dovecot´s multiple quota roots
by Andreas Kasenides 22 Sep '14

22 Sep '14

I am trying to find out how Dovecot behaves when there are multiple quota roots. I could not find something authoritative on this. For example, on a nicely running server that used fs quota I now have in 90-quota.conf > plugin { > quota = fs:Mail Quota:user:mount=/Mail > quota2 = maildir:Mail User Quota > } When I do > > doveadm quota get -u atrige01 > Quota name Type Value Limit > % > Mail Quota STORAGE 80036 204800 > 39 > Mail User Quota STORAGE 79306 - > 0 > Mail User Quota MESSAGE 304 - > 0 Apparently both STORAGE quotas values are the same. The question is which of the two is being used by Dovecot. If I insert a limit on the maildir quota which of the two will be used? I am using Dovecot 2.2.12. thank you

numeric username

Heya, does dovecot support "numeric only" usernames (in format "^0-9+$")? We are unable to deliver emails to such usernames via LMTP: Sep 22 08:41:05 razor4 postfix/lmtp[2120]: D4FD91CDC11F: to=<231588(a)example.org>, relay=example.org[private/dovecot-lmtp], delay=217653, delays=217653/0.01/0.02/0, dsn=4.2.0, status=deferred (host example.org[private/dovecot-lmtp] said: 451 4.2.0 <231588(a)example.org> Permission denied (in reply to end of DATA command)) On normal username format (^[a-z][-a-z0-9]+$) everything is working fine. Permissions are the same as on other accounts: # ls -la .mailbox -rw-------+ 1 231588 users 0 Sep 19 20:13 .mailbox Using dovecot 2.2.13 with local accounts on RHEL and (relevant) configs: auth_username_chars = abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ01234567890.-_@ auth_username_format = %Ln auth_username_translation = ... lmtp_address_translate = ... passdb { args = cache_key=%u%s dovecot default_fields = deny = no driver = pam master = no name = override_fields = pass = no result_failure = continue result_internalfail = continue result_success = return-ok skip = never } ... service lmtp { chroot = client_limit = 1 drop_priv_before_exec = no executable = lmtp extra_groups = group = idle_kill = 0 privileged_group = process_limit = 0 process_min_avail = 5 protocol = lmtp service_count = 0 type = unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } unix_listener lmtp { group = mode = 0666 user = } user = vsz_limit = 18446744073709551615 B } .... userdb { args = default_fields = driver = passwd name = override_fields = result_failure = continue result_internalfail = continue result_success = return-ok skip = never } Thank you in advance, cheers, Jernej

I was able to decipher the error after looking at some other web pages. I found I have to compile using the openldap libraries instead of the default Solaris ldap libraries. I compiled using the following: > LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ > ./configure --prefix=/tmp/tocevod --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes ldd on the ....libexec/dovecot/auth files shows the proper openldap libraries. libdovecot.so.0 => /usr/local/tools/dovecot/lib/dovecot/libdovecot.so.0 libpam.so.1 => /usr/lib/libpam.so.1 libldap-2.4.so.2 => /usr/local/openldap/lib/libldap-2.4.so.2 libsasl.so.1 => /usr/lib/libsasl.so.1 libssl.so.0.9.7 => /usr/sfw/lib/libssl.so.0.9.7 libcrypto.so.0.9.7 => /usr/sfw/lib/libcrypto.so.0.9.7 liblber-2.4.so.2 => /usr/local/openldap/lib/liblber-2.4.so.2 libresolv.so.2 => /usr/lib/libresolv.so.2 libgen.so.1 => /usr/lib/libgen.so.1 librt.so.1 => /usr/lib/librt.so.1 libnsl.so.1 => /usr/lib/libnsl.so.1 libsocket.so.1 => /usr/lib/libsocket.so.1 libsendfile.so.1 => /usr/lib/libsendfile.so.1 libc.so.1 => /usr/lib/libc.so.1 libgcc_s.so.1 => /usr/sfw/lib/libgcc_s.so.1 libcmd.so.1 => /usr/lib/libcmd.so.1 libmd.so.1 => /usr/lib/libmd.so.1 libaio.so.1 => /usr/lib/libaio.so.1 libmp.so.2 => /usr/lib/libmp.so.2 libscf.so.1 => /usr/lib/libscf.so.1 libdoor.so.1 => /usr/lib/libdoor.so.1 libuutil.so.1 => /usr/lib/libuutil.so.1 libssl_extra.so.0.9.7 => /usr/sfw/lib/libssl_extra.so.0.9.7 libcrypto_extra.so.0.9.7 => /usr/sfw/lib/libcrypto_extra.so.0.9.7 libm.so.2 => /usr/lib/libm.so.2 I am not able to authenticate to my ldap server.

