[Dovecot] 76Gb to 146Gb [Resolved]
by Spyros Tsiolis 23 Oct '12

23 Oct '12

Hello all, I would like to thank you all for your kind replies and feedback in regards to migrating from a smaller hdd to a bigger one (namely from 72gb to 146gb). I finally found a painless way of doing this. Since I believe that this is still an off-topic post, if anyone is interested in the solution i've adopted for this, let me know by replying to me privately. If, however, you don't mind me posting here, let me know. Many many thanks go to Alexander Hoogerhuis, the "mad Norwegian" :-) who helped me on this too much to describe here. Alex, you are a true sport. Thank you again people. All the Best, spyros ---- "I merely function as a channel that filters music through the chaos of noise" - Vangelis

[Dovecot] (new) director issues in 2.1.10
by Kelsey Cummings 23 Oct '12

23 Oct '12

Timo - I upgraded to 2.1.10 on our director servers two nights ago and apart from errors associated with the directors processes restarting everything looked great for ~24 hours until I failed our the real servers last night to update the nfs mount options for the spools. I followed the suggested procedure for each backend server, just run on one of the directors, which seemed to work as expected. doveadm director add x.x.x.x 0 doveadm director flush x.x.x.x The following errors on the directors that started after this went unnoticed until this AM. director: User bb host lookup failed: Timeout - queued for 30 secs (Ring synced for 36 secs) director: User cc host lookup failed: Timeout - queued for 48 secs (Ring synced for 66 secs, user refreshed 12 secs ago) director: User dd host lookup failed: Timeout - queued for 124 secs (Ring synced for 119 secs, weak user, user refreshed 155 secs ago) director: User ee host lookup failed: Timeout - queued for 79 secs (Ring synced for 119 secs, weak user, user refreshed 113 secs ago) ... User ff host lookup failed: Timeout - queued for 30 secs (Ring synced for 7427 secs, weak user, user refreshed 620 secs ago) This continued, combined with occasional login timeouts (as reported by some internal imap clients.) The login delays/timeouts got bad enough that our load balancers dropped both the servers while I was investigating. They seem to be okay after being restarted. -K

[Dovecot] auth timeout state=2, bad?
by Bernhard Schmidt 22 Oct '12

22 Oct '12

Hello, we run Dovecot 2.1.7 as SASL backend for our Postfix SMTP-AUTH farm and see this error message occasionally Oct 22 16:15:32 lxmhs52 dovecot: auth: PLAIN(?,xx.xx.xx.xx): Request 0.21 timeouted after 150 secs, state=2 Since it is mostly the same IP repeating I'm assuming it's a client issue. Is that correct? What could cause this? Can we safely ignore it? Thanks, Bernhard

[Dovecot] Marking all mail in one folder of public mailbox as read
by Frerich Raabe 22 Oct '12

22 Oct '12

Hi, I'm running Dovecot 1.2.17 on FreeBSD 9 to serve an archive of a few internal mailinglists. The archive is implemented using a public namespace: namespace private { separator = / prefix = inbox = yes } namespace public { separator = / prefix = Lists/ location = maildir:/home/vmail/lists/Maildir:CONTROL=~/Maildir/lists:INDEX=~/Maildir/lists subscriptions = no } As you can see, the CONTROL/INDEX files are stored per-user to allow private \Seen flags. The different mailinglists are all sent to the 'lists' user which has a Sieve script to file them into different folders, so I have directories on my harddisk like /home/vmail/lists/Maildir/.somelist /home/vmail/lists/Maildir/.anotherlist Now, I'd like to mark the mail in *one* of those folders as \Seen by default. If the INDEX files weren't per-user, it would simply be a matter of using 'addflag "\Seen";' in the Sieve script of the lists user. Alas, this has no effect. Hence my question - how can I have the mail of just one mailinglist get marked as "read" for all users? So far, the only option I see is to add a second public namespace, with a different prefix - and this namespace doesn't use private CONTROL/INDEX files. However, I'd like to keep using the "Lists" prefix if possible to avoid too many changes to the clients. -- Frerich Raabe - raabe(a)froglogic.com www.froglogic.com - Multi-Platform GUI Testing

