Hello all.

I appreciate the responses to my problem on v0.99.14. Thank you all.

We have built a new server running version 1.0-0_15.beta9.el4. The mail delivery agent is sendmail. We seem to have gotten it up fairly easily. But we have one problem. We are using the maildir feature instead of mbox and when ever mail gets delivered, it is not sending it to the \maildir\new folder. It seems to be dumping it in the root of the maildir directory, thus when a client checks for email, it appears nothing is there.

Here is a sample from our config. Any suggestions will be much appreciated. Forgive me if this is elementary question, but I am new to dovecot.

## Mailbox locations and namespaces

# Default MAIL environment to use when it's not set. By leaving this empty

# dovecot tries to do some automatic detection as described in

# doc/mail-storages.txt. There are a few special variables you can use, eg.:

# %u - username

# %n - user part in user@domain, same as %u if there's no domain

# %d - domain part in user@domain, empty if there's no domain

# %h - home directory

# See doc/variables.txt for full list. Some examples:

# default_mail_env = maildir:/var/mail/%1u/%u/Maildir

# default_mail_env = mbox:~/mail/:INBOX=/var/mail/%u

# default_mail_env = mbox:/var/mail/%d/%n/:INDEX=/var/indexes/%d/%n

default_mail_env = maildir:/home/%u/Maildir

# 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. The only difference

# between them is how Dovecot announces them to client via NAMESPACE

# extension. 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 = /

# Prefix required to access this namespace. This needs to be different for

# all namespaces. For example "Public/".

#prefix =

# Physical location of the mailbox. This is in same format as

# default_mail_env, which is also the default for it.

#location =

# There can be only one INBOX, and this setting defines which namespace

# has it.

#inbox = yes

# If namespace is hidden, it's not advertised to clients via NAMESPACE

# extension or shown in LIST replies. This is mostly useful when converting

# from another server with different namespaces which you want to depricate

# but still keep working. For example you can create hidden namespaces with

# prefixes "~/mail/", "~%u/mail/" and "mail/".

#hidden = yes

# Grant access to these extra groups for mail processes. Typical use would be

# to give "mail" group write access to /var/mail to be able to create dotlocks.

#mail_extra_groups =

# Allow full filesystem access to clients. There's no access checks other than

# what the operating system does for the active UID/GID. It works with both

# maildir and mboxes, allowing you to prefix mailboxes names with eg. /path/

# or ~user/.

#mail_full_filesystem_access = no

That's not a dovecot thing, that's a procmail thing (these are from FC1 but I think they're still the same): --> Configure procmail # Change the location where sendmail/procmail delivers mail.

