[Dovecot] ECDSA certificate support
by SIW 11 May '14

11 May '14

Does the latest version of Dovecot support ECDSA certificates? I had a look in: http://wiki2.dovecot.org/SSL but it didn't answer my question. Can someone please help or point me in the right direction? I'd also like to know if I can run an RSA cert AND an ECDSA certificate at the same time in Dovecot (like you can in Postfix). Many thanks.

[Dovecot] dovecot 2.2.9 - ssl_cert and ssl_key ignored
by Alexandru Bostina 11 May '14

11 May '14

Hello, It seems that Dovecot ignores the new /ssl_cert and ssl_key /settings. Using them in the dovecot configuration results in the error: Fatal: Couldn't parse private ssl_key: error:0906D06C:PEM routines:PEM_read_bio:no start line: Expecting: ANY PRIVATE KEY] Using the old /ssl_//cert//_file/ and /ssl_key_file/ results in their being obsolete warning but no fatal error.

[Dovecot] Only part of sieve script works
by Sebastian Schlingmann 10 May '14

10 May '14

Hi, I am using Dovecot 2.2.11 with Pigeonhole on Arch Linux. I have a partly working sieve script (pasted to the end of this mail) which sorts mail into various imap folders. The first, third and fourth if blocks work just fine. The second and fifth block do not sort any mails. However, if I apply the script with sieve-test to mails the second and fifth block seem to work. How is the manual check with sieve-test different from the sieve filtering during mail delivery? I am thankful for any hints. Sebastian this is the sieve script I am talking about require "fileinto"; # Musik wegsortieren if anyof ( header :comparator "i;ascii-casemap" :contains "Subject" "Mixing.DJ", header :comparator "i;ascii-casemap" :contains "Subject" "John B", header :comparator "i;ascii-casemap" :contains "Subject" "FLOSS Weekly", header :comparator "i;ascii-casemap" :contains "Subject" "BrainStuff", header :comparator "i;ascii-casemap" :contains "Subject" "Nerdy Show", header :comparator "i;ascii-casemap" :contains "Subject" ["My Brother", " My Brother And Me"], header :comparator "i;ascii-casemap" :contains "Subject" "MoJoMenace", header :comparator "i;ascii-casemap" :contains "Subject" "GWJ Conference Call", header :comparator "i;ascii-casemap" :contains "Subject" "Welcome to Night Vale", header :comparator "i;ascii-casemap" :contains "Subject" "International Waters" ) { fileinto "Feeds.music"; stop; } # Youtube wegsortieren if address :all :comparator "i;ascii-casemap" :contains "From" "noreply(a)youtube.com" { fileinto "Feeds.Youtube"; stop; } # Awesomer wegsortieren if header :comparator "i;octet" :contains "Subject" "[The Awesomer]" { fileinto "Feeds.Awesomer"; stop; } # Feeds sortieren if address :all :comparator "i;octet" :contains "From" "sebi+feedmailer(a)mighty.selfhost.bz" { fileinto "Feeds"; stop; } # AIStA wegsortieren if header :comparator "i;ascii-casemap" :contains "Received" "webmail.awista.net" { fileinto "AIStA"; stop; }

[Dovecot] Denial of Service attacks against Dovecot v1.1+
by Timo Sirainen 09 May '14

09 May '14

There's an upper limit to how many IMAP/POP3 connections can exist that haven't logged in (and separate limits for post-login). Normally when this limit is reached, the oldest connection gets disconnected. There is of course some potential to try to DoS Dovecot by doing a lot of IMAP/POP3 connections, but because the oldest connection always gets destroyed this requires quite a lot of activity from the attacker. This "destroy oldest connection" however hasn't been working in v1.1+ releases for connections that have started SSL/TLS handshake, but haven't finished it. So an attacker could just do a bunch of TCP connections to port 993 and leave them hanging around and Dovecot would pretty quickly reach the upper limit without being able to disconnect any of the oldest connections. Here are patches to fix this: http://hg.dovecot.org/dovecot-2.2/rev/41622541a7a3 http://hg.dovecot.org/dovecot-2.1/rev/b7ac23b4d339 http://hg.dovecot.org/dovecot-2.0/rev/48f90e7e92dc http://hg.dovecot.org/dovecot-1.2/rev/8ba4253adc9b http://hg.dovecot.org/dovecot-1.1/rev/fe0e6550585c The fix will be in v2.2.13. Maybe also in v2.1.18 if I decide to release it. For older releases you need to patch it yourself. For people who are using dovecot-ee releases the fix is also in v2.2.12.12 and v2.1.7.7 releases.