The dict is also needed for quota lookup from the database. The only thing which might be omitted is the global quota_rule since it is returned by the userdb/passwd in any case, but I'm not sure what happens if you only configure a "quota_rule2" without configuring a "quota_rule". > My outstanding issue is whenever I as the root mysql user update a > user's quota the other user also gets an update, I noticed with one > the messages column on the other user went from 0 to 2, another time > the quota value went up from 0 to 3500 it seems random. You should not be accounting the actual mailbox usage in the same virtual_users table as the quota is read from. Use *different* column or table name in your dict file where dovecot may write the current storage/message count. > dovecot-dict-sql.conf.ext > > map { > pattern = priv/quota/storage > table = virtual_users > username_field = user > value_field = quota value_field should be current_quota_storage (writable column) > } > map { > pattern = priv/quota/messages > table = virtual_users > username_field = user > value_field = quota_messages value_field should be current_quota_messages (writable column) > I'd like to know why these columns are updating. Dovecot stores the current storage and mailcount in there. These columns should be different from the columns defining the maximum limit. Regards Daniel

[Dovecot] still having difficulties with per-user quotas

Hello, I am trying to get per-user quotas working. My thanks to all who have helped so far. To recap I am running Dovecot 2.1 and Mysql where I've got my virtual users. All virtual users are under the system user vmail with a UID and GID of 5000. Looking over the wiki docs I've added a quota table and got the dict service working, I am not having problems with permissions or the login username and password, all that is working fine.

[Dovecot] Dovecot 2 and TCP-Keepalive
by Sven Hartge 20 Oct '12

20 Oct '12

Hi! I am about to migrate a perdition-based IMAP/POP3 proxy to Dovecot. Unfortunately some users are behind a firewall/NAT setup which throws away seemingly idle TCP connections sooner than the established default of 24 hours (more likely after 30 minutes ...) resulting in all kinds of weird client behavior. And unfortunately² this firewall/NAT setup is outside of my control and I have no means of correcting this (in my opinion) flawed configuration. Now, with perdition I was able to use the --tcp_keepalive option which totally solved the mentioned weird client behavior. My question is: does Dovecot2 use TCP-Keepalive on its sockets per default or do I need to enable it some way I have not yet discovered? The manual and wiki only talk about "keepalive" in connection with the IMAP protocol and IDLE and my C-fu is too weak to understand the source code. Grüße, Sven. -- Sigmentation fault. Core dumped.

[Dovecot] Question about salted hashes
by Tobias Maffert 19 Oct '12

19 Oct '12

Hello. I'm switching from b1gmail to my own setup which consists of Postfix+Dovecot+MySQL (and maybe VBoxAdm). There are two problems: - b1gmail is using unsalted MD5 hashes. Is there any good way to make my new setup backward compatible? So I don't have to force all of my 50k users to change their password. - How do I change my setup to salted SHA256 (or an even better algorithm). And how do I make the hashes compatible between Postfix, Dovecot, MySQL (and maybe VBoxAdm)?

[Dovecot] Emails from invalid local accounts
by Steven Kiehl 19 Oct '12

19 Oct '12

Hi, I'm using dovecot 1.2.9 in a postfix/dovecot setup and I'm having issues with receiving spam where the "from" header contains an address like accounting(a)mydomain.com. Is there some way I can filter out these emails coming from outside our network with an account associated with our network which doesn't exist? Do I just need to configure some custom process to evaluate these addresses, or is there some way either in dovecot or spamassassin to do this? Thanks, Steve K

