Trying to regain access to my email archive after an upgrade.
by Rick Jones 27 Sep '16

27 Sep '16

Hi - I had been running an Ubuntu 12.04 system on which I receive email, with an inbox in /var/mail/ and a bunch of folders under ~/Maildir. When I upgraded from 14.04 there were a bunch of questions about keeping old/new config files and my muddling through it has me seeing only the inbox, and then a Drafts, Sent and Trash Folder. I would like to regain access to the messages stored under ~/Maildir, but have been thoroughly unsuccessful. I seem to run into duplicate prefix issues and I suspect I have other issues, when I try to add: namespace rest { separator = / prefix = location = maildir:~/Maildir } to what is already present. I've seen a few of the wiki pages, but not fully understanding what is going-on I'm afraid I've not groked them terribly well. any help/pointers for this cluser would be much appreciated. rick jones raj@tardy:~$ dovecot --version 2.2.9 raj@tardy:~$ dovecot -n # 2.2.9: /etc/dovecot/dovecot.conf doveconf: Warning: NOTE: You can get a new clean config file with: doveconf -n > dovecot-new.conf doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:25: 'imaps' protocol is no longer necessary, remove it doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:732: protocol managesieve {} has been replaced by protocol sieve { } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:904: add auth_ prefix to all settings inside auth {} and remove the auth {} section completely doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:942: passdb pam {} has been replaced by passdb { driver=pam } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:1055: userdb passwd {} has been replaced by userdb { driver=passwd } doveconf: Warning: Obsolete setting in /etc/dovecot/dovecot.conf:1117: auth_user has been replaced by service auth { user } # OS: Linux 3.13.0-95-generic x86_64 Ubuntu 14.04.5 LTS auth_mechanisms = plain login log_timestamp = "%Y-%m-%d %H:%M:%S " mail_location = mbox:~/mail:INBOX=/var/mail/%u 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 } passdb { driver = pam } protocols = imap service auth { user = root } ssl_cert = </etc/dovecot/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd } userdb { driver = passwd } protocol pop3 { pop3_uidl_format = %08Xu%08Xv } raj@tardy:~$ vi /etc/dovecot/conf.d/15-mailboxes.conf raj@tardy:~$ dovecot --version 2.2.9

imapc fetch optimization
by Nagy, Attila 27 Sep '16

27 Sep '16

Hi, imapc does a lot of UID FETCH $UID (BODY.PEEK[]), which is nice, because it works even with the dumbest IMAP server, altough it really kills performance, especially on high latency lines. I wonder: if IMAP servers can effectively handle boundless fetches (like a list with all wanted UIDs, or simply 1:* if all are needed), do you see this as a good addition to develop? This could be a new imapc_features setting afterall... Thanks,

Drac Plugin
by Darryl Baker 27 Sep '16

27 Sep '16

I now have the drac plugin compiled and working. The plugin binary might even work with the Debian/Ubuntu binary. It was a one line change. I need to talk to the sendmail folks about their macro for the DRAC feature. My custom sendmail.cf code works in a way that makes using drac and SpamHaus for anyone on a blacklisted IP such as non-comercial Comcast users. I am hoping that the drac plugin will get fixed in the core distribution and possible the new binary make it into the Debian/Ubuntu binary build. *** dovecot-2.2.22/src/plugins/drac/drac-plugin.c 2016-09-23 22:49:56.345568783 -0500 --- dovecot-2.2.22/src/plugins/drac/drac-plugin.c-orig 2016-09-26 14:33:46.828670909 -0500 *************** *** 25,31 **** /* libdrac function */ int dracauth(char *, unsigned long, char **); ! const char *drac_plugin_version = DOVECOT_ABI_VERSION; static struct timeout *to_drac = NULL; static const char *drachost = NULL; /* dracd host */ --- 25,31 ---- /* libdrac function */ int dracauth(char *, unsigned long, char **); ! const char *drac_plugin_version = DOVECOT_VERSION; static struct timeout *to_drac = NULL; static const char *drachost = NULL; /* dracd host */ *Darryl Baker*

I am asking becaus I have another user, for which I migrated the format to mdbox, for which I have these folders (curr, tmp, new) but also the structure I have for the shared :s. Are both formats mixed for that user?

