Mail Migration from Confixx

The model of mail objects is different for Confixx and for Plesk.

In Confixx, each e-mail address can be associated with one or more
mailboxes, and each mailbox has an automatically generated name. For
example, the third mailbox of the customer web4 will be named
web4p3. A user can login to a mailbox by POP3/IMAP/SMTP using the
mailbox name as a login name.

In Plesk, an e-mail address can be associated with only one mailbox. A
mailbox has no separate name but is just related to an e-mail address. A
user can login to a mailbox using the e-mail address as a login name.

When migrating from Confixx, there are two possible modes of mail
mapping between mail objects: Default and Short names. In the
Default mode, the user will have to use an e-mail address to log in to
a mailbox after migration. In the Short names mode, the user will be
able to log in to a mailbox using the mailbox name as they used to in
Confixx.

For example, if a Confixx user has the e-mail address [email protected]
associated with the mailbox web4p3, the behavior of the Plesk Migrator
will be the following:

• In the Default mode: After migration, the user in Plesk will have
  one e-mail address [email protected] associated with a mailbox that
  will contain messages from web4p3. The advantage of this method is
  that the structure of mail objects in Plesk after migration is simple
  and can be easily managed. The disadvantage is that the user will
  have to reconfigure the mail client to use [email protected] to log
  in to the mailbox instead of web4p3 that they previously used in
  Confixx.
• In the Short names mode: After migration, the user in Plesk will
  have the fake e-mail address [email protected] and the mail alias
  [email protected]. The address [email protected] will be
  associated with a mailbox that will contain messages from web4p3,
  and the user will be able to log in to the mailbox using the short
  name, i.e. web4p3, as they used to in Confixx. The advantage of
  this method is that the previous login name can be used and there is
  no need to reconfigure the mail client. However, the disadvantage is
  a more complex structure of mail objects in Plesk.
