[Dovecot] Dovecot 2.1.13: some questions about the mail-filter plugin
by Axel Luttgens 02 Jun '14

02 Jun '14

Looking at mail_filter_mailbox_allocated() of src/plugins/mail-filter/mail-filter-plugin.c: if ((class_flags & MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS) == 0 && (class_flags & MAIL_STORAGE_CLASS_FLAG_BINARY_DATA) != 0 && muser->out_socket_path != NULL) v->save_begin = mail_filter_mail_save_begin; it seems that a backend with MAIL_STORAGE_CLASS_FLAG_OPEN_STREAMS unset and MAIL_STORAGE_CLASS_FLAG_BINARY_DATA set is expected by the plugin. Technically, … [View More]

[Dovecot] "doveadm fetch" fetches mails twice?
by Peer Heinlein 01 Jun '14

01 Jun '14

-----BEGIN PGP SIGNED MESSAGE----- Hash: SHA1 As far as I understood fetch -u p.heinlein(a)jpberlin.de hdr mailbox-guid [...]93d5 uid 58175 should fetch exactly the header of the specified mail. But on my Dovecot 2.2.12 it fetches the header *twice* (same with body, same with text). ======================================== hdr: Return-Path: <hello(a)example.com> Delivered-To: <p.heinlein(a)jpberlin.de> [...] hdr: Return-Path: <hello(a)example.com> Delivered-To: <p.… [View More]

[Dovecot] Combining userdbs
by Bubreg István 01 Jun '14

01 Jun '14

Hi, I think that using more than one userdb with setting the result actions doesn't work as expected from the documentation. The goal would be to set user-specific quotas for a few users with a specific passwd-file like this : cat /etc/dovecot/quotas foo:x::::::userdb_quota_rule=*:storage=2G The first userdb is passwd (with pam passwd): userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok skip = never } The second one … [View More]is for the specific quota userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } User 'foo' exists in (pam) passd, but there's no place to store his own quota rule, that's why came handy to use a second userdb for storing just one extra field. That's working quiet well, he default quota is overriding form passwd-file. BUT: I've played a lot with changing the result_* and the 'skip' parameters, but none of them worked in the situation where a user ('bar') _only_ exists in passwd (and has to use the default quota config). doveadm quota get -u bar says doveadm(bar): Fatal: User doesn't exist With changing the parameters this error has gone, but the second userdb doesn't used for user 'foo' - even if the parameters are : userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue <-- in theory, the next userdb is coming skip = never } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue result_internalfail = continue result_success = return-ok skip = notfound } My question is that how should i set the result_* and 'skip' parameters to solve this : - there's a default quota rule in the config - some (a few) users has a larger quota - there's no way to store the user-specific quotas in the 'real' userdb (because it's pam/passwd) Thank you for your effort. # dovecot -n # 2.2.13 (de9b10f2e168): /etc/dovecot/dovecot.conf # OS: Linux 3.11.0-15-generic i686 Ubuntu 12.04.4 LTS auth_debug = yes auth_debug_passwords = yes auth_verbose = yes auth_verbose_passwords = yes disable_plaintext_auth = no listen = * log_path = /var/log/dovecot.log mail_debug = yes mail_location = maildir:~/Maildir mail_plugins = " quota" managesieve_notify_capability = mailto managesieve_sieve_capability = fileinto reject envelope encoded-character vacation subaddress comparator-i;ascii-numeric relational regex imap4flags copy include variables body enotify environment mailbox date ihave duplicate 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 } plugin { quota = maildir:User quota quota_rule = *:storage=1G quota_rule2 = Trash:storage=+100M sieve = ~/.dovecot.sieve sieve_dir = ~/sieve } protocols = " imap sieve" service managesieve-login { inet_listener sieve { port = 4190 } } service managesieve { process_limit = 1024 } ssl = no ssl_cert = </etc/dovecot/private/dovecot.pem ssl_key = </etc/dovecot/private/dovecot.pem userdb { driver = passwd result_failure = return-fail result_internalfail = return-fail result_success = continue-ok } userdb { args = username_format=%n /etc/dovecot/quotas driver = passwd-file result_failure = continue-ok result_internalfail = continue-ok skip = notfound } protocol imap { mail_plugins = quota } [View Less]

[Dovecot] Disabling plus sign extension delimiter in lmtp listener (or userdb)
by Benoit Panizzon 01 Jun '14

01 Jun '14

Hello We have migrated our email services from a server, which did not support IMAP and folders, therefore threated the plus sign + as a normal character in a part of an email address. Our new server delivers the emails via lmtp to dovecot. the few users which got a + character in the username first could not log-in (fixed by adding + to auth_username_chars). Now the next problem turn out to be, that the lmtp listener stripps everything after the + sign. The MTA correctly sends the … [View More]
