FTS delays
by Joan Moreau 21 Apr '19

21 Apr '19

Hi When I do a FTS search (using Xapian plugin) in the BODY part, the plugins returns the matching IDs within few milliseconds (as seen in the log). However, roundcube (connected on dovecot) takes ages to show (headers only vie IMAP) the few results (I tested with a matching requests of 9 emails) What could be the root cause ? Thank you

Extended logging / moved mails jumping back
by Martin Müller 20 Apr '19

20 Apr '19

Hi! About 4-6 MUA Thunderbird 60.6.1 are going to connect with dovecot 2.2.13/IMAP (debian 8) and are using the same user/password. This setup works for years flawless (updated clients and serversoftware). Since a few weeks there is one major trouble: I one of the client moves a mail from the inbox to a another IMAP-Folder, most of the moved mail are moved for the moment. But an unstable period later, the mails are moved back to the inbox. In rarely cases, the moved mail is copied (one in the inbox, one in the destinationfolder). Now I have to check, if this a Thunderbird-Issue or is this a dovecot-issue. For that reason, I will activate the extended logging of dovecot. ### ### ### ### dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf # OS: Linux 3.16.0-6-amd64 x86_64 Debian 8.11 auth_mechanisms = plain login debug_log_path = /var/log/mail.dovecot-debug disable_plaintext_auth = no info_log_path = /var/log/mail.dovecot-info listen = *,[::] log_path = /var/log/mail.dovecot-error log_timestamp = "%Y-%m-%d %H:%M:%S " mail_debug = yes mail_max_userip_connections = 100 mail_privileged_group = vmail passdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size quota = dict:user::file:/var/vmail/%d/%n/.quotausage sieve = /var/vmail/%d/%n/.sieve sieve_max_redirects = 25 } protocols = imap pop3 service auth { unix_listener /var/spool/postfix/private/auth { group = postfix mode = 0660 user = postfix } unix_listener auth-userdb { group = vmail mode = 0600 user = vmail } user = root } service imap-login { client_limit = 1000 process_limit = 512 } service lmtp { unix_listener /var/spool/postfix/private/dovecot-lmtp { group = postfix mode = 0600 user = postfix } } ssl_cert = </etc/postfix/smtpd.cert ssl_key = </etc/postfix/smtpd.key ssl_protocols = !SSLv3 userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-sql.conf driver = sql } protocol imap { mail_plugins = quota imap_quota } protocol pop3 { mail_plugins = quota pop3_uidl_format = %08Xu%08Xv } protocol lda { mail_plugins = sieve quota postmaster_address = postmaster(a)monarch.products4more.at } protocol lmtp { mail_plugins = quota sieve postmaster_address = postmaster(a)monarch.products4more.at } ### ### ### ### ### ### ### ### It works: dovecot logs to three differnt logfiles /var/log/mail.dovecot-* It doesnt work: plugin { mail_log_events = delete undelete expunge copy mailbox_delete mailbox_rename mail_log_fields = uid box msgid size } I cant see such events in the logfiles. Which switch is to turn on to log all events? Or do anyone know the reason for the annoying "copy/move-the-mail-back"-issue? Thank you in advance for all inputs. regards, martin

[Dovecot] Dovecot LDA/LMTP vs postfix virtual delivery agent and the x-original-to header

Does anyone know if the use of LMTP (or even the dovecot LDA) still loses the x-original-to header that the postfix vda adds and that I rely heavily on (since I use a lot of aliases), and if it does, is there any solution to get the original recipient added back in before final delivery? Everything I'm reading says that LMTP is better, but I really do need this header (or one like it) to be there so I know who the original recipient was (for filtering and other purposes).
