The parentheses in the subject are due to referral to this discussion on the mailing list: http://dovecot.org/list/dovecot/2012-February/063851.html At first I thought I found the problem, but then realized this was 2012 and the suggested patch already is applied in dovecot. I also have segault messages in my kernel log; not too many, but it was enough to dig for it: > Wed Jun 25 08:29:05 2014 auth[17590]: segfault at 10 ip 00007f02ad5e8e56 sp 00007fff932f9250 error 4 in auth[7f02ad5d3000+40000] > Mon Jun 30 16:11:41 2014 auth[12501]: segfault at 10 ip 00007fc6a1fefe56 sp 00007fff276e6ea0 error 4 in auth[7fc6a1fda000+40000] > Sat Jul 5 13:11:32 2014 auth[15603]: segfault at 10 ip 00007f6447a6be56 sp 00007fff09c48020 error 4 in auth[7f6447a56000+40000] > Tue Jul 8 05:08:21 2014 auth[30071]: segfault at 10 ip 00007ff22656ae56 sp 00007fff26b017f0 error 4 in auth[7ff226555000+40000] > Mon Jul 21 14:25:28 2014 auth[30918]: segfault at 10 ip 00007fe1fc817e56 sp 00007fff7e654f20 error 4 in auth[7fe1fc802000+40000] <--- > Wed Aug 13 18:56:31 2014 auth[27593]: segfault at 10 ip 00007ffbf8ce8e56 sp 00007fffe0157f70 error 4 in auth[7ffbf8cd3000+40000] > Wed Aug 13 18:57:59 2014 auth[24264]: segfault at 10 ip 00007f2df31bde56 sp 00007fff094263c0 error 4 in auth[7f2df31a8000+40000] The last 2 entries are a result of me being able to reproduce the problem, the 3rd last is the only one I was able to track down (due to log rotation) I tracked the problem down to a contact form of a website of one of my customers. whenever used, the segfault gets triggered.

The used CMS is PyroCMS (v2.2.3) - the version is not up2date, but nevertheless the CMS might be the one to blame, a service should not segfault. Some packages are to be updated, as well as the CMS; but I am willing to wait to provide information, which leads to the problem, as I cannot switch between different versions on my productive system for the sake of gaining debug information. I hope that someone has any kind of clue and is willing to resolve that issue with me, asking me for the necessary information to do so. Thanks in advance!

Multiple Passdb's - Order
by Jean-Louis Dupond 15 Aug '14

15 Aug '14

Hi, Today I upgraded my dovecot to a newer version (2.2.9 debian wheezy-backports) At that moment I also reconfigured the whole thing a bit nicer. Now I stumbled on the following issue. In my configuration I use 2 backends (LDAP & passwd-file). passdb { args = scheme=CRYPT username_format=%u /etc/dovecot/users driver = passwd-file } passdb { args = /etc/dovecot/dovecot-ldap.conf.ext driver = ldap } userdb { args = uid=vmail gid=vmail home=/var/vmail/%d/%n driver = static } Now this worked fine before. But if I tested it, LDAP logins worked, and passwd-file logins failed. Failed log (user is only in the passwd-file): Aug 01 21:31:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_pgsql.so Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_sqlite.so Aug 01 21:31:55 auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 01 21:31:55 auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so Aug 01 21:31:55 auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat Aug 01 21:31:55 auth: Debug: passwd-file /etc/dovecot/users: Read 10 users in 0 secs Aug 01 21:31:55 auth: Debug: auth client connected (pid=5516) Aug 01 21:31:55 auth: Debug: client in: AUTH 1 PLAIN service=imap secured session=c34kcZb/uwBbtKLu lip=xxx rip=xxxx lport=993 rport=52411 Aug 01 21:31:55 auth: Debug: client passdb out: CONT 1 Aug 01 21:31:55 auth: Debug: client in: CONT 1 xxxxx (previous base64 data may contain sensitive data) Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: ldap(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): pass search: base=uid=info(a)xxx.com,ou=mail,dc=dupie,dc=be scope=subtree filter=(&(objectClass=posixAccount)(uid=info(a)xxx.com)) fields=uid,userPassword Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:31:55 auth: Debug: passwd-file(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): lookup: user=info(a)xxx.com file=/etc/dovecot/users Aug 01 21:31:57 auth: Debug: client passdb out: FAIL 1 user=info(a)xxx.com temp Aug 01 21:31:57 auth: Debug: client in: AUTH 2 PLAIN service=imap secured session=c34kcZb/uwBbtKLu lip=xxx rip=xxx lport=993 rport=52411 resp=xxx (previous base64 data may contain sensitive data) Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:32:01 auth: Debug: ldap(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): pass search: base=uid=info(a)xxx.com,ou=mail,dc=dupie,dc=be scope=subtree filter=(&(objectClass=posixAccount)(uid=info(a)xxx.com)) fields=uid,userPassword Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): miss Aug 01 21:32:01 auth: Debug: cache(info(a)xxx.com,xxx,<c34kcZb/uwBbtKLu>): hit: {CRAM-MD5}19192922..... Aug 01 21:32:03 auth: Debug: client passdb out: FAIL 2 user=info(a)xxx.com temp As you see it returned a FAIL, but the password was retrieved from the users file (see the cache hit). Now I changed the order of the passdb's in my config, to make passwd-file come first, and then LDAP. And what happend now, it started working ...

