ok, but maybe something like exchange.visioninsurancegroup.com could
be used, too.

ah, ah, no excuses!!! :)))

use dig to look it up!!

ok, then MX records are how you're going to route the mail there.
# dig visioninsurancegroup.com mx

btw, MX 0 is an open relay. and why have identical MX hostnames??

nope:

You need MX for mail.visioninsurancegroup.com and visioninsurancegroup.com
plus an A record for each, GAMEOVER.

evidence??
the DNS setting I are correct, for mail to go "MX 0
mail.visioninsurancegroup.com"
>In viewing the dns records with online tools, everything looks ok.
yep

maybe you DNS caching of MX records screwing you up. It doesn't help
at all that ns1 and ns2 aren't responding (08:30 Paris time, Tue),
but here's what I see and it looks cool:

that should work, with mail going to mail.visioninsurancegroup.com

see above, there is definitely a A record for mail.visioninsurance.com

no, there's nothing wrong with your idea. all you're doing is
setting up mail routing in DNS so visioninsurance.com's mail goes to
mail.visioninsurance.com, absolutely vanilla setup.

you can do it now, you can do it later. Figure out why ns1 and ns2
aren't responding for me.
