Question Plesk Migration with SmarterMail

[mohemmadAli]

While migrating all accounts from SolidCP to Plesk, I need to add an existing SmarterMail (with active accounts) to Plesk Panel and import all the inboxes to the respective subscriptions in Plesk. I appreciate any suggestions on it.

My problem is slightly different (but, possible the same). I have a domain that I'm trying to add to Plesk that currently has several email accounts hosted in my SmarterMail server. When I try to add the domain to Plesk, I recive an email creation error and the domain fails to be created in Plesk. My question is; is there a work-a-round for this issue? I need to be able to keep those accounts active and cannot just delete the domains from the SmarterMail server. Doing so would lose GB's of emails.