[Dovecot] lmtp proxy logging
by Jack Bates 18 Oct '12

18 Oct '12

The logging on lmtp and lmtp proxy is pretty limited from what I can see. It seems to handle errors, Connect, Disconnect, and in the case of lmtp delivery, it logs where an email is saved to. The lmtp may be enough, "connect, saved user, saved user..., disconnect", but I was curious if it is worth while to add more info logging for the proxy, primarily which recipients are sent to which proxy. I was thinking of local patching it, but I'll generate up something more inline with official code if it is desired. My thought is to show 1 entry for each recipient, and the destination server chosen. If I recall correctly, the proxy code doesn't actually listen in on the conversation, so logging results would probably complicate the code. Jack

[Dovecot] Problem with process_limit
by FABIO FERRARI 18 Oct '12

18 Oct '12

Hello, i have a problem with the process_limit configuration. Occasionally, it happens that the dovecot.log shows this line: master: Warning: service(imap): process_limit reached, client connections are being dropped So I checked, the process number, with the command: ps auxwww | grep imap | grep -v login | wc -l and it shows 1024. Then, i edited the file /etc/dovecot/conf.d/10-master.conf and set the line process_limit = 1500 I checked if the dovecot had accepted the change with the command doveconf -n | grep process_limit and it shows process_limit = 1500 But it is dropping the connections when they reach 1024 anyway, the configuration parameter is totally ignored. Can anyone help? Am I editing the right parameter? thanks in advance Fabio Ferrari P.S. The version of the dovecot is dovecot-2.0.1-1_118.el5 on Red Hat Enterprise Linux Server release 5.8 (Tikanga).

[Dovecot] real_rip variable addition for dovecot 2.1.10
by Jack Bates 18 Oct '12

18 Oct '12

Timo, Please check the code. I didn't add it, but a real_lip might be useful for some people as well. Also, I notice that pop3-proxy is doing a different xsession than the imap proxy. Is there an xsession standard that is different between the two, or just an oversight in the code? Both send the remote address/port, but only imap proxy sends the local address/port. This patch declares long variable %{real_rip} so that a backend server can declare a different login_log_format_elements login_log_format_elements = user=<%u> method=%m rip=%r lip=%l pip=%{real_rip} mpid=%e %c This is primarily useful for backend servers to log both the rip, lip, and in case of xsession, the real rip. I haven't done extensive testing yet, but as long as nothing does anything weird elsewhere in the code, it should be good. http://www.brightok.net/jbates/dovecot-2.1.10-real-ip.patch dovecot: pop3-login: Login: user=<test>, method=PLAIN, rip=192.168.1.5, lip=::1, pip=::1, mpid=8665, secured Jack Bates

[Dovecot] Difference between Indexing and Rescan in FTS
by Fred Kilbourn 18 Oct '12

18 Oct '12

I've had squat running on dovecot 2.0 and have been updating all users mailbox indexes nighty via cron with this command: doveadm -v search -A text xyzzyx I've just updated to 2.1 and I'm migrating to lucene indexes, but reading the documentation I'm having a hard time understanding the semantic differences between indexing and rescanning. If I were to continue to run an all user all mailbox index every night, would that be appropriate? Would running this every night avoid the need to ever rescan? Should I run rescan instead of index? Should I run both rescan and index? In which order? Best Regards, FredK

Hi All, I keep going round in circles with this. I have quotas up and running but would like to add a couple of per user exceptions but can't figure out how to do it! I am using Open Xchange community edition on top of dovecot and tha tis showing the 200MB limit, if I change it in the dovecot.conf the change is reflected in open xchange, but can't figure out how to change for 1 user.

[Dovecot] Dsync clustering

I have not seen mention of using dsync for clustering Dovecot in some time on the mailing list, but I believe Timo was going to write a wiki page when v2.2 became more mature. Does this documentation exist yet, or are there any resources on what dsync replication is capable of at this point (looking on the wiki and google didn't reveal much)? Thank in advance.

Easy enough to test. It's non-RFC compliant as one poster points out, so unless you got a good reason to do this like lots of zombie pop3 processes, leave it alone.

