I'm just trying to confirm my understanding of how mapped domains and e-mail work together.
For years, I've had mydomain.com registered and hosted at Dreamhost.
For a new subunit, I set up subgroup.mydomain.com and configured it to use Gmail for mail service. [That's a feature in the Dreamhost admin panel.]
Then I decided to host the website at WordPress.com, so the WordPress site is set up as
mydomainsubgroup.wordpress.com
and at Dreamhost I've reconfigured the domain so that
subgroup.mydomain.com forwards to mydomainsubgroup.wordpress.com.
E-mail is working find to addresses like info@subgroup.mydomain.com.
From what I can find, though, if I now decide I'd like to pay the extra to WordPress to have subgroup.mydomain.com be the address for the site, that's going to break the mail service. I'd need to reconfigure things to put all the mail addresses on something like mail.subgroup.mydomain.com.
In other words, there's no way to have subgroup.mydomain.com bring up a WordPress.com site AND have info@subgroup.mydomain.com actually work (with Gmail or whatever).
Is that all correct?
TIA
