Dovecot with LDAP/AD has problem with uid/gid
by Luca Bertoncello 02 Apr '16

02 Apr '16

Hi list! I have a Server connected to an AD and I need to configure Dovecot to authenticate the users against the AD (with password and GSSAPI). Now I'm trying to connect Dovecot to the AD with password. The authentication works, but I always got this error: Apr 2 13:03:49 mail dovecot: pop3-login: Login: user=<lucabert>, method=PLAIN, rip=192.168.50.1, lip=192.168.50.3, mpid=3508, session=<ZWJDc34vDgDAqDIB> Apr 2 13:03:49 mail dovecot: pop3(lucabert): Error: stat(/var/spool/mail/lucabert/tmp) failed: Permission denied (euid=10001(lucabert) egid=10000(domain users) missing +x perm: /var/spool/mail/lucabert, dir owned by 1005:8 mode=0700) Apr 2 13:03:49 mail dovecot: pop3(lucabert): Error: Couldn't open INBOX: Internal error occurred.

Of course the Mailboxes have user 1005 and group 8. Can someone help me? Thanks Luca Bertoncello (lucabert(a)lucabert.de)

SIS deduplication fails to create intermediate directories and funny permissions
by Jesus Cea 01 Apr '16

01 Apr '16

I have configured my system to use SIS, sharing the same same storage for all users, and offline deduplication. I have this in my "root" cron: """ 53 1 * * * /usr/local/bin/doveadm purge -A 16 * * * * /usr/local/bin/doveadm sis deduplicate /home/dovecot/buzones/attachments /home/dovecot/buzones/attachments/queue """ Yes, it is launched as "root" but I would expect doveadm drop privileges as soon as possible. This is working great, but from time to time I get this error message: """ Your "cron" job on babylon5 /usr/local/bin/doveadm sis deduplicate /home/dovecot/buzones/attachments /home/dovecot/buzones/attachments/queue produced the following output: Error: mkdir(/home/dovecot/buzones/attachments/dc/62/hashes) failed: No such file or directory """ Looks like doveadm is trying to create the "hashes" directory but the parent "62" doesn't exits yet. If I create that directory by hand and set permissions correctly, everything (seems to) work. Talking about this, I see something strange wit the permissions. All files and directories in SIS are created with "dovemail" user and group EXCEPT the "hashes" directory inside the newly created directory. That is: When I get the error message, I have this: """ drwx------ 7 dovemail dovemail 7 Apr 1 13:28 . drwx------ 237 dovemail dovemail 237 Mar 24 20:09 .. drwx------ 3 dovemail dovemail 3 Feb 29 02:30 1d drwx------ 3 dovemail dovemail 3 Mar 9 01:53 7f drwx------ 3 dovemail dovemail 3 Feb 29 02:30 88 drwx------ 3 dovemail dovemail 3 Feb 29 02:30 8d """ I create the missing directory by hand and change permissions.

default namespace
by Nerijus Baliunas 01 Apr '16

01 Apr '16

Hello, With no namespace settings and dovecot 2.0.9 I get the following listing: a LIST "" "*" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasNoChildren) "." "INBOX" a OK List completed. Then I add the namespaces: namespace inbox { separator = . prefix = inbox = yes hidden = no list = yes subscriptions = yes } namespace compat { separator = . prefix = INBOX. inbox = no hidden = yes list = no alias_for = } Then list output changes: a LIST "" "*" * LIST (\HasNoChildren) "." "Trash" * LIST (\HasNoChildren) "." "Sent" * LIST (\HasChildren) "." "INBOX" a OK List completed. INBOX now has \HasChildren, while before it had \HasNoChildren. How can I make it \HasNoChildren?

Multiple IMAP Mailboxes and one collection folder
by Dieter Knopf 31 Mar '16

31 Mar '16

Hello, we use many IMAP folders and now we are searching for a way to display all mails inside this folders in one collecting folder. The advantage for us would be the possibility to view all new incoming mails in one folder. It would be possible to use the standard MAIL App on the iOS without problems. I could simply make a copy of all mails in one folder with Sieve, but then the Per-user Seen Flag would be useless, because the mail inside the folder is still unread. Is there a way to show some way of collecting folder for every user? Thanks Dieter

Dovecot plugin pthread issue
by qmail＠top-consulting.net 31 Mar '16

31 Mar '16

I am using FreeBSD 10.1 and Dovecot 2.2.22 with the Openchange plugin - https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu… (https://github.com/openchange/openchange/tree/master/mapiproxy/services/plu…) The plugin compiles just fine and works up until when it tries to create a socket using nanomsg, which uses a pthread_create() call. At that point dovecot-lda just hangs indefinitely. I've read that -pthread must be included in all the components that might end up using it. So checking with ldd: nanomsg does include libthr ( pthread equivalent in FreeBSD ) openchange plugin also includes libthr dovecot-lda doesn't include libthr Would dovecot-lda also need to be compiled with -pthread ? Is it safe ? How can it be done ? Thank you!