Thank you all for your assistance. I was able to locate another web site that mentioned I needed to compile dovecot with my openldap libraries. I then compiled dovecot in the following manner: CPPFLAGS=-I/usr/local/openldap/include \ LDFLAGS='-L/usr/local/openldap/lib -R/usr/local/openldap/lib' \ ./configure --prefix=/tmp/tocevod --with-ssl=openssl --with-solr --with-zlib --with-bzlib --with-ldap=yes This then included the openldap libraries. I tested access and now it works. ldd on /dovecot/libexec/dovecot/auth showed the openldap libraries. libdovecot.so.0 => /usr/local/tools/dovecot/lib/dovecot/libdovecot.so.0 libpam.so.1 => /usr/lib/libpam.so.1 libldap-2.4.so.2 => /usr/local/openldap/lib/libldap-2.4.so.2 libsasl.so.1 => /usr/lib/libsasl.so.1 libssl.so.0.9.7 => /usr/sfw/lib/libssl.so.0.9.7 libcrypto.so.0.9.7 => /usr/sfw/lib/libcrypto.so.0.9.7 liblber-2.4.so.2 => /usr/local/openldap/lib/liblber-2.4.so.2 libresolv.so.2 => /usr/lib/libresolv.so.2 libgen.so.1 => /usr/lib/libgen.so.1 librt.so.1 => /usr/lib/librt.so.1 libnsl.so.1 => /usr/lib/libnsl.so.1 libsocket.so.1 => /usr/lib/libsocket.so.1 libsendfile.so.1 => /usr/lib/libsendfile.so.1 libc.so.1 => /usr/lib/libc.so.1 libgcc_s.so.1 => /usr/sfw/lib/libgcc_s.so.1 libcmd.so.1 => /usr/lib/libcmd.so.1 libmd.so.1 => /usr/lib/libmd.so.1 libaio.so.1 => /usr/lib/libaio.so.1 libmp.so.2 => /usr/lib/libmp.so.2 libscf.so.1 => /usr/lib/libscf.so.1 libdoor.so.1 => /usr/lib/libdoor.so.1 libuutil.so.1 => /usr/lib/libuutil.so.1 libssl_extra.so.0.9.7 => /usr/sfw/lib/libssl_extra.so.0.9.7 libcrypto_extra.so.0.9.7 => /usr/sfw/lib/libcrypto_extra.so.0.9.7 libm.so.2 => /usr/lib/libm.so.2 Thanks again.

dovecot doesn't see my mails ?
by Dave Myers 19 Sep '14

Dear dovecot users. I have an odd issue in that when I connect to my dovecot server from either a local or remote system I can't see my test emails (I have the impression that is is looking at the wrong location on disk). here are some details.... # dovecot -n # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_gid = 1002 mail_home = /var/mail/virtual/%d/%n mail_location = maildir:~/mail/: mail_uid = 1002 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 { args = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-client { mode = 0660 user = mail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } userdb { driver = passwd } verbose_ssl = yes when I connect (via openSSL from a remote system) openssl s_client -connect mail.exsportee.biz:993 CONNECTED(00000003) depth=0 C = fr, ST = coupvray, L = paris, O = exsportee, OU = facilitee, CN = scibearspace, emailAddress = david.myers(a)scibearspace.org verify error:num=18:self signed certificate verify return:1 depth=0 C = fr, ST = coupvray, L = paris, O = exsportee, OU = facilitee, CN = scibearspace, emailAddress = david.myers(a)scibearspace.org verify return:1 [.... security stuff removed....] * OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE AUTH=PLAIN AUTH=LOGIN AUTH=CRAM-MD5] Dovecot ready. auth login "websales(a)exsportee.biz" "testPassword" auth OK [CAPABILITY IMAP4rev1 LITERAL+ SASL-IR LOGIN-REFERRALS ID ENABLE IDLE SORT SORT=DISPLAY THREAD=REFERENCES THREAD=REFS MULTIAPPEND UNSELECT CHILDREN NAMESPACE UIDPLUS LIST-EXTENDED I18NLEVEL=1 CONDSTORE QRESYNC ESEARCH ESORT SEARCHRES WITHIN CONTEXT=SEARCH LIST-STATUS SPECIAL-USE] Logged in a list "" "*" * LIST (\HasNoChildren) "."

