OK, I've applied your debug patch and have the following to report:

Result of telling Mulberry to file a copy of an outgoing mail into
my Dovecot 'Sent' folder:

Sep 25 17:19:18 zippy dovecot: imap-login: Login: user=<roma>, 
method=PLAIN, rip=192.17.16.93, lip=130.126.113.16, TLS
Sep 25 17:19:25 zippy dovecot: imap(roma): o_stream_sendv() -> EINVAL
Sep 25 17:19:25 zippy dovecot: imap(roma): 
o_stream_send_istream(/var/imap/dovecot/roma/.Sent/tmp/1127686765.P17140Q0M417376.zippy.cso.uiuc.edu) 
failed: Invalid argument

When asking Mulberry to save a draft mail into my Dovecot 'Drafts' folder,
it was a bit more interesting.  Creating a new draft saved just fine.
However, taking an existing draft, editing it and then re-saving it
gave the usual error.  (Note that doing this in Mulberry creates a new
message in the 'Drafts' folder rather than overwriting the earlier draft.)

Anyway, here are the log messages resulting from *this* operation with
a draft.

Sep 25 17:23:28 zippy dovecot: imap-login: Login: user=<roma>, 
method=PLAIN, rip=192.17.16.93, lip=130.126.113.16, TLS
Sep 25 17:23:29 zippy dovecot: imap(roma): o_stream_sendv() -> EINVAL

failed: Invalid argument

Incidentally, as you can tell from the log messages, these are all
maildir folders.  However, I experimented and got the same errors
using mbox folders as well.

Before running these tests I upgraded from -test80 to alpha3.

Hope this helps.  Thanks.
