Proxy problem: "imap-login: Error: proxy(USERNAME): connect(10.x.x.178, 993) failed: Cannot assign requested address (after 0 secs, local=10.x.x.104)"
by Ralf Hildebrandt 21 Oct '14

After fixing the "duplicate compression" problem, we're now encountering "imap-login: Error: proxy(USERNAME): connect(10.x.x.178, 993) failed: Cannot assign requested address (after 0 secs, local=10.x.x.100)" in the logs. We already tried raising the ulimit, the max number of open files. Once we reach about 25k connections, we're getting the error above... for all local addresses. It seems as if the system cannot create any more outgoing connections. We already optimized: ---- snip ---- net.ipv4.tcp_fin_timeout=5 # down from 30s net.ipv4.tcp_tw_reuse=1 net.ipv4.tcp_tw_recycle=1 # http://redis4you.com/articles.php?id=012&name=Redis+high+traffic+connection… net.ipv4.ip_local_port_range=10000 65000 # http://www.fromdual.com/huge-amount-of-time-wait-connections net.ipv4.netfilter.ip_conntrack_max=524288 ---- snip ---- But still we get (once the load is rising beyond some point): # fgrep "Cannot assign requested address" /var/log/dovecot/dovecot.log |awk '{print $NF}' | sort | uniq -c | sort -n 142 local=10.x.x.100) 147 local=10.x.x.107) 148 local=10.x.x.106) 151 local=10.x.x.104) 151 local=10.x.x.109) 152 local=10.x.x.105) 156 local=10.x.x.110) 162 local=10.x.x.102) 165 local=10.x.x.101) 178 local=10.x.x.103) 189 local=10.x.x.108) We're using multiple local addresses when proxying to the backends -- [*] sys4 AG http://sys4.de, +49 (89) 30 90 46 64 Franziskanerstraße 15, 81669 München Sitz der Gesellschaft: München, Amtsgericht München: HRB 199263 Vorstand: Patrick Ben Koetter, Marc Schiffbauer Aufsichtsratsvorsitzender: Florian Kirstein

only inbox folder after courier-imap migration
by Luciano Gabriel Andino 21 Oct '14

21 Oct '14

Hello, after courier-dovecot-migrate.pl, the only folder appears in webmail menu is "Inbox". The others still are in Maildir "Maildir/.myfolder" and contains its "dovecot-uidlist" and "dovecot-keywords" files. May I need to edit some file? -- Saludos!!

Dovecot Auth Issue
by Austin Einter 21 Oct '14

21 Oct '14

Dear All I have been able to setup postfix and dovecot. Through command line, I can send mail out. Now I have installed roundcube in mail server side, and I am able to access like https://mydomain/webmail.com Login was failing. Then I debugged and modified settings in dovecot and using PAM for authentication. Now I trying to login to email server. I am not sure if authentication by dovecot and pam is successful. I enabled logging for dovecot. The below logs I get when a user "try" logs in. Oct 21 07:44:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Oct 21 07:44:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Oct 21 07:44:55 auth: Debug: auth client connected (pid=15357) Oct 21 07:44:55 auth: Debug: client in: AUTH 1 PLAIN service=imap secured lip=128.199.214.27 rip=128.199.214.27 lport=993 rport=43323 resp=AHRyeUBsb2FkbXVsdGlwbGllci5jb20AdHJ5MTIz Oct 21 07:44:55 auth-worker: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Oct 21 07:44:55 auth-worker: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Oct 21 07:44:55 auth-worker: Debug: pam(try,128.199.214.27): lookup service=dovecot Oct 21 07:44:55 auth-worker: Debug: pam(try,128.199.214.27): #1/1 style=1 msg=Password: Oct 21 07:44:55 auth: Debug: client out: OK 1 user=try Oct 21 07:44:55 auth: Debug: master in: REQUEST 1571291137 15357 1 b3cc155dfd3bb2fd576bfeeceaf1ce3d Oct 21 07:44:55 auth: Debug: passwd(try,128.199.214.27): lookup *Oct 21 07:44:55 auth: Debug: master out: USER 1571291137 try home=/var/mail/ mail=maildir:/var/mail/try system_groups_user=try uid=5001 gid=5001*Oct 21 07:44:55 imap-login: Info: Login: user=<try>, method=PLAIN, rip=128.199.214.27, lip=128.199.214.27, mpid=15361, TLS *Oct 21 07:44:55 imap(try): Info: Disconnected: Logged out bytes=29/399* >From the logs above (in bold), I hope auth is successful, then in last line why it is logging out.., I am confused , not sure if auth is completely successful or not.

SMTP authentication setup
by Brian 21 Oct '14

21 Oct '14

At my company we've had a longstanding problem of not being able to send email from devices outside of our internal network and any specific IP address that we open the relay to. As it turns out, SASL has never been set up. I need to set up SASL ASAP but none of the guides I've found seem to work. This is the latest guide I tried: http://wiki2.dovecot.org/HowTo/PostfixAndDovecotSASL I did everything on here minus the last part because it's on the same server. Also, instead of submission inet n - - - - smtpd I did: 127.0.0.1:1025 inet n - - - - smtpd After all is done, however, I'm unable to send any mail. Thunderbird just says sending message but doesn't send and I don't even get an error. I end up having to disable SASL again before I can send mail. Dovecot version 2.0.9 Postfix version 2.6.6 CentOS 6 I have Postfix, Dovecot, and ASSP on the same server. Thanks everyone. -- This email was Virus checked by Astaro Security Gateway. http://www.sophos.com

