Treatment of a dot/period/full stop and a plus symbol + in paid accounts
I am planning to use the paid mailbox service, primarily for email for approx 10 users on a custom domain. I have two questions:
Second, can anyone explain how the mail server treat a period/dot/full stop? For instance, is there a difference between email@example.com and firstname.lastname@example.org? Can they be used interchangeably by the same user?
Thank you for your help.
