Moving Alternate Storage to another disk.
by bOnK 03 Jan '19

03 Jan '19

Hello, Dovecot 2.3.4_3 on FreeBSD 11.2. I am using mdbox Alternate Storage since about two years without any problems. However, the disk containing this storage is almost full and I have to move this data to another disk, probably zpool. Would it be okay to do the following? 1) Shut down dovecot (and mail server) so no new mail comes in. 2) Copy/move all files in ALT location to new disk, using shell commands like cp/mv/cpdup. 3) Change the path to ALT in dovecot-conf mail_location. 4) Change the 'dbox-alt-root' soft-links in each users main (INBOX) directory to point to this new location. 5) Start up dovecot and mail server. Am I missing something or maybe there is a better way? -- Thanks, and have a nice new year. bOnK

Sieve script unable to file into public folder after dovecot upgrade to version 2.3.4
by Andreas Oster 03 Jan '19

03 Jan '19

Hi all, Wishing you and your families a Happy New Year 2019. I am currently struggling with an odd sieve issue after upgrading dovecot from 2.2.32 to the latest 2.3.4 version. OS is Ubuntu 18.04. For one of our users I have a sieve rule in place which should copy (keep + fileinto) incoming mails from the INBOX to a public namespace folder. Unfortunately this does not work anymore. In the sieve log file of the user I get error messages like this: sieve: info: started log at Jan 02 12:41:31. error: msgid=<dc6bdcb2-7efb-0f0a-3a6d-c1133233c11f(a)novanetwork.de>: failed to store into mailbox 'Public/Verteiler': Permission denied. This is the content of the sieve script : require ["fileinto"]; keep; fileinto "Public/Verteiler"; stop; At first I thought it might be caused by a faulty IMAP ACL but this does not seem to be the case. When I do a manual copy in Thunderbird from the INBOX to this public folder there are no problems at all. Does anybody have an idea what could be the cause of the issue ? Thank you very much for your kind help. Best regards Andreas

dovecot-uidlist path
by Christos Chatzaras 02 Jan '19

When I use this: mail_location = maildir:/home/mail/%d/%n the dovecot-uidlist file is located in: /home/mail/example.com/user/dovecot-uidlist But when I change it to: mail_location = maildir:/home/mail/%d/%n:CONTROL=/var/mail/%d/%n then it's stored in: /var/mail/example.com/user/.INBOX/dovecot-uidlist Any idea why is not stored in: /var/mail/example.com/user/dovecot-uidlist ?

Error with virtual index "Broken mailbox_count header"
by Tobias Kirchhofer 02 Jan '19

02 Jan '19

Hi, we experience trouble with one of our virtual mailboxes. dovecot-virtual: ` * -INBOX/Trash -INBOX/Spam all ` Error log: ```Error: virtual index /var/vmail/mailboxes/kirchhofer.net/tobias/virtual/all: Broken mailbox_count header``` This happens only with the filter form above. All other virtual mailboxes works fine. Jakobus Schürz experienced something similar: https://www.dovecot.org/list/dovecot/2018-January/110656.html We do not have the panic message. Is this probably something on our side or is this Dovecot? ``` namespace virtual { prefix = Virtual/ separator = / location = virtual:~/virtual } -- collect(a)shift.agency

I had this previous installation working, with LD_LIBRARY_PATH configured, on solaris 10 u8 since 2014. During this relativelly calm period I did a LiveUpgrade to latest solaris 10 ( u11 ) and the only application that stopped working is dovecot. This mean that ( obviously ) solaris changed something on security. No binary is setuid or setgid in dovecot dir: ls -l /usr/local/dovecot/sbin/dovecot -rwxr-xr-x 1 root root 259452 Dec 29 14:59 /usr/local/dovecot/sbin/dovecot root@puma find . -perm 4000 root@puma find . -perm 2000 root@puma find . -perm 1000 but yes, I agree that eventually the SRL stuffs could make them job. Probably is not tied to the setuid/setgid but with the fork of a binary from inside another one with the LD_LIBRARY_PATH in use. Thus the option is ( could be ) to use the R[UN]PATH feature or the wrapper with the new LD_LIBRARY_PATH ( as I'm doing now altough less secure ) or recompile with the -R option passed to linker, as suggested by James ( and verified to be working at least with the "dump" ).