[Dovecot] Dovecot sieve and duplicate email subjects
by Benjamin Thomas 17 Oct '12

17 Oct '12

Hi, I'm running a small email server with the help of iRedMail. I can manage sieve scripts from the Rouncube web interface or manually inside the user's personal sieve folder. I have an email account setup to receive automated tasks. Some of these "alerts" occur too often and they have the same subject line, but different senders. This is the rule I am currently using: ##CODE START## # rule:[AutoAlerts] if anyof ( header :matches "Subject" "AutoAlert Type1*", header :matches "Subject" "AutoAlert Type2*", header :matches "Subject" "AutoAlert Type3*" ) { fileinto "INBOX.AutoAlerts"; stop; } ##CODE END## I was wondering if it's possible to gracefully handle duplicate subjects lines (within a given time frame) with sieve filters ? Ideally, I would like the first email of the day with subject ""AutoAlert Type1..." to get moved to the subfolder given above. Subsequent "duplicate" emails would then go into a "duplicate" subfolder. Is this possible with sieve filters ? I could not find anything striking me as obvious while reading the page http://wiki.dovecot.org/LDA/Sieve. Thanks very much for your input.

[Dovecot] Dovecot failed logins delay all logins
by Dominic Malolepszy 17 Oct '12

17 Oct '12

Hi all, I have observed with my Dovecot setup that unique failed logins cause legitimate correct logins to be slowed. I am running two servers, each with two Dovecot instances, a Proxy with Director, and a backend Dovecot. I suspect that the backend instance is throttling connections from the same IP, and because I am running a Proxy, the backend will only see either of the two server IPs. I confirmed this by directly connecting to the backend, to bypass the proxy and rule it. I initiated dozens of unique failed logins from one IP and separately attempted to login from the same IP, and experienced an extended delay during login. At the same time a login from a different IP suceeded imediately. I see nothing in the logs suggesting some sort of process limits were exceeded, however I do see the following proc title for the backend auth process: "dovecot/auth [7 wait, 0 passdb, 0 userdb]" I have increased the mail_max_userip_connections to a very large value however I believe that setting is a per username/ip limit. Is there any sort of setting in Dovecot that I can configure that stops this authentication throttling per IP? Below is the configuration of the backend Dovecot instance. # 2.1.9: /etc/dovecot/dovecot.conf # OS: Linux 2.6.32-279.5.2.el6.x86_64 x86_64 Red Hat Enterprise Linux Server release 6.3 (Santiago) auth_cache_negative_ttl = 3 secs auth_cache_size = 100 M auth_cache_ttl = 10 mins auth_default_realm = example.com auth_failure_delay = 5 secs auth_mechanisms = plain login auth_verbose_passwords = sha1 auth_worker_max_count = 25 base_dir = /var/run/dovecot/ disable_plaintext_auth = no first_valid_gid = 12 first_valid_uid = 8 last_valid_gid = 12 last_valid_uid = 8 login_greeting = Hello there. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l mpid=%e %c mail_fsync = always mail_gid = mail mail_location = maildir:%h/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_plugins = " stats" mail_uid = mail mmap_disable = yes namespace { inbox = yes location = maildir:%h/Maildir prefix = INBOX. separator = . } passdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } protocols = pop3 imap service auth { unix_listener auth-userdb { group = mail mode = 0660 user = mail } } service imap-login { inet_listener imap { address = 0.0.0.0 port = 9143 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service imap { process_limit = 1000 vsz_limit = 256 M } service pop3-login { inet_listener pop3 { address = 0.0.0.0 port = 9110 } process_min_avail = 5 service_count = 0 vsz_limit = 256 M } service pop3 { process_limit = 1000 vsz_limit = 256 M } service stats { fifo_listener stats-mail { mode = 0600 user = mail } inet_listener { address = 127.0.0.1 port = 24242 } } ssl = no stats_memory_limit = 64 M userdb { driver = prefetch } userdb { args = /etc/dovecot/dovecot-ldap.conf driver = ldap } verbose_proctitle = yes protocol imap { imap_logout_format = bytes_read=%i bytes_send=%o mail_max_userip_connections = 1000 mail_plugins = " stats " } protocol pop3 { mail_max_userip_connections = 1000 } Dominic

