Cannot subscribe to Public mailbox
by MI 04 Sep '16

04 Sep '16

I'm trying to set up a Public mailbox, but when I try to subscribe to it in Thunderbird, nothing happens: it doesn't appear as a folder, and when I go back to the Subscribe window, it is unchecked again. I use postfix local dlivery, which created a Maildir when a mail arrived for this mailbox: /home/others/sharedmail/Maildir/{cur,new,tmp} (sharedmail is a system user so that Postfix can deliver the mail; it doesn't have a login shell or a password) To make sure it is not a simple filesystem permissions problem, I did "chmod -R a+rwX Maildir/" This is my current config ( I tried to keep it short by leaving only what might be relevant ): # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 3.2.0-4-amd64 x86_64 Debian 7.9 ... mail_location = maildir:~/Maildir namespace { list = yes location = maildir:/home/others/sharedmail/Maildir prefix = Public. separator = . subscriptions = no type = public } namespace inbox { inbox = yes location = mailbox Drafts { special_use = \Drafts } mailbox ... ... } prefix = separator = . } passdb { driver = pam } plugin { sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap" service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } } userdb { driver = passwd } Also, I'm not sure about the difference between type=public and type=shared. But anyway, I tried both with the same result.

Alternate mail store of few users is disparaged unexpectedly
by Prakash Autade 02 Sep '16

02 Sep '16

Hello, We are using dovecot with mdbox and ALT store on S3(Simple Storage System). We export the mail_location=mdbox:/<user-mailstore>/mdbox:ALT=/altmailstore/<user-mailstore>/mdbox of user in extra parameters. Today, alternate mail store of few users is disparaged unexpectedly which resulted in mail loss. We are unable to trace out why and when the alternate store is disparaged. Our hypothesis is, the folder is removed during doveadm altmove. We want to prevent this in future. It will be great if someone helps to identify the root cause. Dovecot version: 2.2.19 # dovecot -n # 2.2.19: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-573.el6.x86_64 x86_64 CentOS Linux release 6.0 (Final) auth_mechanisms = plain login auth_verbose_passwords = plain disable_plaintext_auth = no mail_fsync = always mail_gid = 65111 mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " quota" mail_uid = 65111 mdbox_rotate_interval = 1 days mdbox_rotate_size = 20 M mmap_disable = yes namespace inbox { inbox = yes location = mailbox Drafts { auto = create special_use = \Drafts } mailbox Junk { special_use = \Junk } mailbox Sent { special_use = \Sent } mailbox "Sent Items" { auto = create } mailbox "Sent Messages" { special_use = \Sent } mailbox Trash { auto = create special_use = \Trash } mailbox chat { auto = create } prefix = INBOX. separator = . type = private } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } ssl_cert = </conf/server/server.crt ssl_key = </conf/server/server.key -- Sincerely, Prakash P.

