Hello.

I've tried to implement dovecot's deliver LDA to my home mailserver.

I've run into troubles :)

dovecot-deliver.conf: -- snip -- mail = maildir:%h/Maildir:INBOX=maildir:%h/Maildir mbox_read_locks = flock mbox_write_locks = flock -- snip --

when i run:

deliver -d bfg < email.txt dovecot delivers message to ~/Maildir/maildir/new

It acctually creates "maildir" folder inside real maildir folder.

If i try to list messages via Outlook express mail client, OE reports entire folder list, but also lists one message "which no longer exists on server".

If i remove ~/Maildir/maildir folder this message dissaperas from OE imap folder listing.

Test scenario:

1. start dovecot
2. try to deliver message using "deliver" program (succeedes)
3. try to open INBOX via imap:

Outlook Express:

• reports INBOX message listing with one message, which "doesn't exist on server anymore"
• the next delivery test with "deliver" LDA fails (lots of nanosleep() calls)

Thunderbird:

• reports that there are NO messages in INBOX
• still can delivery messages with "deliver" LDA

deliver strace output (search for EVIL CODE string):
