We are changing our domain name from email@example.com to firstname.lastname@example.org and I have a few concerns. My plans are as follows and if I missed something I'm hoping you guys/gals will chime in.
1. I was going to change the Default Policy by adding @newdomain.com to the policy and unchecking the old policy. I believe this will create email addresses for everything with the new policy, retain the email@example.com address as a secondary address and give new accounts only the firstname.lastname@example.org address.
2. Not sure about the webmail address. Currently it's webmail.olddomain.com and I want it to be webmail.newdomain.com
I've done some testing on this by creating myself an email address at @newdomain.com and I'm able to receive mail and this shows as my return address, but I want to see if I'm missing something before I "throw the switch" and do it globally.