It works fine now, but it not clear to me why the order is so important. Could somebody explain this? Or is this some bug? Thanks Jean-Louis

Cannot use dovecot with vpopmail and sendmail
by Matthias Fechner 15 Aug '14

15 Aug '14

Hi, I setup a configuration that will use sendmail with dovecot as imap/pop3 service and vpopmail as backend to handle virtual users and store email there. For this I created a dovecot.m4 as described in the wiki, it looks like: ######################*****############## ### DOVECOT Mailer specification ### ##################*****################## Mdovecot, P=/usr/local/libexec/dovecot/dovecot-lda, F=l59DFMPhnu, S=EnvFromSMTP/HdrFromSMTP, R=EnvToSMTP/HdrFromSMTP, M=51200000, U=vpopmail:vchkpw, T=DNS/RFC822/X-Unix, A=/usr/local/libexec/dovecot/dovecot-lda -d $u Then I added to my .mc file: MAILER(dovecot) I added to my mailertable: dovecot.fechner.net dovecot:dovecot I create one entry in the virtusertable to catch a email and forward it to dovecot (all other email have to handled by another imap server till dovecot is running fine): dovecot(a)fechner.net idefix(a)dovecot.fechner.net I created a domain and a user in vpopmail to catch idefix(a)dovecot.fechner.net. If I execute: doveadm auth test idefix(a)dovecot.fechner.net Password: passdb: idefix(a)dovecot.fechner.net auth succeeded extra fields: user=idefix(a)dovecot.fechner.net So I think the first part is fine. But if I try to sent an email to dovecot(a)fechner.net I get the error message: Aug 14 21:48:34 anny dovecot: lda(idefix(a)dovecot.fechner.net): Fatal: setuid(89(vpopmail) from userdb lookup) failed with euid=1002(idefix): Operation not permitted (This binary should probably be called with process user set to 89(vpopmail) instead of 1002(idefix)) Aug 14 21:48:34 anny sendmail[94303]: s7EJXgma087740: to=<dovecot(a)fechner.net>, ctladdr=<idefix(a)anny.lostinspace.de> (1002/0), delay=00:14:52, xdelay=00:00:00, mailer=dovecot, pri=120389, relay=dovecot, dsn=4.0.0, stat=Deferred: dovecot mailer (/usr/local/libexec/dovecot/dovecot-lda) exited with EX_TEMPFAIL It seems to be a problem with dovecot-lda but I have no idea what is wrong. The user is set in the .m4 file and permission/group/user is set in the auth socket correctly.