Dovecot-LMTP and LDAP: passdb doesn't support credential lookups
by Niols 30 Mar '16

30 Mar '16

Hello, Sorry, this might be a newbish question, but I really can't get the answer by myself. I'm trying to setup a mail server using LDAP to authenticate users, and I keep receiving the errors: passdb doesn't support credential lookups passdb doesn't support lookups, can't verify user's existence when I send test mails to (existing) users. I'm already using the LDAP server for other purposes, and it's working fine. I can't (or I don't want to) give read access to the userPassword attribute, so I want to use a authentication bind: http://wiki.dovecot.org/AuthDatabase/LDAP/AuthBinds I've already managed to have postfix working with this LDAP server, the users (and their aliases) are correctly recognized. Postfix then sends the mails to Dovecot (2.2.13, Debian Jessie's version) with dovecot-lmtp. Here is my /etc/dovecot/conf.d/auth-ldap.conf.ext. I use the static driver for userdb, and the LDAP driver for passdb. passdb { driver = ldap args = /etc/dovecot/dovecot-ldap.conf.ext } userdb { driver = static args = uid=mail gid=mail home=/var/mail/%u } Here is my /etc/dovecot/dovecot-ldap.conf.ext file. hosts = localhost ldap_version = 3 dn = cn=dovecot,ou=services,dc=niols,dc=fr dnpass = a-random-password auth_bind = yes base = ou=people,dc=niols,dc=fr pass_filter = (&(objectClass=inetOrgPerson)(mail=%u)) I haven't set the user_filter and user_attrs values, since I thought these would only be usefull for userdb. I haven't set the pass_attrs value, since I don't see why it would be needed (I just need to be able to bind my user, right?). I can't auth_bind_userdn since the e-mail address aren't necessarily related in any way to the user dn. I assumed %u was going to be replaced by the user's full e-mail address. I tried to play a bit with these values to find a working configuration, without success. I tried to search myself on the LDAP server, using the provided dn and dnpass, and I succeeded. I tried to activate debug logs, but that didn't give me much more information (full debug log at the end of this e-mail). I think the problem is that passdb cannot find the user on the LDAP server, but I don't know why. I believe the problem is lying in my non-comprehension of what userdb and passdb actually do. I tried to find out by myself, and I'm here because I didn't manage to do so. I'm sorry if this post looks stupid. Any help and any comments of any kind would be greatly appreciated. Regards, Niols PS: Here is the full debug log that I get after sending a test message to test(a)niols.net (.net vs. .fr: this is not a mistake, I use my .net domain for testing purposes while I use my .fr domain for eveyday life) with swaks: lmtp(3208): Connect from local auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Loading modules from directory: /usr/lib/dovecot/modules/auth auth: Debug: Module loaded: /usr/lib/dovecot/modules/auth/libauthdb_ldap.so auth: Debug: Read auth token secret from /var/run/dovecot/auth-token-secret.dat auth: Debug: LDAP initialization took 0 msecs auth: Debug: master in: USER 1 test(a)niols.net service=lmtp auth: Debug: ldap(test(a)niols.net): passdb doesn't support credential lookups auth: Error: static(test(a)niols.net): passdb doesn't support lookups, can't verify user's existence auth: Debug: userdb out: FAIL 1 lmtp(3208): Error: user test(a)niols.net: Auth USER lookup failed lmtp(3208): Disconnect from local: Successful quit

