X-DOVECOT capabilities
by Timo Sirainen 22 Sep '14

22 Sep '14

Dovecot has a few hidden features currenly, which I know some webmails have been hardcoded to use. Maybe it would be nice to have these available in a bit more globally usable way and advertise some kind of X-DOVECOT capability? I don't really like the idea of having a ton of separate X-DOVECOT-* capabilities. Maybe instead just have X-DOVECOT-1 for the current functionality and when more is added X-DOVECOT-2 etc? Then describe in Dovecot wiki page what they actually contain. Thoughts? The current list of features are at least: - STATUS (X-SIZE): Sum of all RFC822.SIZEs in a mailbox. (More efficient than FETCHing them.) - STATUS (X-GUID): Show mailbox's GUID. - SEARCH X-SAVEDBEFORE, X-SAVEDON, X-SAVEDSINCE: Search with message's saved-timestamp. - FETCH X-SAVEDATE: Fetch message's saved-timestamp. - SEARCH & FETCH X-GUID: Search/fetch message GUID - SEARCH X-MAILBOX, FETCH X-MAILBOX, FETCH X-REAL-UID: With virtual mailboxes search/fetch the mail's physical mailbox name and message UID. - X-CANCEL <tag>: Stop a (long-running) command, which once in a while goes back to the main loop. For example SEARCH or FETCH.

how to solve : Dovecot version mismatch: Master is v2.1.7, lmtp is v2.2.13
by Dave Myers 22 Sep '14

22 Sep '14

Hello again dovecot list ;) I've recently upgraded my dovecot version from 2.1.7 to 2.2.13. both versions where installed from source. I upgraded why attempting to get lmtp working. I ultimately just coped the executable lmtp to the location that dovecot was expecting it to be in. but then the above error appeared. However when I get the info from dovecot I get the following... $ dovecot -n # 2.2.13: /usr/local/etc/dovecot/dovecot.conf so there seems to be an issue somewhere. I should note that I had copied my previous /conf.d/ files and then copied them back after the update. I guess that I have missed a switch during the build, or need to modify a line in the config somewhere that tells what the version is, but that doesn't explain why the dovecot -n returns the correct info, but the error reports something different. I am considering inserting the version_ignore=yes config option, but where should I insert it ? Thanks in advance.

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.

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.

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 ?

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)