Hello, In an effort to help I have a couple of questions regarding your environment. First, I guess I should preface this by indicating that I needed to make 0 (zero) path indicators/ pointers to maildirs in the dovecot.conf file to make dovecot work correctly. I run with the majority of users as actual users on the system. Those that are virtual are aliased in sendmail. I run everything out of a MySQL database in an effort to make any moves/ changes as simple as backing up the DB > moving/ changing-mail-system and re-initializing the mail system. That said; I (as you) run sendmail as the MTA. Oh, I also manage/ run webmail to handle the virtual users out of the DB (actual users as well). OK, on to your delemna, as you undoubtedly already know, on most *NIX systems sendmail keeps users mail in /var/mail/<user-name> mail that is en-route is in /var/spool/mqueue or /var/spool/clientmqueue using maildomain as localhost permits keeping sendmail/imap(s)/pop(3) happy with users <default> mail in ~/<username> (/usr/home/<username>. In my experience with dovecot automatically creating a mail folder/ directory in the users folder/ directory as part of the user creation process makes dovecot quite happy. As dovecot then creates (for imap(s)) a .imap folder in the /home/<username>/mail folder - eg; /home/<username>/mail/.imap in that folder, dovecot also creates: (again, for imap(s)) INBOX, and inside of that: dovecot.index, dovecot.index.cache, and dovecot.index.log. I don't mean to have sounded condecending in this approach to explaining all this. But chose to keep it as simple and concice as possible for the sake of _clarity_. Note: all this was accomplished _without_ making _any_ pointers in dovecot.conf *other* than SSL, logging and dovecot permissions (note the omission of any mail folder related settings). From my dovecot.conf: # Protocols we want to be serving: # imap imaps pop3 pop3s # protocols = imap pop3 protocols = imaps # protocol imap { # listen = *:10143 # ssl_listen = *:10943 # .. # } # protocol pop3 { # listen = *:10100 # .. # } listen = *:993 # Disable SSL/TLS support. ssl_disable = no ssl_cert_file = /etc/ssl/certs/dovecot.pem #ssl_key_file = /etc/ssl/private/dovecot.pem # Request client to send a certificate. ssl_verify_client_cert = no #ssl_parameters_regenerate = 168 ssl_parameters_regenerate = 0 (the above line can *really* affect performance, as regeneration is *very* CPU intensive. A setting of 0 (zero) requires regeneration only on startup) # SSL ciphers to use ssl_cipher_list = ALL:!LOW shutdown_clients = yes log_path = /var/log/dovecotlog (The line above can *really* help you here, as it can emit possible pointers, as to what might be causing your undesired results - this line should be MANDITORY) log_timestamp = "%b %d %H:%M:%S " (the above line will also be a pointer) # Directory where authentication process places authentication # UNIX sockets which login needs to be able to connect to. # The sockets are created when running as root, so you don't # have to worry about permissions. Note that everything in this # directory is deleted when Dovecot is started. login_dir = /var/run/dovecot/login (Do you have this line?) # chroot login process to the login_dir. Only reason not # to do this is if you wish to run the whole Dovecot # without roots. http://wiki.dovecot.org/Rootless login_chroot = yes (and this one?) # User to use for the login process. Create a completely # new user for this, and don't use it anywhere else. # The user must also belong to a group where only it has # access, it's used to control access for authentication process. # Note that this user is NOT used to access mails. # http://wiki.dovecot.org/UserIds login_user = dovecot # Set max. process size in megabytes. If you don't use # login_process_per_connection you might need to grow this. login_process_size = 64 (Line above depends on the average size of your userbase/ workload) # Should each login be processed in it's own process (yes), # or should one login process be allowed to process multiple # connections (no)? Yes is more secure, espcially with # SSL/TLS enabled. No is faster since there's no need # to create processes all the time. #login_process_per_connection = yes login_process_per_connection = no # Greeting message for clients. login_greeting = IMAP server ready. (or just for fun: login_greeting = Big brother's watching you.) # Space-separated list of elements we want to log. # The elements which have a non-empty variable # value are joined together to form a comma-separated # string. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c (This line above, can also assist you in DEBUGING problems) login_log_format = %$: %s (again, also a helpful DEBUG tool) # Maximum number of running mail processes. # When this limit is reached, # new users aren't allowed to log in. max_mail_processes = 1024 # Show more verbose process titles (in ps). # Currently shows user name and IP address. # Useful for seeing who are actually using # the IMAP processes (eg. shared mailboxes # or if same uid is used for multiple accounts). verbose_proctitle = yes (Need more information?) # Show protocol level SSL errors. verbose_ssl = no first_valid_uid = 500 #last_valid_uid = 0 first_valid_gid = 0 #last_valid_gid = 0 # Grant access to these extra groups for mail # processes. Typical use would be to give "mail" # group write access to /var/mail to be able to # create dotlocks. mail_extra_groups = mail (Here is an important setting! What's yours look like?) # Support for dynamically loadable plugins. # mail_plugins is a space separated list of plugins # to load. # mail_plugins = convert,imap_quota,zlib,trash mail_plugin_dir = /usr/local/lib/dovecot/imap ## ## POP3 specific settings ## protocol pop3 { pop3_uidl_format = %08Xu%08Xv pop3_client_workarounds = outlook-no-nuls oe-ns-eoh } auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ (The above line probably wrapped in your mail reader (client) it should be ONE long line without a break) auth_verbose = yes auth_worker_max_count = 30 userdb passwd { } # 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 I've left out some of the lines in my conf. But they didn't really apply to your situation anyway. I hope my experience will help jumpstart your setup. Best wishes, Chris H. Quoting Patrick Carney :

Correction. Yes it should be /home/Patrick/Maildir/new/

My mistake. Yes it is a sendmail problem.

Tell us the exact path where the mail ends up since \maildir\new is NOT a Unix file path.

Mail should be delivered to /home/patrick/Maildir/new/

If it is not ending there, it's Sendmail problem, not Dovecot.

[snip]

| # | | default_mail_env = maildir:/home/%u/Maildir

Wherever the mail ends, you can fix that default_mail_env to get it....

Let's know where Sendmail delivers the mail (I mean the directory path).