Would be great if someone could please point me to alternative locations for authentic RPMs

talloc access after free error ntlmssp_server.c:457
by J Landwehr 30 Mar '16

30 Mar '16

Our new/fresh dovecot imap installation on CentOS (latest from yum repository, which is 2.2.10) is locking up with a panic on a consistent basis and denying service to subsequent clients. The behavior is repeatable. Have spent weeks debugging and trying different configurations with no success. Specific /var/log/maillog error messages are: 12:06:54 dovecot: auth: Error: talloc: access after free error - first free may be at ../auth/ntlmssp/ntlmssp_server.c:457 12:06:54 dovecot: auth: Error: Bad talloc magic value - access after free 12:06:54 dovecot: auth: Error: PANIC (pid 2570): Bad talloc magic value - access after free Our configuration is based on the instructions for NTLM authentication with our Windows 2012R2 AD/Domain server: http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm <http://wiki2.dovecot.org/HowTo/ActiveDirectoryNtlm> Here are the steps to reproduce: 1. Fresh boot of CentOS server, only configured for postfix/dovecot 2. Connect with Outlook 2016 12.0.4312.1000 32bit on Win7 via IMAP to this dovecot server 3. Any existing and new mail loads in OK to inbox - so authentication is working OK to AD domain server 4. Send an email to someone from Outlook 5. SMTP process completes, message is delivered - 6. dovecot immediately panics on servers, Authentication to dovecot no longer works 7. <systemctl restart dovecot> will hang until a <kill -9> on the “dovecot/auth” PID is performed The issue is with steps 6/7 immediately after 4/5- and is intermittent. Steps 1-3 always work OK, as do 4-5. Further, inbound emails received on this server when no IMAP client is running are always received just fine and dovecot doesn’t hang. Sometimes I have to send a few email messages with steps 4/5 before the issue with 6/7 happens. If I tail -f /var/log/maillog on the server, I can usually determine when 6/7 will fail because there is a line or two with: "dovecot: map: Disconnected: logged out message” being shown, even though the Outlook client is still open. After I see that Outlook closed an IMAP session, even though outlook is still running, I can send a message from Outlook and after it appears in my inbox, dovecot panics/hangs immediately Authentication is otherwise working, e.g. test with: /usr/bin/ntlm_auth —username=alice occasionally takes several seconds to respond, but is usually immediate response is always NT_STATUS_OK: Success (0x0) (I welcome tips to make ntlm_auth always respond more quickly!) I have tried adding lines to smb.conf like: win bind cache time = 300 win bind offline login = true No success I have also looked further into the detailed debugging logs and there is: dovecot: auth: Error: Go user=[alice] domain=[OFFICE] workstation=[pc1] len1=24 len2=290 dovecot: auth: error: login for user [OFFICE]\[alice]@[pc1] failed due to [Wrong Password] dovecot: auth: Error: GENSEC login failed: NT_STATUS_LOGON_FAILURE dovecot: auth: winbind(?,x.x.x.x,<XXX>): user not authetnicated: NT_STATUS_LOGON_FAILURE But I am not sure why there would be that error, since earlier IMAP sessions are working just fine with the same exact domain/username and password. It seems to be something about Outlook quickly opening up new simultaneous IMAP sessions with a CONT command, and NTLM authentication somehow fails with one of them, and panics. It always seems to be when sending an email. Like the process of either receiving a new msg in the inbox and/or also posting the just sent message into the Sent Items folder via IMAP (perhaps when it happens simultaneously, as in a message you cc yourself on) is somehow triggering this. Here is more detailed information that can hopefully help track this down.

Dumb question: dovecot include file
by Jerry 29 Mar '16

29 Mar '16

Dovecot has an include file option. What I am not sure of is why those files use both a *.conf and *.conf.ext extension. I assume both types are included by using the !include <FILE>.conf or !include <FILE>.conf.ext syntax. -- Jerry

mailbox prefix
by michael crane 29 Mar '16

29 Mar '16

dovecot version 2.2.13 hello, I try to make a new server just for me after having old one working for ages with Dovecot, Fetchmail, Squirrelmail, Procmail making new one with above plus Postfix using Maildir structure. I am having a bit of trouble understanding exactly what the namespace and prefix are. Is the "private/" prefix an internal thing with Dovecot ? Or is it supposed to be a real directory ? I'm not quite sure how to properly address the INBOX in Procmail, Squirrelmail, Postfix config. for example am I supposed to say inbox is ".private/.INBOX" cheers zemlik

