Has anyone had difficulty transferring from Adelphia to Comcast? I could not connect to Comcast's Server. Finally I deleted my Adelphia Accounts on Mail, and recreated them. This worked.
Did Comcast acquire Adelphia and this involves a conversion from Adelphia to Comcast?
Are you saying after deleting and recreating your Adelphia email accounts in Mail allowed you to successfully access Comcast's incoming mail server without deleting and recreating your Comcast email account?
Comcast has acquired Adelphia. After the initial switch to Comcast, I changed the email address,server to Comcast. I could not send or receive any mail in Apple's Mail Program. I had to delete these accounts and recreate them. The Adelphia.mail was forwarded to Comcast(webmail) but not to my Mail program. Comcast stated that they would continue forwarding the Adelphia.mail until December 2007.
As you discovered, it is better to create a new account in such a situation instead of changing the incoming mail server and/or user name for an existing account.
This is based on the account and associated mailbox filing structure at the Finder level.
When creating an account with Mail, an account named folder is created within the Mail folder at Home > Library > Mail which is named by the user name and incoming mail server for the account.
