Sieve with plussed delivery / 'seen flag'?

this is similar to Bug 3695 ( ).

I use "lmtp_fuzzy_mailbox_match: 1".

Delivery (to a plus or simple address) is proceeded first by 
imap/lmtpd.c:deliver_local() and then by deliver_mailbox().  I found 
out, that when I use an address without plus, the 7th parameter passed 
to deliver_mailbox is "username" (owner of the mailbox), and 
mydata->authuser (which was NULL in my tests) otherwise.

This leads later to a call of imap/append.c:append_setseen().  If 
username was passed as 7th argument to deliver_mailbox (no 
plus-address), as->internalseen is true in that function and the message 
is marked as \\Seen.  Otherwise internalseen is false and the message 
does not appear as \\Seen.  I have no investigated what as->seen_seq 
does or is supposed to do.

This patch fixes the problem on my system (addr+Sent is resolved during 
fuzzy-matching), but I don't know if it causes any side effects.
