I did some tests.
Dragging a 7.4Mb email from cyrus-imap to Zimbra via evolution works.
Dragging 10.4Mb from cyrus to Zimbra fails with an error on the destination mailbox.
Forwarding the 10.4Mb to Zimbra works fine.
Dragging that 10.4Mb from Zimbra to cyrus via evolution works.
So, the problem is that Zimbra imap seems to have a restriction on receiving mail via imap. This also happens when running imap-sync.
