When I update to Apsose.Email 19.11 (.NET) from 19.10 the MailMessage object (received by ImapClient.FetchMessage) contains no informations. The object is not null but all relevant fields like Body or Attachments are empty. Also when I choose saveMessage I get a 0 bytes file.
For testing I used the same emails from Gmail and Strato by IMAP.
When I receive the same emails with version 19.10. everything is working. Also when I receive mails with POP3 and version 19.11. everything is working.