Trying Dovecot Replication with dsync
by Minhas Listas 14 Aug '14

14 Aug '14

Hi, I have a failover cluster for mail server with: Ubuntu12.04 + DRBD (for block replication) + Ext4 filesystem + Dovecot-2.0.19-2 with Mdbox It works fine with ~50k accounts. My cluster design: http://adminlinux.com.br/cluster_design.txt I plan to test Dovecot Replication with dsync to build an active/active cluster with load balancing. Can anyone direct me to some literature? A tutorial for example. I'm installing a cluster (for tests) with Ubuntu 14.04 + Ext4 filesystem (without Drbd) + Dovecot-2.2.9-1ubuntu2.1. My conf is in: http://adminlinux.com.br/replication-doveconf.txt I'm following this doc http://wiki2.dovecot.org/Replication but I'm getting some errors: 1) Aug 14 15:39:34 ceph1 dovecot: imap(account=domaintest.com): Error: open(/var/run/dovecot/replication-notify-fifo) failed: Permission denied What is the correct perms for /var/run/dovecot/replication-notify-fifo ?

Quota Help
by user7743 14 Aug '14

14 Aug '14

Hi all, First post here so hopefully I get all the required information correct. I am running a mail server on Debian, its consists of Postfix (2.9.6-2), Dovecot (2.1.7) and MySQL (5.5). Basic stuff is all working find so I decided to try and implement quotas. This is working to an extent but not properly and I am a little lost so looking for some help. In my configuration the default mailbox quota is set to "*:storage=100M". When I create a mailbox with 250M specified in the database, dovecot is applying the default quota rather than that specified in the database. So in the database I have a test user with the following entry password,email,quota_kb [hash], test(a)example.org, 25000 If I turn debugging on for mail and auth I see the following logged when the user logs in (logs pasted at the end in a bid to maintain some readability) If I check the quota with doveadm I get the limit back of 102400 which is the default mailbox size rather than that from the database. doveadm quota get -u test(a)example.org Quota, name, Type, Value, Limit, % User quota, STORAGE, 19139, 102400, 18 User quota, MESSAGE, 567, - I can't quite figure out where I am going wrong in terms of getting the database value to supersede the default value set in 90-quota.conf. I did read one thing in the quota documentation on the dovecot website (http://wiki2.dovecot.org/Quota/Configuration) that I didn't get and this might be where I am going wrong but can't check. It says "Check that dovecot-lda is called with -d parameter." Where would this be configured and where could I check? Below are some other inputs - hopefully they help. ### Debug logs at login Aug 14 14:06:24: auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 14 14:06:24: auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 14 14:06:24: auth: Debug: auth client connected (pid=8090) Aug 14 14:06:24: auth: Debug: auth client connected (pid=8093) Aug 14 14:06:24: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=2QDLu5UAKAAuBSdf#011lip=99.99.99.99#011rip=55.55.55.55#011lport=993#011rport=50216 Aug 14 14:06:24: auth: Debug: client out: CONT#0111#011 Aug 14 14:06:24: auth: Debug: client in: AUTH#0111#011PLAIN#011service=imap#011secured#011session=ZBnLu5UAKQAuBSdf#011lip=99.99.99.99#011rip=55.55.55.55#011lport=993#011rport=50217 Aug 14 14:06:24: auth: Debug: client out: CONT#0111#011 Aug 14 14:06:24: auth: Debug: client in: CONT<hidden> Aug 14 14:06:24: auth-worker(8095): Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth Aug 14 14:06:24: auth-worker(8095): Debug: Module loaded: /usr/lib/dovecot/modules/auth/libdriver_mysql.so Aug 14 14:06:24: auth-worker(8095): mysql(127.0.0.1): Connected to database mailserver Aug 14 14:06:24: auth-worker(8095): Debug: sql(test.example.org,55.55.55.55): query: SELECT email as user, password FROM users WHERE email='test.example.org';