90-sieve.conf syntax - moving from v2.0.x to v2.2.x
by deoren 21 Oct '14

21 Oct '14

Hi, I'm currently running version v2.0.x in production (using Maildir storage) and it's been working well. I'm interested in moving to version 2.2.x and am preparing a test server to do so. As I have been merging the conf file changes between the two versions I noticed syntax changes for the 90-sieve.conf file. There are now 'locations' and presumably to keep referring to local content I'll need to use the 'file:' location type. On my production box (v2.0.x) I have 90-sieve.conf configured like so: sieve = /var/vmail/sieve/%d/%n/.dovecot.sieve sieve_default = /var/vmail/sieve/global.sieve sieve_dir = /var/vmail/sieve/%d/%n/sieve_dir Inside of the /var/vmail/sieve/%d/%n/ directory (i.e., /var/vmail/sieve/example.com/testuser/) I find: drwxr-xr-x 3 vmail vmail 64 Oct 19 12:07 . drwxr-xr-x 9 vmail vmail 101 Jun 21 10:47 .. lrwxrwxrwx 1 vmail vmail 25 Jun 21 11:10 .dovecot.sieve -> sieve_dir/roundcube.sieve -rw------- 1 vmail vmail 3694 Oct 19 12:07 .dovecot.svbin drwx------ 3 vmail vmail 38 Oct 19 11:58 sieve_dir and that works well. I look at the current wiki documentation: http://wiki2.dovecot.org/Pigeonhole/Sieve/Configuration and I find that the 'seive_dir' conf option is still listed, but the comments for it appear very similar to the comments that precede the 'sieve' conf option in the stock 90-sieve.conf file: # The location of the user's main Sieve script or script storage. The LDA # Sieve plugin uses this to find the active script for Sieve filtering at # delivery. The "include" extension uses this location for retrieving # :personal" scripts. This is also where the ManageSieve service will store # the user's scripts, if supported. Assuming that the 'sieve' and 'sieve_dir' conf settings have not been merged into just 'sieve' (and that I need to use the 'file:' location specifier), is this how I would configure the two settings for Dovecot 2.2.x? sieve = file:/var/vmail/sieve/%d/%n;active=~/.dovecot.sieve sieve_dir = file:/var/vmail/sieve/%d/%n/sieve_dir If the two have been merged, how would I go about configuring the 90-sieve.conf file to get the same results? Thanks for your help.

replication sieve settings
by Martin Schmidt 20 Oct '14

20 Oct '14

Hello, can someone give me a hint, where to find an info, how to setup dovecote replication with sieve? On my active.active setup, it replicates the user mdboxes and sieve works also, on the active destination fileserver. Client changes the sieve, tests work fine. But the sieve file won't get replicated to the replica server. As i've researched, it was introduced in dovecot v2.2.rc3 Is it default, that doveadm replicator replicate '*' includes the sieve and i made a config error? Or is there an option to set for the replication service? On dovecot director server, i've set director in conf.d/20-managesieve.conf service managesieve-login { executable = managesieve-login director inet_listener sieve { port = 4190 } } and added sieve to plugins in conf.d/20-lmtp.conf protocol lmtp { mail_plugins = $mail_plugins sieve } doveconf -n ... director_mail_servers = 192.168.200.10 192.168.200.11 director_servers = 192.168.200.1:9090 192.168.200.2:9090 disable_plaintext_auth = no doveadm_port = 24245 lmtp_proxy = yes 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 plugin { sieve = file:~/sieve;active=~/.dovecot.sieve } protocols = " imap lmtp sieve pop3" ... service managesieve-login { executable = managesieve-login director inet_listener sieve { port = 4190 } } ... protocol lmtp { auth_socket_path = director-userdb mail_plugins = " sieve" } ...

fixes for quota support on NetBSD
by Thomas Klausner 20 Oct '14

20 Oct '14

Hi! dovecot-2.2.13 already has quota support for NetBSD, but it's buggy. The attached patches by Manuel Bouyer <bouyer(a)NetBSD.org> fix the issues. There is one thing that's not nice in them: one include is now for "/usr/include/quota.h" since dovecot comes with its own file "quota.h" which is earlier in the search path. Perhaps dovecot's copy can be renamed to dovecot-quota.h or to some other non-conflicting name? Cheers, Thomas

last_login plugin with MySQL
by Luigi Rosa 20 Oct '14

20 Oct '14

Hi, I have a Dovecot test installation with MySQL userbase and authentication where I am trying to setup last_login plugin with SQL dictionary I read http://wiki2.dovecot.org/Plugins/LastLogin and I addes this to my configuration plugin { last_login_dict = sql:/etc/dovecot/dovecot-sql.conf.ext } mail_plugins = $mail_plugins stats protocol imap { mail_plugins = $mail_plugins imap_stats last_login } When I log in with IMAP I get this error: Error: last_login_dict: dict_init(sql:/etc/dovecot/dovecot-sql.conf.ext) failed: Unknown dict module: sql /etc/dovecot/dovecot-sql.conf.ext is the file taht contains the SQL configuration. If I put mysql instead of sql the result is the same: Error: last_login_dict: dict_init(mysql:/etc/dovecot/dovecot-sql.conf.ext) failed: Unknown dict module: mysql The output of doveconf -n follows. Do you have any idea on how to use MySQL for last_login?
