understood - i’m not running a critical site so i’m not so worried about something exploding along the network, plus a i already have a tamp backup landing page
on to mail… another nightmare that haunts me 
-
given i’ll be using a 3rd party mail provider, can i dump dovecot, postifx and bind?
-
how do i configure the server so that it sends mail to my provider (i didn’t find anything in the docs)? i assume an MX record is involved, but i know little about this
-
on my old server i had DKIM, DMARC and SPF implemented in an effort to keep a the IP clean and add some security/trust - all this is moot when using an external mail server, correct?
