Hi Don, The email address you have mentioned are treated differently on email server. don.hollander@gmail.com,don_hollander@gmail.com and donhollander@gmail.com are different mail box. RegardsDeepak Singhal. From: Don Hollander MailId : [68280110]To: "ua-eai@icann.org" Subject: [UA-EAI] Normalisation normsDate: 19 Apr 2017 12:55:19 PM During last week&rsquos discussion we talked about normalisation of case (upper case/lower case) and we affirmed our suggestions outlined in the Quick Guide to EAI. What are people doing about punctuation within a mailbox name? I THINK that Google strips all punctuation marks when finding the mailbox to deliver to. Thus, don.hollander@gmail.com = don_hollander@gmail.com = donhollander@gmail.com Is this another Good Practice to include in our EAI guides?
