[Dovecot] question regarding rw-access on mailbox on creation/login (dovecot 1.2.17)
Hi,
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.
Error: open(/var/mail/******) failed: Permission denied (euid=3462(******) egid=548(dozenten) missing +w perm: /var/mail)
/var/mail is rw by root.mail
I cant see why just this particular user has that problem/gets that messages.
AFAIK no one changed any default permissions on directories or set different users.
What could be "wrong"? Any suggestions is welcome.

Filesystem ACLs?

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.

Do the other users have "mail" as secondary group?

Thanks for all suggestions!
"mail_privileged_group = mail" did the magic.I'v read the V1.0 -> 1.1 -> 1.2, but did not read ALL config options in the new dovecot.conf.
