Add other mailboxes to Alibaba Mail to fetch and back up emails from external accounts.
Procedure
1. Back up emails by fetching. Log on to the Alibaba Mail web client. Go to Settings > Mailbox Settings > Other Mailboxes and click Add Other Mailbox.
Receiving emails:
Ensure that the POP protocol is enabled on the target mailbox, and then use the auto-detect POP server feature.

You can also enter the POP server information for the target mailbox manually.