Migrating to dovecot from gmail apps
by Phil Lello 28 Mar '16

28 Mar '16

Hi, I'm considering migrating away from gmail for my (one-man) company, and I'm trying to decide if dovecot is the right option (I'm committed to self-hosting). I'm a developer, so happy to do my own tooling if needed. *Is there currently a good webmail interface to dovecot, or work-in progress?* If not, would a web interface be out-of-scope for dovecot? I want to use SAML for authentication, so a solution that relies on POP/IMAP doesn't meet my needs - unless I add Kerberos into the mix, which is an additional learning curve, and possibly not widely supported. *Is there currently a good web admin interface to dovecot, or work-in-progress?* If not, would a web interface be out-of-scope? Since I prefer using password-protected SSH keys for shell access, and don't want to tie myself to a laptop (and would hate to use vim on a 3G/4G tablet), I'd like to be able to add/remove aliases and play with SIEVE and ACLs through any available browser. *How's the work on sharing messages between folders progressing?* Finally, and I hope you don't mind me asking, are you aware of a good JAVA based alternative to dovecot? I quite like the idea of using lucene indexing on mailboxes, so reducing the number of dependencies has a certain appeal. Best wishes, Phil Lello

Hello, Sorry if I am off topic a little. I am looking for an email host provider that supports dovecot, sieve and manage sieve. Ideally with the roundcube webmail and managesieve plugin Better if it is in Europe or switzerland. I don't mind paying a little. Thanks, André.

Enabling tcpwrappers
by kepa 28 Mar '16

28 Mar '16

Hi all, I would like use Dovecot with tcpwrappers enabled to control remote access using hosts.deny and hosts.allow. A google search gave this response from the listserve, but it is several years ago: http://www.dovecot.org/list/dovecot/2013-April/089455.html Are these instructions for configuring the conf files still valid? Mainly: /etc/dovecot/dovecot.conf login_access_sockets = tcpwrap conf.d/10-master.conf: service tcpwrap { unix_listener login/tcpwrap { group = $default_login_user mode = 0600 user = $default_login_user } } Also: Which version of Dovecot at least is needed to enable tcpwrappers? Does the tcpwrap option need to be enabled during configure and build or is it already (and enabled in any distro binary repositories)? And is it dovecot, imap, or imaps in the hosts.allow/deny file as the service name? Thanks! Kepa

However, I cannot afford that because it took me at least 3 months to setup dovecot correctly with postfix to use virtual users. I don't have the time to spend another 3 months to set it up. The problem lies with auth and I think this is the only issue and it has to be that something is missing either in the configs or a file was deleted or link to it was broken.

Re: IMAP Idle

Hmm. I can't think of why dovecot wouldn't time out. I think maybe the problem is with your webmail system -- it's not detecting when a client connection goes away and releasing all the resources associated with that user. This is not a typical problem though -- most webmail software do not keep persistent IMAP connections open during a session unless they use some IMAP proxy. Are your IMAP connections connected to the webmail server or an IMAP proxy, and is that connection active (despite webmail user disappearing)? Joseph Tam <jtam.home(a)gmail.com>

Need help solving issue

Hi, I am using Dovecot 2.2.18 and have migrated from a 1.x versions. After this migration I had several errors and obsolete errors in logs. I fixed them and after all that I finally was able to run postfix and dovecot again. The problem I have facing right now is that in the mail logs and in the dovecot logs. I am getting auth errors. In mail log the postfix is spitting out: " fatal: no SASL authentication mechanisms" Dovecot is spitting this out "imap-login : Auth process broken (disconnected before auth was ready, waited 0 secs): ,user<>, the shows client ip, my server ip and then the 0 seconds connection etc. Error: auth: environment corrupt; missing value for DOVECOT_" That is what it spits out. I asked for help and many threads.I am using freebsd 10.2. I do use mysql for database. I need someone to explain what the error means and how I can fix it? Thank you for your time!

Since then, I have run dozens of traces to isolate the problem, difficult because there are timing issues involved. I have finally nailed it down. If this is not the proper place to report such bugs or if someone knows that this bug has been fixed, please let me know. As I noted in my earlier post, we have been running Dovecot 2.2.10 with a pair of CentOS 7 boxes with replications for the past year.

After running a pile of traces, I determined that the problem was strangely related to replications. For the purposes of this discussion, I will refer to the two symmetric replicating servers as A and B. Further, let us assume that during "normal" operation, all the emails are delivered to A via SMTP and are replicated to B. Under those assumptions, if the IMAP user connects to A (where the messages were originally delivered), there is no problem, at least no problem I was able to find. The problem I am describing only arises if the IMAP user connects to B. Connecting to B has never presented any other problems that I am aware of. >> > >> >The test for which I have provided the trace starts with a test mailbox containing only 3 unread messages in the INBOX. Moving 1 of the unread messages to Trash is all that is needed to reproduce the problem. Remember this is ONLY a problem if the IMAP sessions do not connect to the server to which the messages were originally delivered. Also, I found that there is a timing window. The critical IMAP commands are: >> > >> > UID STORE xxx +FLAGS.SILENT (\Seen) >> > UID MOVE xxx Trash >> > >> >If you introduce a large enough delay (I arbitrarily chose 5 seconds) between those two commands, there is no problem.