Domain name lost for SASL
by Dominic Wong 13 Aug '14

13 Aug '14

Hi, I'm trying to set up Postfix + Dovecot (2.0.9) + PostfixAdmin on CentoOS (the standard amazon machine image) and am having problems with my SMTP user authentication. Turning on auth debugging I can see the username is losing the first part of the domain so one(a)two.three becomes one.three dovecot: auth: Debug: sql(one.three, ... ): query: SELECT username AS user,password FROM mailbox WHERE username = 'one.three' AND active='1' I don't know if it's postfix or dovecot which is trimming the username, any tips on what causes this would be greatly appreciated. Thanks

Defer email via LMTP when there is 'no space left on device' instead of rejecting it
by Christian Rohmann 12 Aug '14

12 Aug '14

Hello dovecot-users, (This problem was being discussed a little in this thread from 2011: http://www.dovecot.org/list/dovecot/2011-May/059009.html) I noticed (using LMTP) that Dovecot handles 'no space left on device' just like an 'over-quota', if I read this part of method "static int client_deliver(struct client *client, const struct mail_recipient *rcpt, struct mail *src_mail, struct mail_deliver_session *session)" "lmtp/commands.c" correctly: --- cut --- [...] else if (storage != NULL) { error = mail_storage_get_last_error(storage, &mail_error); if (mail_error == MAIL_ERROR_NOSPACE) { client_send_line(client, "%s <%s> %s", dctx.set->quota_full_tempfail ? "452 4.2.2" : "552 5.2.2", rcpt->address, error); } else { client_send_line(client, "451 4.2.0 <%s> %s", rcpt->address, error); } ret = -1; [...] --- /cut --- In consequence this means the configuration option quota_full_tempfail is applied in both cases. But to me there is a major difference between a full disk (a.k.a "admin fucked up") and over-quota (a.k.a. "user has simply too much stuff in his mailbox"). So I would like to be able tell Dovecot to reject messages due to full mailboxes, but simply defer those that cannot be stored due to a full disk (which I am to blame for). To me this should result in two separate configuration options for the two problem root-causes: quota_full_tempfail storage_full_tempfail Or did I simply miss or completely misunderstood anything here? Regards Christian

Sieve: Saving "pristine" messages for backups and spam training
by Jeff Rice 12 Aug '14

12 Aug '14

Hello, I'm trying to work out a way to have my Sieve filter save a "pristine" version of email messages as a backup, primarily to use for training the spam filter. I would like is to have every message saved into a single, site-wide directory (in the global sieve) before being processed additionally and delivered. The messages in that directory will be used to train the spam filter without having to worry about removing Spamassassin headers and so forth. I thought fileinto :copy might do what I wanted, but this creates a backup directory individually for each user. That's unmanageable for the spam training process I use. redirect *could* work, but that adds a header during the process so the email saved would not be "pristine". I'm thinking of using the extprograms plugin to pipe to a program that will do a simple copy. That feels very hackish, however, and I'm hoping there is a more elegant solution. Am I missing something obvious here? Thanks! Jeff

This seems weird, as I would expect it to be more or less randomly distributed over that interval. Does this happen at the top of each minute? If what you observe is true, the only situation I can think of that would cause this is a bunch of POP3 fetch clients running as a cron job synchronized to a minute grid (i.e seconds=0).

Options mail_nfs_storage and mail_nfs_index not in 2.2(.13) example config anymore?
by Christian Rohmann 11 Aug '14

11 Aug '14

Hey dovecot-users, did I miss anything anywhere about the configuration variables "nfs_storage" and "mail_nfs_index" being removed from the example configuration in 2.2? In 2.1 they where both in 10-mail.conf commented out and set to their default "no". But with 2.2 they are not in any of the exmaple config files anymore. doveadm is still showing the variables and they can be used as ever still. Just wondering if I missed something and this should be configured differently on 2.2 now. Regards Christian

