Will changing the A record for
aaa.com cause the loss of some incoming mail?
no, if that changed ip accept delivery of that recipient domain
back to what mx does ?, it only defines a seperate hostname to deliver
mail to if mail and other servicefs on hostnamea is not same as service
on hostnameb eq if you only have single ip, do not use mx setup
people are misguided if that say mx is needed to recieve emails, i have
seen fool bounces that i need mx to recieve bounces, where the bounced
text was rejected mail from me since i did inded not have a mx, i dont
need a complex world setup for a single ip
