Duplicate emails received
We are new to DigitalOcean and this may have been asked and answered in the past. My search back through previous questions so far doesn’t show that though.
Some emails for one of our domains have been lost on a number of occasions in the past 12 months or so due to the intermittent poor reputation of the email server of our hosting provider. Therefore we have setup a droplet here on DO to use as our mail server to avoid this problem occurring again.
However, we are receiving two copies of all our emails for all email addresses on that domain. I have just had a look at the DNS entries for the domain in question and there are two A Records. One points to the new DO droplet and one is to our local ISP.
Will the existence of the two A Records likely to be causing the duplicated emails? Does this mean that our emails are being routed through both email servers? Can I simply delete the non-DigitalOcean one without causing any other email issues?
I am very new to all this, and was not involved in setting up our DO droplet so am wary of doing anything that could further disrupt our emails.
Thanks in advance for any enlightenment on this.