poolmon improvements
by Timo Sirainen 11 Aug '14

11 Aug '14

I've been planning to improve poolmon failure checking for a long time already, but I still haven't managed to get to it. Maybe somebody else has more time, so here's a feature request for anyone to implement: poolmon currently gives up immediately if the first check to any service fails. It really should be trying multiple times over multiple seconds before giving up. I think ideally it would be: - Individual check timeout could still be the default 5 seconds - Add full check time setting, which could be e.g. 15 seconds. If all checks fail during this time then disable the host. - If request fails because connection gets rejected, retry quickly, e.g. after 0,1 seconds - If check fails because of protocol errors, wait for a long time, e.g. 1 second So this would avoid backend being removed in situations where it really shouldn't be removed: - Dovecot restarts - Dovecot reloads - load spikes and other random issues that cause temporary problems Especially the load spike is an annoying issue which my plan doesn't even fully solve. The solution to fix a heavily overloaded cluster isn't really to start removing all of its backends that are busy working..

Dovecot v2.2 FTS is not indexing "text/html" emails...
by Akash 09 Aug '14

09 Aug '14

Hi, I am not sure its intended or a fault in the newest Dovecot versions. I have been using Dovecot v1.2.15 on Debian squeeze and FTS is working as expected. When I search a quoted string "very good", I get 107 results including plain and HTML emails which have this phrase. In order to compare the benefits of lucene over squat, I recently started testing dovecot v2.2.13 on Debian Sid with the same maildir content. But now the same search "very good" yielded just 8 results. I thought it could be some problem with lucene so I tried switching to squat and got 107 results again. After this I deleted the old squat search index files created by v1.2.15 and re-indexed the mail-box by using doveadm index command. Now the same squat search is giving 8 results just as lucene. So I have realized that its not a problem with just lucene but FTS in newer dovecot isn't indexing those emails which have Content-type as text/html. Thus if a mail is like this: Content-Type: text/html <b>He is very good.</b> It isn't shown in search by the squat indexes created using dovecot v2.2.13. I have done further testing on some sample emails which confirmed this behavior. Why is this so? -Regards, Akash

Throttling pop3-login connections
by Alex 09 Aug '14

09 Aug '14

Hi, I have a fedora20 system with dovecot-2.2.13 running various services, including pop3. I'm noticing some users are frequently hamming pop3, and wondered if this was normal, or something I should be investigating? Aug 8 14:05:20 email dovecot: pop3-login: Login: user=<user1>, method=PLAIN, rip=97.77.115.121, lip=192.168.1.1, mpid=30509, session=<DnRtDCIAUQBhTXN5> Aug 8 14:05:21 email dovecot: pop3(user1): Disconnected: Logged out top=0/0, retr=0/0, del=0/15, size=5693601 So it is immediately followed by a logout, but when there are 50 of them successively in a five minute period, I wondered if it is creating unnecessary overhead on the system? I suppose this most likely is how they have their email client configured, but wondered if some throttling would be necessary? Any advice would be most appreciated. Thanks, Alex

I've been trying for some days to get postfix + dovecot + pigeonhole/sieve working on a CentOS-7 home server. I think I may have detected the problem; I read in /var/log/maillog Aug 4 11:29:13 alfred postfix/lmtp[14871]: 9C04C220A99: to=<tim(a)localhost.gayleard.eu>, orig_to=<tim@localhost>, relay=alfred.gayleard.eu[private/dovecot-lmtp], delay=971, delays=971/0.03/0.02/0.1, dsn=4.3.0, status=deferred (host alfred.gayleard.eu[private/dovecot-lmtp] said: 451 4.3.0 <tim(a)localhost.gayleard.eu> Internal error occurred. Refer to server log for more information. (in reply to RCPT TO command)) (I've split one long line here.) 1) I see that the permissions on /var/spool/postfix/private/ are [tim@alfred ~]$ ls -ls /var/spool/postfix/ 4 drwx------. 2 postfix root 4096 Aug 4 11:30 private The socket dovecot-lmtp setup by postfix is in this directory; does dovecot need permission to access this? 2) I see that this mail (a test email from me) was deferred. What exactly does this mean? Where is the mail stored? I couldn't find it anywhere. (It has already been brought to the server by fetchmail.) 3) Am I right in thinking that there are 2 alternatives to dovecot/sieve a) amavisd-new with postfix + spamassassin b) postfix + procmail ? 4) I remember seeing a posting (probably not in this mailing list) describing how one can trace the progress of email through the server. Unfortunately I didn't note the URL, and now cannot find it. Does anyone have a pointer to such a document? As will probably be obvious, I am not at all clear how postfix and dovecot fit together if one introduces lmtp. I take it that without lmtp (or similar) postfix just delivers email to ~/Maildir/cur (in my case), and dovecot is not involved at all until a client (KMail in my case) looks at email? -- Timothy Murphy e-mail: gayleard /at/ eircom.net School of Mathematics, Trinity College, Dublin 2, Ireland

