I have just started to use virtualmin and i come from whm/cpanel. I have setup everything, migrated all virtualhosts from cpanel to virtualmin using the migrate server option. Everything seems to be running smoothly but the problem is with emails. The transferred email accounts exists and users can login with their old credentials but most of the old emails appear blank and from unknown sender.
Here is a screenshot: https://i.imgur.com/Inis6Y6.png
While the content is random dump data, which seems like content is in an unreadable format.
Any help would be greatly appreciated.
