When an mbox email contains a line that looks like a "Mail" header it should be quoted (per RFC 4155). Sendmail's delivery agent does this, as does Procmail delivery agent. Dovecot deliver does not do this.
Example line, with ">" quote:

When reading email (IMAP) that contains such an unquoted line, the email abruptly ends before the "Mail" line. There may (or may not) appear another email (visible to the client) that contains the rest of the email.
Dovecot is supposed to use Content-Length: header to skip over the mail body so it wouldn't require From lines to be quoted. This used to work with v0.99, but it got broken at some point.
I've also thought about quoting From line, and maybe I'll do that if I can't get Content-Length: to work properly. An annoying problem with the quoting is that it changes the mail content and breaks things like PGP signatures.
Anyway this is in my "would be a nice fix for v1.1.0, but doesn't block a release" TODO category.
Thanks for the reply!
This is a big problem when it happens; very confusing for the end user. But it seems to be a rare occurance.
