[Dovecot] it's possible to send email from the system after the mailbox quota is full
by ihab 13 Jan '14

13 Jan '14

it's possible to send email from the system after the mailbox quota is full i don't want warning mail i want something else because when i use warning on 100% or 99% or less some times the last message be too large (so if just 5% is free from quota size and the last msg size is 6% from quota ) after that the mailbox will not receive this message or warning message . -- View this message in context: http://dovecot.2317879.n4.nabble.com/it-s-possible-to-send-email-from-the-s… Sent from the Dovecot mailing list archive at Nabble.com.

[Dovecot] dsync error: gz trailer has wrong CRC value
by Joe Beaubien 13 Jan '14

13 Jan '14

A few days ago by dovecot installation started behaving weirdly. First it was doveadm fts optimize which would fail (a thread running about that) and now it's dsync, which means my backups are not working. This all started a few days ago, which I find a little weird, because I haven't messed around with the dovecot setup in months. I've been searching the internet, but didn't find anything useful yet. Would anyone know how to fix the errors in the log below? Thanks, -Joe dovecot version is 2.1.7 Here is the log: dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): gz trailer has wrong CRC value at 16966298 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Error: read(msg input) failed: Invalid argument dsync(archive): Error: zlib.read(/mba_data/emails/archive/storage/m.1885): missing gz header at 16973513 dsync(archive): Panic: file mail-index-transaction-update.c: line 906 (mail_index_update_ext): assertion failed: (seq > 0 && (seq <= mail_index_view_get_messages_count(t->view) || seq <= t->last_new_seq)) dsync(archive): Error: Raw backtrace: /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(+0x4203a) [0x7f3a5150503a] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(default_fatal_handler+0x2a) [0x7f3a515050fa] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot.so.0(i_fatal+0) [0x7f3a514dc3f0] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_index_update_ext+0x1c7) [0x7f3a51804927] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa8746) [0x7f3a517f7746] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_cache_transaction_commit+0x4c) [0x7f3a517f7a2c] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa8af3) [0x7f3a517f7af3] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(+0xa2cea) [0x7f3a517f1cea] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mail_index_transaction_commit_full+0x84) [0x7f3a51800754] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(index_transaction_commit+0x8a) [0x7f3a517f209a] -> /opt/dovec ot/lib/d ovecot/lib20_zlib_plugin.so(+0x3b7a) [0x7f3a4fe8cb7a] -> /opt/dovecot/lib/dovecot/lib20_fts_plugin.so(+0xb481) [0x7f3a5009b481] -> /opt/dovecot-2.1.7/lib/dovecot/libdovecot-storage.so.0(mailbox_transaction_commit_get_changes+0x3d) [0x7f3a517c9c4d] -> /opt/dovecot/bin/dsync() [0x4297e6] -> /opt/dovecot/bin/dsync() [0x42b222] -> /opt/dovecot/bin/dsync(dsync_worker_select_mailbox+0x2e) [0x4291be] -> /opt/dovecot/bin/dsync() [0x424c75] -> /opt/dovecot/bin/dsync() [0x424db7] -> /opt/dovecot/bin/dsync(dsync_brain_msg_sync_more+0x22c) [0x4245ec] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x459) [0x422fc9] -> /opt/dovecot/bin/dsync() [0x423e61] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x7f1) [0x423361] -> /opt/dovecot/bin/dsync() [0x423cdc] -> /opt/dovecot/bin/dsync(dsync_brain_sync+0x832) [0x4233a2] -> /opt/dovecot/bin/dsync(dsync_brain_sync_all+0x18) [0x423ee8] -> /opt/dovecot/bin/dsync() [0x420f36] -> /opt/dovecot/bin/dsync() [0x4215b2] -> /opt/dovecot/bin/dsync() [0x40e798]

[Dovecot] Dovecot quota with MySQL - username issue
by michael 11 Jan '14

11 Jan '14

Hi all, I'm using Dovecot 2.2.8 with quota using a MySQL backend. The Quota plugin is listed for POP3, IMAP and LDA. When it is enabled for LDA, it populates the "username" field in the MySQL table with e mail addresses. I end up with a mixture of email addresses and usernames, which causes things to not fully work. It *should* be just usernames. the LDA SQL statement is: user_query = \ SELECT mailboxes.username, accounts.uid, accounts.uid AS gid, \ concat('/home/',mailboxes.username) AS home, \ (SELECT IF(accounts.new_mail_fmt=1, \ CONCAT('Maildir:',home,'/Maildir'), \ CONCAT('mbox:',home,'/Maildir:INBOX=/var/spool/mail/',mailboxes.username))) AS mail_location \ FROM mailboxes JOIN accounts ON accounts.username=mailboxes.username \ WHERE (mailboxes.email='%u' || \ (mailboxes.email=CONCAT('@','%d') AND (SELECT COUNT(email) FROM mailboxes \ WHERE email='%u') = 0) AND mailboxes.active IS TRUE) It clearly knows the username. Usernames on this system are just names, not full email addresses. The configuration of Quota Dict is: dovecot.conf dict/quotadict = mysql:/etc/dovecot/dovecot-dict-sql.conf ... quota = dict:user::proxy::quotadict dovecot-dict-sql.conf map { pattern = priv/quota/storage table = quota username_field = username value_field = bytes } map { pattern = priv/quota/messages table = quota username_field = username value_field = messages } Can this be fixed?

[Dovecot] Possible to force cipher order?
by Matthias Rieber 10 Jan '14

10 Jan '14

Hi, is it possible to force the server cipher order instead of the clients preferences? When I connect with openssl using these ciphers: 'RC4-SHA:DHE-RSA-AES256-GCM-SHA384' -> RC4-SHA will be selected and with 'DHE-RSA-AES256-GCM-SHA384:RC4-SHA' -> DHE-RSA-AES256-GCM-SHA384 It seems to be recommended for webservers to override that due to bad clients choices and increasing knowledge, like RC4 vs. BEAST, AES128 better (theoretical) than AES256. Regards, Matthias

[Dovecot] Message filtering capability at IMAP proxy
by CM Reddy 10 Jan '14

10 Jan '14

Hi, I would like process the messages at Dovecot IMAP proxy. In one of the documents, it was mentioned that Dovecot proxy currently supports on the fly message filtering in latest releases. Will it it possible to extend the filtering feature to handle the following requirements. 1. Parse the email at IMAP proxy. 2. Replace the links with some other secure links. 3. Replace the attachments with some other document. It would be great, if any one can provide some pointers to move forward. - Thanks in advance CM Reddy