Dovecot 2.2.25 fails on SSL
by Andreas M. Kirchwitz 02 Sep '16

02 Sep '16

Dear Dovecot developers! This problem already existed some years ago, has been fixed, and now it's there again in Dovecot 2.2.25 (2.2.24 was fine). I'm running CentOS 6 with a custom OpenSSL installation in /usr/local/ssl Therefore, Dovecot is configured like this: env SSL_CFLAGS="-I/usr/local/ssl/include" SSL_LIBS="-L/usr/local/ssl/lib -Wl,-R/usr/local/ssl/lib -lcrypto -lssl" ./configure --prefix=/usr/local/Dovecot-2.2.25 --with-ssl=openssl --with-ssldir=/usr/local/Dovecot-2.2.25/etc/dovecot/certs With "pkg-config", the same options for SSL are provided. "make" and "make install" run just fine, and the daemon starts without any errors. However, if a user connects on port 993 (IMAPS), Dovecot logs this failure message to syslog: Jul 4 01:08:43 myhost dovecot: ssl-params: Fatal: Couldn't load required plugin /usr/local/Dovecot-2.2.25/lib/dovecot/libssl_iostream_openssl.so: dlopen() failed: libcrypto.so.1.0.0: cannot open shared object file: No such file or directory Jul 4 01:08:43 myhost dovecot: ssl-params: Error: child process failed with status 22784 ldd /usr/local/Dovecot-2.2.25/lib/dovecot/libssl_iostream_openssl.so linux-gate.so.1 => (0x00e8c000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found librt.so.1 => /lib/librt.so.1 (0x00be4000) libc.so.6 => /lib/libc.so.6 (0x001a6000) libpthread.so.0 => /lib/libpthread.so.0 (0x003e4000) /lib/ld-linux.so.2 (0x007e7000) ldd /usr/local/Dovecot-2.2.25/lib/dovecot/libdcrypt_openssl.so linux-gate.so.1 => (0x00dca000) libcrypto.so.1.0.0 => not found libssl.so.1.0.0 => not found librt.so.1 => /lib/librt.so.1 (0x00a7a000) libc.so.6 => /lib/libc.so.6 (0x00160000) libpthread.so.0 => /lib/libpthread.so.0 (0x0072f000) /lib/ld-linux.so.2 (0x00560000) When comparing to Dovecot 2.2.24: ldd /usr/local/Dovecot-2.2.24/lib/dovecot/libssl_iostream_openssl.so linux-gate.so.1 => (0x0073d000) libcrypto.so.1.0.0 => /usr/local/ssl/lib/libcrypto.so.1.0.0 (0x00b04000) libssl.so.1.0.0 => /usr/local/ssl/lib/libssl.so.1.0.0 (0x0044a000) librt.so.1 => /lib/librt.so.1 (0x00a60000) libc.so.6 => /lib/libc.so.6 (0x001e5000) libdl.so.2 => /lib/libdl.so.2 (0x003a9000) libpthread.so.0 => /lib/libpthread.so.0 (0x009d0000) /lib/ld-linux.so.2 (0x00d77000) There's no libdcrypt_openssl.so in Dovecot 2.2.24, so I guess with the newly introduced dcrypt stuff something with SSL went wrong. Would be great if that could be fixed so that SSL works again. Thanks a lot in advance ... Andreas

Force SSL/TLS and client certificate checking only for connections from Internet
by Konstantin Khomoutov 02 Sep '16

02 Sep '16

(Please CC me if possible.) I have Dovecot 2.2.13 (shipped with Debian 8 "Jessie") serving IMAP for a small organization. It's connected both to the Internet and to that organization LAN. I'd like to have Dovecot has rather tight security requirements for connections made from the Internet and reasonably laxed requirements for the LAN clients. Due to Dovecot authenticating users against a LDAP database which is also used for logging into the users' machines, we have to use somewhat weak passwords (randomly generated but short) for most users. Because of this I want to: * Mandate the usage of TLS for the connections made from Internet; * Require the clients to present their SSL certificates, and * Verify the validity of these certificates. The certificates are issued by our own CA, so it's not a problem to verify them. The first iteration was to set ssl = required and disable_plaintext_auth = yes which I then overrode with a "remote" section for LAN connections: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes } The next iteration was to actually enable verification of the client certificates. I have set the "ssl_ca" variable appropriately, then ssl_require_crl = yes ssl_verify_client_cert = yes and auth_ssl_require_client_cert = yes Then I went on and attempted to override the latter two settings for the LAN clients by appending them to my special "remote" section to it read: remote 192.168.0.0/16 { disable_plaintext_auth = no ssl = yes ssl_verify_client_cert = no auth_ssl_require_client_cert = no } But after restart Dovecot complained that I cannot use the "auth_ssl_require_client_cert" setting in a "remote" section. I have removed it in the hope that still having ssl_verify_client_cert = no there would inhibit SSL certificate checks for the LAN clients but apparently it did not. So, to recap: * I need to have tight TLS settings for the clients connecting from the Internet: - TLS is required; - The client must present a valid certificate (issued by a CA we control). * LAN clients should use relaxed security settings: TLS is okay but that's all. How do I go about setting this? (On a side note, I can supposedly get away installing stunnel and making it proxy IMAP and IMAPS connections to Dovecot -- at least from the documentation, it appears stunnel supports IMAP+STARTTLS, -- but I would rather have all this handled solely by Dovecot.)

Debian Jessie comes with systemd so you really should not use initscript anymore but switch to systemd for starting dovecot. There is systemd service description file available for you in case your vendor does not provide it in the package: https://github.com/dovecot/core/blob/master/dovecot.service.in Sami