Support of unicode in then recipient names
by Александр Егоров 19 Sep '14

19 Sep '14

Hi Dovecot Community, We are using ltmp to deliver messages through postfix to dovecot. During testing we have found that dovecot does not understand recipient email address if it is composed from national symbols : e.g. ยจฆฟคฏข(a)xn--22cdfh1b8fsa.xn--22cdfh1b8fsa Question is are there any plans to either add native support for such email addresses or to translate it to punycode and then try to find such a recipient? -- Александр Егоров (Alexander Yegorov)

Syslog PID

Hi! How to write PIDs to syslog? Example: Sep 19 00:57:00 hostname dovecot: pop3-login: Login: user=< username(a)domainname.com >, method=PLAIN, rip=XXX.XXX.XXX.XXX, lip=XXX.XXX.XXX.XXX, mpid=14407, TLS, session=<6LYlcmYDAQC4reGs> Sep 19 00:57:00 hostname dovecot: pop3( username(a)domainname.com ): Disconnected: Logged out top=0/0, retr=0/0, del=0/0, size=0 Sep 19 00:57:09 hostname exim[14423]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front) Sep 19 00:57:09 hostname exim[14424]: 2014-09-19 00:57:09 dovecot_login authenticator failed for s16010629.onlinehome-server.info (User) [82.165.16.9]: 535 Incorrect authentication data (set_id=front I need it because i write all logs to postgresql and analyze them with Adiscon LogAnalyzer. Perhaps, per-process logs entry with PID would be better.

unable to see mail when using telnet / open ssl
by Dave Myers 19 Sep '14

19 Sep '14

Dear dovecot list. I'm setting up my own VPS and working through getting mail to work. Here is my dovecot -n $dovecot -n maildir:%h/%d/%n/mail : layout=fs # 2.1.7: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-5-xen-amd64 x86_64 Debian 6.0.3 auth_debug = yes auth_debug_passwords = yes auth_mechanisms = plain login cram-md5 auth_verbose = yes auth_verbose_passwords = plain lda_mailbox_autocreate = yes log_path = /var/log/dovecot.log mail_debug = yes mail_gid = 1002 mail_home = /var/mail/virtual/%d/%n mail_location = maildir:~/mail: layout=fs mail_uid = 1002 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 { args = scheme=SHA512-CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } protocols = imap service auth { unix_listener auth-client { mode = 0660 user = mail } } service imap-login { inet_listener imap { port = 143 } inet_listener imaps { port = 993 ssl = yes } } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { args = username_format=%u /etc/dovecot/users driver = passwd-file } userdb { driver = passwd } verbose_ssl = yes I can successfully log into dovecot using telnet and open ssl from a remote terminal, so authentication and everything is working fine. From the above dovecot -n I asume that mails should be going to /var/mail/virtual/domain/user/mail However when I view this directory I can see a number of test mails that I have sent using echo "Hello me" | mail -s "Dovecot test" $USER (see http://wiki2.dovecot.org/FindMailLocation) Why am I not seeing them when I use telnet / openSSL to log in? All help is greately appreciated. -- Tel: + 33 6 50 14 39 34 email: david.myers.24j74(a)gmail.com Addres: 22 Rue de L'Eglise 77700 Coupvray. 77700 France
