Reason: Cannot conect to mail server localhost:143. Authentication for mailbox mail@example.com failed. Reason: Login failed. Server answer ABCD_2 NO LOGIN Failed - The mailbox you specified does not have access to this service.

Cause

The domain is suspended/disabled or mail service is deactivated for this domain on the source server so mail service is not available.

   In case domain is suspended

   • Go under Plesk > Domains > example.com.
   • Activate /enable the domain.

   In case the mail service is disabled for this domain

   • Go under Plesk > Domains > example.com > Mail Settings.
   • Activate Mail service.
2. Log into Plesk on the target server.
3. Restart migration for the affected domain.