[Dovecot] Strange behavior on with "listescape" and "lda_mailbox_autocreate" - double entries
by Patrick De Zordo 09 May '14

09 May '14

Hello Guys, we are using Dovecot since years; all working flawless but one strange behavior: Let me explain.. - we have enabled the "listescape" plugin in "15-lda.conf", "10-mail.conf" and "20-imap.conf". - we use the following default namespace in "10-mail.conf": --------------- 10-mail.conf ----------------------------------------- namespace { type = private prefix = separator = / inbox = yes subscriptions = yes } ---------------------------------------------------------------------------------------- - we use a sieve script that automatically generates folders in the following form (example): ---------------------------------------------------------------------------------------- ".INBOX.2014.05.patrick.incoming" for user "patrick(a)xx.com" ".INBOX.2014.05.patrick.outgoing" for user "patrick(a)xx.com" ".INBOX.2014.05.p\2edezordo.incoming" for user "p.dezordo(a)xx.com" ---------------------------------------------------------------------------------------- This is ok, but the automatically generated "subscriptions"-file of the user contains double lines (the second line is something strange?!); the second one should not be created, its totally wrong..! --------------- subscriptions ----------------------------------------- Trash Sent INBOX.2014.05.patrick.incoming INBOX.2014.05.patrick.outgoing INBOX.2014.05.p\2edezordo.incoming INBOX\2e2014\2e05\2ep\5c2edezordo\2eincoming <----- this line!?!?!? ---------------------------------------------------------------------------------------- Have you any ideas whats going on? Could this be a bug, or misconfiguration? Thanks in advance!! Greeting from Italy! Patrick.

[Dovecot] Disable IMAP for ONE user only
by SIW 09 May '14

09 May '14

I use MySQL to store my virtual users passwords and I am running the latest version of Dovecot. What I need to do is have one particular user have ONLY access to their email via Roundcube (webmail) and no IMAP/SMTP access. Therefore, how do I disable IMAP/SMTP access for just one user?

[Dovecot] imapc with Outlook.com transfers max 22-23 messages per mailbox!?
by Nicholas Riley 08 May '14

08 May '14

Hi, I'm trying to migrate a user from Outlook.com IMAP to Dovecot. I'm using a setup similar to that on http://wiki2.dovecot.org/Migration/Dsync: imapc_host = imap-mail.outlook.com imapc_user = [...](a)hotmail.com imapc_password = [...] imapc_features = rfc822.size fetch-headers mail_prefetch_count = 20 imapc_port = 993 imapc_ssl = imaps imapc_ssl_verify = yes ssl_client_ca_dir = /etc/ssl # this needs fixing on the wiki page Here's how I sync a single mailbox, which should have a few hundred messages in it: % doveadm -D -v -c [...] sync -1 -R -u [...] -m Avalon imapc: Output is at http://sabi.net/temp/sync.txt But every mailbox contains at most 22-23 messages. % for i in Maildir/**/cur; do echo $i $(ls -1 $i | wc -l) done Maildir/Alaska/cur 23 Maildir/Avalon/cur 22 Maildir/Christine Scott/cur 22 Maildir/Cornell/cur 22 Maildir/Coupons/cur 10 Maildir/Deleted/cur 22 [...] I was using 2.2.9 but I also tried with the dovecot-2.2 hg tip and did not see any difference. Is there a rawlog equivalent for imapc? I'm hoping that there is a simple protocol usage change that could let me get entire mailboxes. -- Nicholas Riley <njriley(a)illinois.edu>
