currently I have one new user with a problem. When she logs in to dovecot with pop3 from her apple mail, dovecot tells problems with the +w permission.

/var/mail is rw by root.mail

Does /var/mail/****** already exist? Do you have a mbox there and Dovecot needs to create a lock file there? If so, try flock.

v2.2 has:

Which locking methods to use for locking mbox. There are four available:

dotlock: Create <mailbox>.lock file. This is the oldest and most

NFS-safe

solution. If you want to use /var/mail/ like directory, the

users

will need write access to that directory.

dotlock_try: Same as dotlock, but if it fails because of permissions or

because there isn't enough disk space, just skip it.

fcntl : Use this if possible. Works with NFS too if lockd is used.

flock : May not exist in all systems. Doesn't work with NFS.

lockf : May not exist in all systems. Doesn't work with NFS.

You can use multiple locking methods; if you do the order they're

declared

in is important to avoid deadlocks if other MTAs/MUAs are using multiple

locking methods as well. Some operating systems don't allow using some

of

them simultaneously.

#mbox_read_locks = fcntl #mbox_write_locks = dotlock fcntl

dotlock will fail in your system.