[Dovecot] Problem with quota update in dovecot 1.2
by tower 16 Oct '12

Hi A have a problem with quota2 table, working under postfixadmin. When I login into imap server with thunderbird client everything works fine, quota is update when i receive a message, but when I move message to trash or any other folder value for messages field in table quota2 increases +1 instead decreases or have still this same value. Only if I close my imap client value descending -2. I wish to table quota2 will be updated immediately after any operation on inbox. Is there any mistake in my configuration?

[Dovecot] Plugin hooks in login process
by Simone Lazzaris 16 Oct '12

16 Oct '12

Hi all; I've setup dovecot (2.1.10) in a cluster configuration. We have two servers acting as frontend which authenticates users and proxy them to other two servers which handles the "real" work. Users credentials are on a mysql cluster; we have one master, in which read/write queries are processed, and many replicated slave, which process read-only queries. The frontend servers reads users credentials from the read-only mysql slaves. I'd like to execute a query once the client is verified to update the last login data. Right now, that query is executed on the backend servers, via a post-login service: protocols = imap service imap-postlogin { executable = script-login /usr/local/etc/dovecot/postlogin.sh unix_listener imap-postlogin { group = vchkpw mode = 0600 user = vpopmail } } service imap { executable = imap imap-postlogin process_limit = 2048 } Problem is, if I execute the update on the backend, I miss the information regarding the original IP, as I only see the IP of the proxies. I haven't been able to launch the postlogin service on the frontend, so I figured that I can try to write a plugin - that also seems to me the cleanest solution. Looking in the dovecot source code, I noticed that there aren't any hooks in the execution path used by the proxies; I am missing something ? I am the only one missing the presence of this hooks in the auth/proxy process ? I've also thought of a workaround for this problem. One way is to monitor the dovecot logs on the frontend and execute the update asyncronously. One other way is to query directly the main mysql server of the cluster and adjust the query making it call a stored procedure that updates the information in case of successful login. But I'd really prefer to create a plugin, that I'd be willing to share. I attach the configuration of the servers (front and back) generated via postfix -n. Thanks in advance for any help. -- Simone Lazzaris | Responsabile aree datacenter e VoIP Interactive Network srl | via Roggia Vignola 9, 24047 Treviglio (BG) Tel. 0363 1970352 | Fax 0363.1971971 | www.interactive.eu

[Dovecot] Dovecot deliver Segmentation fault when arrive the first message
by Alessio Cecchi 16 Oct '12

16 Oct '12

Hi, I have found this strange problem. I'm working with Debian 6, dovecot 2.1.9 and vpopmail-auth. LDA is configured and works fine but the problem is when the first message arrive "dovecot-lda" return a "Segmentation fault", the message is written to the user's Mailbox but the message remains, also, in the queue of qmail (deferral: Segmentation_fault/) and at the second attempt is delivered fine. If disable ACL (acl and imap_acl from mail_plugins) in dovecot.conf "Segmentation fault" go away. Moreover, without ACL at the first delivery folders like Sent, Drafts, Trash, Spam appear immediately. An example, new user: root@demo-vpop ~ # tree /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ -a /home/vpopmail/domains/qboxdns.it/cecchi2/Maildir/ ├── cur ├── maildirsize ├── new └── tmp

[Dovecot] Search for substring in header?
by Dave Abrahams 16 Oct '12

16 Oct '12

Hi, According to the IMAP spec (http://tools.ietf.org/html/rfc2060#page-37) if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. What am I doing wrong?

