Message body is missing

[yet]

Hello,

Could you take a look at the following issue:

I use movemail (GNU Mailutils) 3.12, installed from Homebrew:
https://github.com/Homebrew/homebrew-core/blob/HEAD/Formula/mailutils.rb

I cannot fetch an email message body.
It does available on the server and is loaded without issues by iPhone client. 

I encountered the issue with Emacs Rmail and reproduced with this CLI command:

movemail -pv imaps://yet%40ego.team:pwd@imap.migadu.com:993 
~/Downloads/movemail-test1
movemail: number of messages in source mailbox: 8
movemail: number of processed messages: 8
movemail: number of errors: 0 / 0

I'm not sure how safe would it be to share the mail source, so temporarily 
uploading it to:
http://phpstack-212214-770765.cloudwaysapps.com/support/movemail-test1
http://phpstack-212214-770765.cloudwaysapps.com/support/1-wembail-message-shown.png

The email with missing body is the first one in the provided file.

So far - I'm new to both mailutils and used IMAP server - this was the only 
such problematic email.

Any ideas what could go wrong here?

Thank you,
YE
