Sieve vacation address problem
by Harald Leithner 27 Jul '16

27 Jul '16

Hi, it seams I have a problem with the vacation script. The problem is that the vacation answers to a address that is not listed in the sieve script. I checked the postfix master.conf which delivers to lda correct parameter. In the logfile you can see that that office(a)example.com received a message that get delivered to user(a)example.com (with the sievescipt) and to office(a)example.com (another user without script). The sieve script has the :addresses parameter only set to user(a)example.com Is something wrong with my setup? We use roundcube + sievemanage to create sieve scripts. Sievescript: ## Generated by Roundcube Webmail SieveRules Plugin ## require ["date","relational","vacation"]; # rule:[Urlaub] if allof (currentdate :zone "+0200" :value "gt" "date" "2016-07-22", currentdate :zone "+0200" :value "lt" "date" "2016-08-08") { vacation :days 1 :addresses ["user(a)example.com"] :subject "Abwesenheitsnotiz" text: Thx i'm not here . ; } -------------- postfix

Opportunistic quota recalc
by Tom Sommer 27 Jul '16

27 Jul '16

I'm switching quota backend to redis (from maildir++), so all my current usages are reset. I get that I can do "doveadm quota recalc -A", but it takes forever (and auth processes time out/crash). It would make much more sense to recalc the usage on login if the current usage is unset. Is there no way to do a recalc-quota-on-first-login? Thanks. -- Tom Sommer

Converting mailboxes to UTF-8
by Артем Перекресний 27 Jul '16

27 Jul '16

Is any proven routine to migrate mailboxes from mUTF-7 to UTF-8 encoding? I've try to use doveadm list/mutf7/rename but have been stuck with nested inboxes. Say I have the next structure: INBOX INBOX.жыр INBOX.жыр.ядъ encoded for FS respectively as .INBOX .INBOX.&BDYESwRA- .INBOX.&BDYESwRA-.&BE8ENARK- When I've try to rename INBOX.жыр with doveadm mailbox rename -u me -s "INBOX.&BDYESwRA-" $(doveadm mailbox mutf7 -7 "INBOX.&BDYESwRA-") I've get the next: .INBOX .INBOX.жыр .INBOX.жыр.&BE8ENARK- Sure when I've try to rename .INBOX.жыр.&BE8ENARK- I've get a message that this is not a valid mUTF7-encoded string. So that is the question.

imap & pop3 using same mailbox with virtual plugin
by Michael Fox 26 Jul '16

26 Jul '16

This is a noobie question, so bear with me if it's not worded correctly: Primary Requirements: 1) I'd like to have two namespaces - one private/per-user, and one public (visible by all logged-in users). The public mailbox would be used to distribute information to all users. 2) I'd like both POP3 and IMAP users to see both namespaces. As I understand it, this requires the use of the virtual plugin to create a virtual namespace which would mix together the private and public namespaces into one mailbox. I have read: http://wiki.dovecot.org/Plugins/Virtual https://sys4.de/de/blog/2013/02/11/dovecot-virtual-setup-mit-globaler-sieve- spamfilter-regel-fur-pop3-nutzer/ (via Google translation) I don't really understand the example MySQL code (too much "..." for me to follow) in the above web pages. As I understand it (and I could be very wrong), the solution relies on a MySQL query to determine which namespace should have inbox = yes -- the private namespace or the virtual namespace -- depending on if the user is an imap or pop3 user, respectively. Question 1: How would this be done on a user-by-user basis if the userdb is a passwd-file flat file? Would it be something like this? -- Userdb extra fields for IMAP User: userdb_namespace/inbox/inbox=yes -- Userdb extra fields for POP3 User: userdb_namespace/virtual/inbox=yes Question 2: If I want to allow any user to use either POP3 or IMAP, then could I do it this way? protocol imap { namespace inbox { inbox = yes } } protocol pop3 { namespace virtual { inbox = yes } } Thanks, Michael