Would be a good idea to try anyway with v2.2.22.rc1 (which seems to be stable enough that I'll make v2.2.22 release soon). > > Anyway, I attempted a few times to reproduce it with your test but wasn't able to. I was out when you were kind enough to reply. To answer your question, we are using Maildir format. The trace I provided was based upon IMAP interactions with Roundcube (though the problem was reproducable with several mail clients). I left in a few more steps to make the trace look less contrived. However, I reduced it further to just a couple of connection sessions. What I found in that exercise that was not apparent to me in my prior posting was that the "STATUS INBOX" command that ultimately reveals the problem (it shows the message reappearing) only becomes "wrong" when it is done in a subsequent session. That is, even if I inject an artificially large delay after the "UID STORE" / "UID MOVE" commands before the "STATUS INBOX" command in the same session, that result is never "wrong". But, as soon as I open a subsequent IMAP session, the "STATUS INBOX" command then shows the problematic results. I have never dug into the Dovecot code base, but I assume this relates to how the session data is cached and how the replications update it. None of this is relevant if the problem has already been fixed, so I will endeavor to set up a couple of test boxes with the current version to verify. The link you provided does look quite hopeful. Thanks so much.

I had much the same situation where a user signed up with a roaming wireless carrier that assigned a new IP to the client whenever it got passed from one access point to another. Good fun when this person took a bus ride through the city, leaving orphaned connections in its wake. The IDLE disconnection timeout is hardwired in the Dovecot code http://wiki.dovecot.org/Timeouts It's set to the RFC minimum of 30min. You'll have to recompile Dovecot to lower this to a non-RFC compliant value. I'm not sure how this this will affect clients, but 30min seems to be overly generous. Joseph Tam <jtam.home(a)gmail.com>

NetApp NFS vs. ZFS and NFS for Maildir
by Alessio Cecchi 26 Mar '16

26 Mar '16

Hi, I'm evaluating to switch from NetApp to a ZFS appliance (like Qsan). Our setup is Dovecot, Maildir for email storage and NFS to share mailboxes (more than 30k users) across POP/IMAP and MX servers. NetApp NFS works fine also under high load but have some limitation for inode numbers per Volume and is expensive (but recently their prices have dropped). ZFS, I read, suggest to create many small Raid Group to increase IOPS, but this configuration (N Raid instead of one RAID-DP like NetApp) is more complex to manage, or not? Someone has experiences with ZFS and NFS(v3) in high load environments? Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

State for dsync not working.
by Simon Pierre Desrosiers 26 Mar '16

26 Mar '16

Hello, Since replication does not seem to work on Mac OSX, I will run doveadm sync by hand every few minutes. In order to improve efficiency, I would like to use state. I have tried a few ways, but I always get the following error doveadm(user): Error: Saved sync state is invalid, falling back to full sync: Invalid base64 data KBtMOd0181bQ/wAAoQsxE90181YBAAAAAQAAAAAAAAAAAAAAAAAAABtI+mg= Here is the code I use to sync : for user in $userlist ; do doveadm sync -u $user -s "/Users/_dovecot/.bin/syncStates/syncstate$user" tcp:xxx.xxx.xxx.xxx > "/Users/_dovecot/.bin/syncStates/syncstate$user" done Any idea on how I can correct the encoding error ? Thank you

IMAP Idle
by Joy 25 Mar '16

25 Mar '16

Hi guys, We have implement imap idle in web mail built by us to have push mail feature. IMAP idle working perfectly with browser notification and we are happy with it but having one issue with users who close the browser directly and never logout in that case there are number of idle connection which are not in use and users are unable to login once IP wise connection limit is reached. Dovecot is not closing connection which are not in use, is there any setting available which can help me to resolve this issue.