Shared mailboxes nightmare (for me :-( )
by Felix Rubio Dalmau 26 Sep '16

26 Sep '16

Hi everybody, I am honestly desperate: I have spent/invested the whole day in trying to set a shared mailbox, with quite partial success. The INBOX is merged with the top level mailbox, and there are many more folders. To give an idea, for the shared account sharedacc(a)domain.org, this is how looks the folder structure: sharedacc |-folderA |-folderB \-folderC in the account for usera(a)domain.org, I see the following: usera |-folderD |-folderE |-folderF \-shared \-sharedacc So, I do not get to see folderA, folderB, folderC, etc. My configuration is: # 2.2.25 (7be1766): /etc/dovecot/dovecot.conf # Pigeonhole version 0.4.14 (099a97c) # OS: Linux 4.5.4-0 x86_64 Debian stretch/sid zfs mail_plugins = zlib expire acl plugin { acl = vfile acl_shared_dict = proxy::acl } dict { acl = mysql:/etc/dovecot/dovecot-dict-sql.conf.ext } namespace { list = children location = mdbox:/mnt/vmail/%%d/%%n:INDEXPVT=/mnt/vmail/indexes/shared/%%d/%%n prefix = shared/%%n/ separator = / subscriptions = yes type = shared } protocol lmtp { mail_plugins = zlib expire acl sieve } protocol imap { mail_plugins = zlib expire acl antispam imap_acl } the files I have one the account for sharedacc are: sharedacc |-dovecot-acl |-dovecot-acl-list \-mailboxes |-dovecot-acl |-folderA | \-dbox-Mails | \-dovecot-acl |-folderB | \-dbox-Mails | \-dovecot-acl \-folderC \-dbox-Mails \-dovecot-acl In dovecot-acl-list I have the following contents: 1474920778 folderA 1474920778 folderB 1474920778 folderC and in every dovecot-acl, I have: user=usera(a)domain.org akxeilprwts All the files on the filesystem are owned by the same vmail user. What is strange is that I can see all these folderA, folderB, folderC in roundcube, and I can click to subscribe to them. However, when I go back to the general view, the subscriptions have been reset and I see only sharedacc, without a thing inside. Finally, in kmail I can see the subscribed folders without a problem (??!) Can please somebody help me?

Setting hostdomain
by Arie Peterson 25 Sep '16

25 Sep '16

Hi all, Preparing for a replication setup, I read (at the bottom of <http://wiki2.dovecot.org/Replication>) that `dovecot --hostdomain` should give a different output on the two servers. This is not the case for me: both give "localhost". I'm trying to change my configuration to set the hostdomain to another value, but I can't find how to do this. I tried: • setting the environment variable DOVECOT_HOSTDOMAIN=mydomain in /etc/default/dovecot (which is read by the init script); • adding the line import_environment = TZ DOVECOT_HOSTDOMAIN=mydomain to dovecot.conf; • the combination of both of the above. However, after restarting dovecot none of these changes seem to have any effect: `dovecot --hostdomain` still returns "localhost". This is with dovecot version 2.2.13. How should one change this setting? Thanks, Arie

configure fail if libssl is named libssl-opt
by A. Schulze 25 Sep '16

25 Sep '16

Hello, I try to build dovecot with my own version of openssl. It's compiled in a way the libraries can coexist without symbol conflict with the real OpenSSL in /usr: They are named libssl-opt and libcrypto-opt. Now configure fail to find my libssl-opt: CFLAGS="..." CXXFLAGS="..." CPPFLAGS="..." LDFLAGS="..." SSL_LIBS='-lssl-opt -lcrypto-opt' ./configure ... --with-ssl=openssl ... checking for SSL_read in -lssl... no configure: error: Can't build with OpenSSL: libssl not found Is there an other way to tell configure the ssl libraries have other names?
