Decrypt email passwords

Is there a possibility to decrypt email accounts password? Unfortunately, I need this to migrate from i-mscp to other control panel. Would be much easier for the users to sync content of the email accounts without intrerupting their activity.

Thanks.

I tested a lot of alternative solutions to imscp and the best I was able to find, one that does not depend on a company and that is mature enought and had a strong developers and community support was ispconfig, unfortunately it does not have a migration script from imscp so I have to do it manually.

I thought also on that.