Trouble handling encrypted passwords
by Dan Wilson 25 Mar '16

25 Mar '16

I am running into trouble when I try to use encrypted passwords. I set my dovecot 2.2.10-5 installation back to plain text passwords and was then able to login and retrieve emails. When I set the default_pass_scheme to MD5-CRYPT in my sql config file, and store an MD5-CRYPT password in the sql database, I invariably get password mismatch errors on login: Mar 24 19:40:30 server1 dovecot: auth: Debug: client in: AUTH#0113#011PLAIN#011service=imap#011secured#011session=25HcztQuwQBHCDBi#011lip=xx.x.xx.xxx#011rip=71.8.48.98#011lport=993#011rport=60609#011resp=<hidden> Mar 24 19:40:34 server1 dovecot: auth-worker(9443): Debug: sql(test1(a)xxxxxx.com,xx.x.xx.xx): query: SELECT email as user, password FROM virtual_users WHERE email='test1(a)xxxxxx.com'; Mar 24 19:40:34 server1 dovecot: auth-worker(9443): sql(test1(a)xxxxxx,xx.x.xx.xx): Password mismatch Mar 24 19:40:36 server1 dovecot: auth: Debug: client passdb out: FAIL#0113#011user=test1(a)xxxxxx.com The password in the database was created using doveadm pw command and is stored as: {MD5-CRYPT}$1$5QAeG70c$dP8y7XJVd.VxZBF/DvcAa0 I tried removing the {MD5-CRYPT} from the password string, but that didn't help.

Replication issues master <-> master nfs backend
by William L. Thomson Jr. 24 Mar '16

24 Mar '16

I keep having some replication issues and not sure what can be done to resolve or correct. It does not seem to happen all the time, though for the last ~30 or so minutes and many messages seems to be happening consistent for me. I have 2 mail servers, basically clones, and thus master master replication. Most of the time things work fine. But many times an email or several will arrive on one, and never replicate to the other. I am not as concerned on the never replicating, as I am that the user never gets notified. Mail arrives on say server 1, users are checking mail on server 2, and they never see the email on server 2. This is not always the case, but its happening enough daily. I then log into one and run sync manually. Which usually syncs the mail on both servers, and then it arrives in the inbox. Here is an example, mail is on mail2, but not mail1. I am checking email on mail1 so I am not seeing the 1 email. Mail1 /home/wlt-ml/.maildir/new: total 0 Mail2 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673024.7643.mail2 Then I manually log into mail2 and run this command, though usually I can run it from either side, and just change the name to the other server. doveadm sync -u "*" remote:mail1 And then I end up with the missing email on mail1, and it arrives in my email client shortly there after Mail1 /home/wlt-ml/.maildir/new: total 12 -rw------- 1 wlt-ml site1 8502 Mar 22 14:57 1458673051.M838843P26735.mail1,S=8502,W=8678:2,T I have no idea why it does this. It seems to happen when when a full sync has taken place per doveadm replicator status wlt-ml. There does not seem to be any settings to force a full vs fast sync more often. No clue if this is even a full vs fast issue or other. I think it tends to happen more when people stay connected to the imap server. I had a theory that closing the email client and opening it again will get dovecot to sync. I believe this is still the case, but not able to confirm 100%. Also users are reporting closing Thunderbird. I can see them logging out and back in in the logs, but email does not replicate or show till I run doveadm sync manually. Tempted to have cron invoke that on the regular, but seems very hackish and likely will have its own issues doing that. Since its not the right way or how things were designed. Not sure if this is a bug or what. Hopefully miss-configuration on my end. Open to any feedback, advice, etc. I can provide replicator configuration but its pretty straight forward and mostly copy/paste from the replication page. Replication works, just seems it is not triggered to replicate at times or something. dovecot --version 2.2.22 (fe789d2) -- William L.

My imap_logout_format is: imap_logout_format = in=%i out=%o session=<%{session}> Thanks -- Alessio Cecchi Postmaster @ http://www.qboxmail.it https://www.linkedin.com/in/alessice

Allowing for multiple recipient_delimiter characters?
by Aaron Lindsay 23 Mar '16

23 Mar '16

Postfix allows the recipient_delimiter configuration parameter to contain multiple characters, splitting on the first such character it encounters. For example, if using 'recipient_delimiter=+-' both aaron+foo(a)example.com and aaron-bar(a)example.com would be delivered to aaron(a)example.com. Is anyone opposed to changing dovecot's handling of recipient_delimiter so that it's the same as that of postfix? If not, I am willing to rebase/merge/address review comments on Lennart Weller's patch[1] to get this functionality upstream. While I think aligning with postfix' behaviour would be convenient for those of us who run a server using both dovecot and postfix, would this break any other common use cases I'm not aware of? Thanks! -Aaron [1] - http://dovecot.org/pipermail/dovecot/2015-February/099660.html (I've talked with Lennart off-list, and he's OK with me working to get his patch merged, as long as I attribute his work to him, but doesn't have the time to work on it himself right now)
