I'm going to be setting up new email addresses for a company later that has a domain setup. I understand their email settings will be different because it's going through their domain. I'll make sure to get the settings for an existing account, so I should be good to go. I just haven't seen their setup and want to be quick about it.
Would there be anything specific I should know about adding new email addresses to a domain? I may be over thinking this, but it's a new setup and want to get it right first try. I realize it's kinda open ended, but any information would be appreciated.