[Dovecot] [BUG] Lucene plugin breaks header substring search
by Dave Abrahams 16 Oct '12

16 Oct '12

According to the IMAP spec if I do a search for "TO isocpp.org" it should find all the messages whose To: field contains the string "isocpp.org", but dovecot is returning me an empty list. However, a search for "TO tm(a)isocpp.org" produces a long list of messages. This behavior is present if I *even load* the lucene fts plugin.

Re: [Dovecot] per-user quotas
by David Mehler 16 Oct '12

16 Oct '12

Hello, Thanks for your replies so far. Still having issues with per-user quotas. To my Mysql virtual_users table I've added a column quota_kb and for a test user I've added in a value of 250000 going for a 250 megabyte quota. I've tried various sql queries they're returning empty sets not pulling out the information needed. Thanks. Dave.

[Dovecot] fts = squat solr
by Dave Abrahams 16 Oct '12

16 Oct '12

I don't know if this was supposed to have changed with dovecot2, but http://wiki.dovecot.org/Plugins/FTS shows fts = squat solr so, since I have the lucene plugin—"fts = lucene" works by itself—I tried fts = squat lucene but: $ doveadm index '*' doveadm(dave): Error: fts: Failed to initialize backend 'squat lucene': Unknown backend So, is that syntax obsolete, is the wiki wrong, or am I doing something wrong? -- Dave Abrahams BoostPro Computing Software Development Training http://www.boostpro.com Clang/LLVM/EDG Compilers C++ Boost

[Dovecot] POP UIDL
by simon.buongiorno＠gmail.com 16 Oct '12

16 Oct '12

Hi I run a small mail server with Dovecot and postfix. Several of the accounts are popped by an external email provide I use, mostly out habit and also for a bit of redundancy. I have no details on that external server except that it uses exim. Lately, it's been repopping mail from accounts (mail is left on the server so I can use IMAP) at fairly frequent, but undetermined, intervals. Before I take it to them, I want to be sure it's not an error on my side. How can I be sure Dovecot does not have a problem with the UIDL list causing this external server to repop the mail? For the record, I'm not inclined to think it's a Dovecot issue, but since that's the bit I can fix, I'd like to be sure. Cheers Simon

Also some times one of the three users check the mail for this Account using imap (squirrel mail) And here comes the problem. suddenly all the three users are unable to check the mail And when the outlook express connect to the pop3 server, they are unable to disconnect And the outlook express keep asking "the server is not responding for 60 mins would you like to wait ? i checked /var/log/maillog, i can see the following errors dovecot: pop3(sales): Disconnected: Storage error during logout. to=<sales(a)domain.com>, orig_to=<sales(a)domain.,com>, relay=local, delay=357, delays=338/0.01/0/19, dsn=4.2.0, status=deferred (cannot update mailbox /var/mail/sales for user sales. unable to lock for exclusive access: Resource temporarily unavailable) When i used lsof | grep sales pop3 4278 sales 10u REG 8,3 22897673 12615705 /var/spool/mail/sales i went to /home/sales/mail/.imap/INBOX , but i didnot find any lock files -rw------- 1 sales sales 944 Oct 7 13:35 dovecot.index -rw------- 1 sales sales 49152 Oct 7 16:57 dovecot.index.cache -rw------- 1 sales sales 14044 Oct 7 16:57 dovecot.index.log 1- So what is exactly the problem? is the problem that three users are checking the same exact mail ? 2- is the problem that 2 users checking mail using pop3 and the third one checking it using imap insame time ? 3- is dovecot locking the inbox file while one of the users getting the mail ? 4- What is the cause of the problem ? Please help Regards Robert JR

[Dovecot] Where'd the Mail Go?
by John Reddy 16 Oct '12

16 Oct '12

Hi; I ran this: echo "Hello me" | mail -s "Dovecot test" $USER then created a bash script: for mbox in /var/mail/$USER /var/spool/mail/$USER ~/mbox ~/mail/* ~/*; do grep -q "Dovecot test" $mbox && echo "mbox: $mbox" done grep -q "Dovecot test" ~/Maildir/new/* 2>/dev/null && echo "Maildir: ~/Maildir" and ran it but couldn't find where the mail went. I checked /var/mail/my_user_name and it wasn't there, either. How do I find it? TIA, John

