I copied a few (lot) of accounts to a new server - After running into email problems I used the convert2maildir process.

Well the lingering problem is some accounts are not able to login to webmail via <domain-name>/webmail using the email full address and assigned password. This is only happening to some accounts.

I have also ran /scripts/resetimappasswds

However login is possible via the server hostname using the same login information.

Any assistance with this is appreciated.