Dovecot, Thunderbird and messages in wrong folder
by Gerhard Wiesinger 08 Aug '14

08 Aug '14

Hello, Sometimes it happens that messages (e.g. one or two) appear in wrong folders in Thunderbird (latest version, also past versions, different computers, also Earlybird). When I repair the folder (folder/Settings/Repair Folder) in Thunderbird, the folder is correct then. It happens on my new server with Fedora 20, Dovecot 2.2.13 and Maildir but it also happened on my old server with Fedora 1, Dovecot 2.2.13 and mbox. Has anyone the same issue? Any guess whether it might be a thunderbird or dovecot issue? Anyone has the same issues with thunderbird and a different IMAP server (e.g. cyrus)? Thank you.

Dovecot and remote SASL Client via TLS
by Gerhard Wiesinger 08 Aug '14

08 Aug '14

Hello, Is it possible to configure Dovecot as SASL client for central authentication (also remotely via TCP/TLS)? Following use case: IMAP server (host 1) <=> Windows Domain Controller and /etc/shadow authenticator via pam (host2) Should work as: IMAP server (host 1) <=> SASL Client via TLS <=> Network <=> SASL Server via TLS <=> Local SASL via pam <=> Windows Domain Controller and /etc/shadow authenticator via pam (host2) Thank you. Ciao, Gerhard -- http://www.wiesinger.com/

invalid/unknown path to storage
by Benjamin Connelly 08 Aug '14

08 Aug '14

Am I correct: pigeonhole now wants the symlink to the filter file to use an absolute path instead of the relative paths we had? i.e.) sieve-filterfile@ -> /home/mail/domain/user(a)domain/roundcube.sieve instead of sieve-filterfile@ -> roundcube.sieve Dovecot logs these: dovecot: managesieve(user(a)domain.org): Warning: sieve-storage: Active sieve script symlink /home/mail/domain.org/user(a)domain.org/sieve-filterfile is broken: invalid/unknown path to storage (points to roundcube.sieve). and the debug log: Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: Pigeonhole version 0.4.3 initializing Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve: include: sieve_global_dir is not set; it is currently not possible to include `:global' scripts. Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using active sieve script path: /home/mail/domain.org/user(a)domain.org/sieve-filterfile Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using sieve script storage directory: /home/mail/domain.org/user(a)domain.org/ Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: using permissions from /home/mail/domain.org/user(a)domain.org/: mode=0700 gid=-1 Jul 29 15:37:59 managesieve(user(a)domain.org): Debug: sieve-storage: relative path to sieve storage in active link: I found if I manually delete a symlink and replace it using the full path: sieve-filterfile -> /home/mail/domain.org/user(a)domain.org/roundcube.sieve then everybody is happy. So I'm looking to make a configuration change (and then change all existing symlinks.) I just wanted to check with the list about the two settings we return as part of the user_query: concat(homedir, maildir, 'sieve-filterfile') as sieve, concat(homedir,maildir) as sieve_dir In testing it seems like changing 'sieve' to return not the whole path but just the link name, actuall causes pigeonhole to properly make the symlink with full path! Does this seem right? FreeBSD (8.4) dovecot-pigeonhole (0.4.3_1) dovecot2 (2.2.13_3) Benjamin