[Dovecot] Advanced dovecot tricks - spam review/release
by Marc Perkel 16 Oct '12

16 Oct '12

Hi, I'm looking for some advice to do a really advanced trick with Dovecot. I'm not sure if this can be done. I need to describe first. I have a spam filtering company that does front end spam filtering. (Junk Email Filter) I want to add a system where I store a copy of spam on a server and make it available to the customer to review and maybe resent on false positives. I know I could do something simple where I deliver all spam to a domain account and make it available to an administrator. Then if it's a false positive they would drag the message to a "resend" folder. I'll have something the checks the folder one a minute to pick up and resend. However What would be very cool is delivering the spam to individual accounts. So a user who logs in individually can see their own spam. But the admin for the domain would be able to see all users. Maybe the users would appear as folders? Then a master account (me) would be able to log in and see all the domains as folders and the users as folders inside the domains? One thing I can do is deliver the spam to 3 different places so it's visible on all levels. I'm just wondering if anyone out there has any ideas about that. And I'll need an authentication system.

In some of my maildrop filters I have rules with weighted scoring[1], but only to count headers (for example to count "Received:" header) ie. all these rules are of form "/pattern/:h,1" Can dovecot sieve do this?

13 Oct '12

HELP! I have installed sendmail, dovecot, and squirrel mail. The squirrel mail portion of it works just fine, but I would like to have Mozilla Thunderbird as a client. Whenever I try and connect to the server it says "Thunderbird failed to find the settings for your email account." We do have an MX record in DNS pointing to our server. We are using Ubuntu 12.0.4.1, and have Dovecot 2.2.6 sendmail version 8.14.4-2ubuntu2 We are doing this for a class project and it is due by Tuesday 10/16/2012.. Thanks, Justin

[Dovecot] dsync ignores ssh-agent
by Mark Hills 13 Oct '12

13 Oct '12

I use IMAP over SSH, in pre-auth. I wanted to use dsync to offline mail to my laptop. dsync v2.1.10 would always ask for my SSH key/passphrase, ignoring ssh-agent. The culprit is the env_clean() in the stack below. Reading the source, I saw DOVECOT_PRESERVE_ENVS. When used as follows in my script it enables dsync to find my ssh-agent: export DOVECOT_PRESERVE_ENVS="SSH_AGENT_PID SSH_AUTH_SOCK" dsync mirror ssh imap.example.com /home/mark/opt/dovecot/bin/dsync and it now works without asking for password every time. I'm posting here so that anyone else googling for the same problem will hopefully find this, as I couldn't find anything about this in the docs. Also I'm interested in why dsync so aggressively cleans the environment; I tried a naive removal of env_clean() but this breaks basic functions. With this dsync is working very well for offline mail -- combined with alpine and a local exim for the outbound queue :) Thanks -- Mark Breakpoint 2, env_clean () at env-util.c:59 59 if (clearenv() < 0) (gdb) bt #0 env_clean () at env-util.c:59 #1 0xb7df10fc in master_service_env_clean () at master-service.c:454 #2 0xb7df26d4 in master_service_exec_config (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:103 #3 0xb7df29be in config_exec_fallback (service=0x809e7d0, input=0xbffff7e4) at master-service-settings.c:153 #4 0xb7df2b65 in master_service_open_config (service=0x809e7d0, input=0xbffff7e4, path_r=0xbffff780, error_r=0xbffff7d8) at master-service-settings.c:206 #5 0xb7df3130 in master_service_settings_read (service=0x809e7d0, input=0xbffff7e4, output_r=0xbffff7dc, error_r=0xbffff7d8) at master-service-settings.c:345 #6 0x0805c672 in doveadm_read_settings () at doveadm.c:275 #7 0x0805c7d6 in main (argc=5, argv=0x809e1c0) at doveadm.c:342
