How to use dovecot only as POP3 server / prevent it from creating .imap directories?
by Binarus 18 Sep '20

18 Sep '20

Dear all, on our mail server, I let sendmail deliver incoming messages to a file in mbox format called "inbox" in each user's home directory. Now I would like to use dovecot as POP3 server so that users can let their MUA download their messages via POP3. I do not want to use any IMAP functionality. The POP3 part works with the configuration shown below, but nevertheless there is a problem which is a show stopper: Although I think I have turned off IMAP (e.g. no IMAP listener), dovecot still creates .imap directories and does so in a very weird way. It creates one .imap subdirectory in every subdirectory of each user's home directory, and for every file in each user's home directory creates an additional subdirectory with the same name in its .imap directories. It does this recursively, and 1000 files in a user's home directory would mean 1000 additional subdirectories. Of course, I can't live with that. I know that the dovecot documentation discourages using the home directory as mail location, but in my case this should not be a problem at all if IMAP is not used. I have played around with dovecot for several days, but could not solve that problem. So how can I turn off IMAP completely and prevent dovecot from creating any .imap directories or IMAP related files? This happens with dovecot 2.3.4.1 (f79e8e7e4) on Debian buster (with all updates applied). My configuration (doveconf -n) is (the configuration is complete - I don't use SQL or LDAP): # 2.3.4.1 (f79e8e7e4): /etc/dovecot/dovecot.conf # Pigeonhole version 0.5.4 () # OS: Linux 4.19.0-9-amd64 x86_64 Debian 10.4 # Hostname: host.example.com listen = aaa.bbb.ccc.ddd mail_location = mbox:~:INBOX=~/inbox mail_privileged_group = mail namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { special_use = \Trash } prefix = } passdb { driver = pam } pop3_lock_session = yes protocols = " pop3" service imap-login { inet_listener imap { port = 0 } inet_listener imaps { port = 0 } } service pop3-login { inet_listener pop3 { port = 0 } inet_listener pop3s { port = 995 ssl = yes } } ssl = required ssl_cert = </etc/dovecot/tls/xxxx.crt ssl_cipher_list = DHE-RSA-AES256-GCM-SHA384 ssl_client_ca_dir = /etc/ssl/certs ssl_dh = # hidden, use -P to show it ssl_key = # hidden, use -P to show it ssl_min_protocol = TLSv1.2 ssl_prefer_server_ciphers = yes userdb { driver = passwd } Thank you very much in advance for any idea!

pam dovecot not working with authentication from roundcube
by Ranbir 18 Sep '20

18 Sep '20

Hi Everyone, I made some small changes in my dovecot setup to switch it from looking up users and passwords from a mix of ldap (i.e. freeipa) and password files. One of the changes was to switch from using one id for all authentication to using individual ids) It's working fine with Evolution. I have one account authenticating with GSSAPI, which is my userid for logging into my desktop and for email. The other account in Evolution is logging in using PLAIN and is only used for email (it's shell is set to /sbin/nologin). The problem is with roundcube: I can login with the second, email only account, but my personal ID always errors out. I never use the domain with either one. auth worker: PASSV: pam_sss(dovecot:auth): authentication failure; logname= uid=97 euid=97 tty=dovecot ruser=ranbir rhost=1.2.3.4 user=ranbir auth worker: PASSV: pam_sss(dovecot:auth): received for user ranbir: 17 (Failure setting user credentials) It doesn't matter what user or group I use for unix_listener. If I use 0777 for the mode, I still see the failure and dovecot goes to try the name against the passwd-file, where it obviously fails. This is the pam error: auth-worker(4474): pam(ranbir,1.2.3.4,<oS10hHmv7qkKyAkP>): pam_authenticate() failed: Authentication failure (password mismatch?) What have I misconfigured? Here's the "service auth" section: service auth { chroot = client_limit = 0 drop_priv_before_exec = no executable = auth extra_groups = group = idle_kill = 0 inet_listener { address = 9.8.7.5 haproxy = no port = 17900 reuse_port = no ssl = no } privileged_group = process_limit = 1 process_min_avail = 0 protocol = service_count = 0 type = unix_listener auth-client { group = mode = 0600 user = $default_internal_user } unix_listener auth-login { group = mode = 0600 user = $default_internal_user } unix_listener auth-master { group = mode = 0600 user = } unix_listener auth-userdb { group = mode = 0777 user = $default_internal_user } unix_listener login/login { group = mode = 0666 user = } unix_listener token-login/tokenlogin { group = mode = 0666 user = } user = $default_internal_user vsz_limit = 18446744073709551615 B } Any guidance is appreciated. -- Ranbir

Imaptest using the 'DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA'
by Marc Roos 16 Sep '20

16 Sep '20

I just noticed that the imaptest program is using this default first message 'DON'T DELETE THIS MESSAGE -- FOLDER INTERNAL DATA' of the mbox file to test with. I think this should be execluded, as one does not expect this behaviour.