Dovecot cannot find mailboxes
by C. Andrews Lavarre 26 Jul '16

26 Jul '16

Edgar, thank you for your help: I have solved gaining access from a client (Evolution) via IMAP to the server: I can refresh, add folders, and delete folders. But I am still confounded, as IMAP does not see any mailboxes. Neither we from the command line (telnet, openssl, login, select) nor the system can find the mailbox, despite following FindMailLocation: telnet, openssl, login, then b select inbox * 0 EXISTS * 0 RECENT and postfix fails with 2016-07-23T21:22:37.312039-04:00 lavarre postfix/error[17088]: A8DA2C1BB2: to=<andy(a)privustech.com>, orig_to=<andy>, relay But the mailboxes do exist in /var/mail/vhosts/privustech.com/andy and we point to them in /etc/dovecot/users. doveconf -n is attached. ----- Two issues are: 1. file permissions and ownership 2. virtual versus system users 1. It appears that having the correct ownership and permissions on various files is critical (of course), but those parameters must also be included in the interior of the /etc/dovecot/user. So if you change permissions you also must change that file. For example, you said: i also noticed your certificate chain is broken. http://wiki2.dovecot.org/testinstallation I worked through this link, thank you. Changing permissions for the directories /var/mail/* to root:mail ($UID:$GID = 1000:12) and then changing /etc/dovecot/users correspondingly to user(a)privustech.com :{plain}actualpassword: 1000:12 ::/var/mail/vhosts/privustech.com/user now allows a normal login. and we can create a new folder (e.g., work) and delete it. However, this is at variance with http://wiki2.dovecot.org/HowTo/SimpleVirtualInstall which says to set the ownership to vmail:vmail ($UID:$GID = 100: 5000). Doing so breaks dovecot. 2. The various links suggest that having virtual users is preferable to setting system users. The former do not require directories under /homebut they do require a directory in the mail system, which I have provided under /var/mail/vhosts. It also turns out that for virtual users you must include the domain (andy(a)privustech.com) Making that change allowed the success reported above. But despite that, we still cannot find the mailboxes on login. Any thoughts on how to have IMAP find the mailboxes (beyond FindMailLocation, which doesn't seem to work for me) would be most appreciated. Kind regards, Andy

Hi, hope someone can help also if this problem is difficult to debug I have a mail account that has on file system 32GB however quotacalculation gives a higher value 41262146 I've already tried to: - doveadm quota recalc -u user@domain - removing maildirsize from /users/vmail/domain/user/Maildir - checking all emails messages if they have the size in the name (S=xxxx) different from the real size. I used the script here in attach giving it in input the output of << find /users/vmail/domain/user -name *S=* -type f>> I don't have mail compression the mail account have a lot of mailboxes and at now 78319 messages doveadm quota get -u user@domain Quota name Type Value Limit % User quota STORAGE 41262146 42991616 95 User quota MESSAGE 78319 - 0 this is the same command run with -Dv doveadm(root): Debug: Loading modules from directory: /usr/lib64/dovecot doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/lib10_quota_plugin.so doveadm(root): Debug: Loading modules from directory: /usr/lib64/dovecot/doveadm doveadm(root): Debug: Skipping module doveadm_acl_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib10_doveadm_acl_plugin.so: undefined symbol: acl_user_module (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_expire_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib10_doveadm_expire_plugin.so: undefined symbol: expire_set_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/doveadm/lib10_doveadm_quota_plugin.so doveadm(root): Debug: Module loaded: /usr/lib64/dovecot/doveadm/lib10_doveadm_sieve_plugin.so doveadm(root): Debug: Skipping module doveadm_fts_lucene_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib20_doveadm_fts_lucene_plugin.so: undefined symbol: lucene_index_iter_deinit (this is usually intentional, so just ignore this message) doveadm(root): Debug: Skipping module doveadm_fts_plugin, because dlopen() failed: /usr/lib64/dovecot/doveadm/lib20_doveadm_fts_plugin.so: undefined symbol: fts_backend_rescan (this is usually intentional, so just ignore this message) doveadm(user@domain): Debug: Added userdb setting: mail_location=maildir:/users/vmail/domain/user/Maildir doveadm(user@domain): Debug: Added userdb setting: plugin/quota_rule=*:storage=41G doveadm(user@domain): Debug: Effective uid=5000, gid=5000, home=/users/vmail/domain/user doveadm(user@domain): Debug: Quota root: name=User quota backend=maildir args= doveadm(user@domain): Debug: Quota rule: root=User quota mailbox=* bytes=44023414784 messages=0 doveadm(user@domain): Debug: Quota warning: bytes=41822244044 (95%) messages=0 reverse=no command=quota-warning 95 user@domain doveadm(user@domain): Debug: Quota grace: root=User quota bytes=20971520 doveadm(user@domain): Debug: Namespace inbox: type=private, prefix=, sep=, inbox=yes, hidden=no, list=yes, subscriptions=yes location=maildir:/users/vmail/domain/user/Maildir doveadm(user@domain): Debug: maildir++: root=/users/vmail/domain/user/Maildir, index=, indexpvt=, control=, inbox=/users/vmail/domain/user/Maildir, alt= Quota name Type Value Limit % User quota STORAGE 41202926 42991616 95 User quota MESSAGE 78247 - hope someone can help I'm running dovecot-2.2.10-5.el7 on centos7

postconf -n display error for "remote"?
by Michael Fox 25 Jul '16

Is this a bug? I configured the following: remote 192.168.7.128/27 { ssl = no } remote 192.168.7.0/24 { ssl = yes } But, when I run doveconf -n, I see: remote 192.168.7.0/24/24 { ssl = yes } remote 192.168.7.128/27/27 { ssl = no } Note the repeated network prefix length (/27/27 and /24/24). Is there a way to tell for sure whether this is just a cosmetic issue or something that could cause a problem? Michael
