Inside organization settings, we can set "Main Domain" to "Auto Add Members From".What if organization have multiple domains such as shop1domain.com, shop2domain.com, companydomain.com - can we add them all into this field separated by comma, semicolon or space?
Yes you can and we have ours separated by comma.
Does the domain field have a limit on the number that can be in there. I have a client that has 10 to 12 domains that would fall under the same org.
It looks like the field is VARCHAR(256) in the DB. So you could update the field to be able to fit a lot more in there. I have no idea if there is another limit other than that.
