Zombies do both, but my comment wasn't about zombies, it was about  
users.  If you are a user with a vanity domain trying to send e-mail  
"From: user at vanity.domain", you cannot through VZ's system.  Despite  
the fact we have spent years telling people they have to use their  
local ISP's mail server to send mail out.

Does VZ support SMTP AUTH these days?  (My info is over a year old.)
