Hi Magnus,

I had to install a second mailserver and managed to get things to work on that server and after that on the first server. I did a number things different and didn't care to isolate the cause.

I'll tell you the differences I made to get things to work. I now use LDA cvs snapshot from 13 may and dovecot-1.0beta8 So try that combination. I also made differences to dovecot.conf. Check you have your sections right defined. I use all settings from the wiki LDA page. I have config files attached as an example for you.

# If you need to set multiple mailbox locations or want to change default # namespace settings, you can do it by defining namespace sections: # # You can have private, shared and public namespaces.

Shared namespaces are meant for user-owned mailboxes which are # shared to other users, while public namespaces are for more globally # accessible mailboxes. # # REMEMBER: If you add any namespaces, the default namespace must be added # explicitly, ie. default_mail_env does nothing unless you have a namespace # without a location setting. Default namespace is simply done by having a # namespace with empty prefix. #namespace private { # Hierarchy separator to use. You should use the same separator for all # namespaces or some clients get confused. '/' is usually a good one. # separator = /

# Maximum allowed length for mail keyword name. It's only forced when trying # to create new keywords. #mail_max_keyword_length = 50

# Save mails with CR+LF instead of plain LF.

# Use mmap() instead of read() to read mail files. read() seems to be a bit # faster with my Linux/x86 and it's better with NFS, so that's the default. # Note that OpenBSD 3.3 and older don't work right with mail_read_mmaped = yes. #mail_read_mmaped = no

# Copy mail to another folders using hard links. This is much faster than # actually copying the file.

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.

# When mbox changes unexpectedly we have to fully read it to find out what # changed. If the mbox is large this can take a long time. Since the change # is usually just a newly appended mail, it'd be faster to simply read the # new mails. If this setting is enabled, Dovecot does this but still safely # fallbacks to re-reading the whole mbox file whenever something in mbox isn't # how it's expected to be.

# "prefetch" user database means that the passdb already provided the # needed information and there's no need to do a separate userdb lookup. # This can be made to work with SQL and LDAP databases, see their example # configuration files for more information how to do it. # http://wiki.dovecot.org/AuthSpecials #userdb prefetch { #}

# User to use for the process. This user needs access to only user and # password databases, nothing else. Only shadow and pam authentication # requires roots, so use something else if possible. Note that passwd # authentication with BSDs internally accesses shadow files, which also # requires roots. Note that this user is NOT used to access mails. # That user is specified by userdb above. user = root

# Directory where to chroot the process. Most authentication backends don't # work if this is set, and there's no point chrooting if auth_user is root. # Note that valid_chroot_dirs isn't needed to use this setting. #chroot =

# Number of authentication processes to create #count = 1

# Require a valid SSL client certificate or the authentication fails. #ssl_require_client_cert = no

# Take the username from client's SSL certificate, using X509_NAME_oneline() # which typically uses subject's Distinguished Name. #ssl_username_from_cert = no socket listen { master { path = /var/run/dovecot/auth-master mode = 0666 user = vmail # User running Dovecot LDA #group = mail # Or alternatively mode 0660 + LDA user in this group } }

# It's possible to export the authentication interface to other programs, # for example SMTP server which supports talking to Dovecot. Client socket # handles the actual authentication - you give it a username and password # and it returns OK or failure. So it's pretty safe to allow anyone access to # it. Master socket is used to a) query if given client was successfully # authenticated, b) userdb lookups.

# listener sockets will be created by Dovecot's master process using the # settings given inside the auth section #auth default_with_listener { # mechanisms = plain # passdb pam { # } # userdb passwd { # } # socket listen { # master { # path = /var/run/dovecot-auth-master # # WARNING: Giving untrusted users access to master socket may be a # # security risk, don't give too wide permissions to it! # #mode = 0600 # # Default user/group is the one who started dovecot-auth (root) # #user = # #group = # } # client { # path = /var/run/dovecot-auth-client # mode = 0660 # } # } #}

# connect sockets are assumed to be already running, Dovecot's master # process only tries to connect to them. They don't need any other settings # than path for the master socket, as the configuration is done elsewhere. # Note that the client sockets must exist in login_dir. #auth external { # socket connect { # master { # path = /var/run/dovecot-auth-master # } # } #}
