It should say the OHN of the IP-ful virtual host, yes, mail.tio.nl.

That's  absolutely  right. You'll likely have to make Registry changes
if  what  you see in the GUI suggests that mail.tio.nl should be used,
but it isn't.

When  you  are  using  *only* IP-ful virtuals, you should be fine with
multiple  HELOs,  as  long  as  each possible outbound path matches up
HELO-PTR-A-IP.

The  problem  is  that  when you are using IP-less virtuals, mail from
those  virtuals  will  fail  a  HELO-PTR-A-IP  roundtrip  set of tests
_unless_  you turn on the new (in 2006.1) use-single-HELO setting. But
turning on that setting can break IP-ful virtuals on the same server.

So  the  general rules of thumb are (a) if you are using only IP-fuls,
don't  turn  on use-single-HELO, but of course make sure HELO-PTR-A-IP
match;  (b)  if  you  are  using  only one primary IP-ful and the rest
IP-less,  turn on use-single-HELO and make HELO-PTR-A-IP match; (c) if
you  are using at least one IP-less and more than one IP-ful, you will
do  best to convert all the non-primary IP-fuls to IP-less and turn on
use-single-HELO as in (b). Alternately, using an outbound gateway lets
you  not worry about IMail's options, since you can easily "multiplex"
it through the other daemon.
