

Huh.  I did have to bounce the first IP I got some six(?) years ago, but 
been smooth sailing since.  However, it's good to know it's not a DO 
priority.  I'll keep my eyes open for bounced/bitbucketed e-mails.  
Indeed, right now, I'm waiting on a reply to an e-mail I sent to a guy 
who's usually really quick with replies.  But it's also a holiday, 
basically, so I'm not getting exercise jumping to conclusions.

Boo!  Hiss!