Several problems on Solaris10
by Pierluigi Frullani 01 Jan '19

01 Jan '19

Hi all, I've just upgraded my old Solaris 10 update 8 to Solaris 10 update 11 with the latest patches, but after the reboot with the new update I'm having a lot of problems with dovecot. My version is 2.2.13 ( it was the last one, at the time of the first server setup ). I have seen that ( it seems ) the new solaris don't honour the LD_LIBRARY_PATH. The first error was a relocation error: relocation error: file /usr/local/dovecot/lib/dovecot/libdovecot-login.so.0: symbol EVP_PKEY_get1_EC_KEY: referenced symbol not found Just to bypass this phase I have linked the openssl-1.0.1e in /usr/local/lib ( libssl and libcrypto ) but then I got a new relocation error: imap: Error: dlopen(/usr/local/dovecot/lib/dovecot/lib20_fts_plugin.so) failed: ld.so.1: imap: fatal: relocation error: file /usr/local/dovecot/lib/dovecot/lib20_fts_plugin.so: symbol http_url_parse: referenced symbol not found Did someone has some idea on how to bypass those troubles ? Thanks in advance Pierluigi

BUG mailboxaliases, does not take into account namespaces

Does not honour namespaces. Should at least get the namespace location and link to that location and not just created a folder and link to it in the main/top? Namespace.

BUG mailboxaliases plugin not working with subfolders
by Marc Roos 30 Dec '18

30 Dec '18

The mailboxalias plugin is not working when subfolders are created, rendering its use quite useless. It should work of course something like this. (then I would be able eg. to put my archive mailboxes on different storage, by just creating one symlink on archive (get it??;)) If there is a new mailbox created And in its path there is a folder/path configured in aliases plugin Get the original folder location of that symlink Create a new file with the original name + new subfolder name, in the same location as the parent And then create a symlink to that created file with Thus not this mailbox_alias_old8 = Archive mailbox_alias_new8 = Archived messages -rw------- 1 xxx xxx 0 Dec 30 15:36 .Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages -> .Archive -rw------- 1 xxx xxx 0 Dec 30 15:40 .Archived messages.am-test But this: -rw------- 1 xxx xxx 0 Dec 30 15:36 .Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages -> .Archive -rw------- 1 xxx xxx 0 Dec 30 15:40 .Archive.am-test lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages.am-test -> .Archive.am-test And then if you fix this, you might aswell take this into account. Thus in case I already have a symlink on .Archive -rw------- 1 xxx xxx 0 Dec 30 15:36 .Archive -> /home/mail-archive/userx/.Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages -> /home/mail-archive/userx/.Archive lrwxrwxrwx 1 xxx xxx 8 Dec 30 15:36 .Archived messages.am-test -> /home/mail-archive/userx/.Archive.am-test Then your mailboxaliases plugin starts to make sense a bit, now it is not consistent in its naming and is only creating a mess.

Archive namespace accepting messages to the main folder
by Marc Roos 29 Dec '18

29 Dec '18

I am struggling with an archive namespace. I am not sure if this is can solved. But if you right click in apple mail on a message and choose archive. It wants to move the message to the folder Archive folder (marked in the attached). If I set inbox=yes it is possible to move the mail in this folder, but then I get other problems (two namespaces with inbox=yes). When I leave it inbox=no, I get a complaint of apple mail that the mailbox is not selectable (attachment) namespace { type = private separator = / prefix = Archive/ location = mbox:/home/mail-archive/%u/Archive/:CONTROL=/home/mail-archive/%u/Archiv e/control:INDEX=/home/mail-archive/%u/Archive/index:LAYOUT=maildir++ inbox = no hidden = no list = yes subscriptions = yes } PS.

Hello, I run Dovecot 2.3.2.1 and I keep separate index / control files: mail_location = maildir:~/Maildir:INDEX=/liveindexes/indexes/%d/%n:CONTROL=/liveindexes/control/%d/%n When I try to set an ACL on a folder, I get this error: Dec 26 17:35:56 imap2 dovecot: imap(user(a)domain.com): Error: file_dotlock_open(/home/vpopmail/domains/domain.com/user/Maildir/.Test/dove… failed: Resource temporarily unavailable Dec 26 17:35:56 imap2 dovecot: Error: imap(user(a)domain.com): Mailbox Test: Failed to set ACL Is it normal for it to try opening the dotlock in the Maildir ?

Problem with different certificates
by Andreas Meyer 27 Dec '18

27 Dec '18

Hello! Dovecot manages different domains. Today I renewed the certifiactes from letsencrypt and since that time, dovecot does not recognized the certs for different domains anymore: This is part of my config: ssl = yes ssl_cert = < /etc/letsencrypt/live/bitcorner.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/bitcorner.de/privkey.pem local 37.120.166.21 { # instead of IP you can also use hostname, which will be resolved protocol imap { ssl_cert = < /etc/letsencrypt/live/bitcorner.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/bitcorner.de/privkey.pem } } local 46.38.231.143 { protocol imap { ssl_cert = < /etc/letsencrypt/live/nimmini.de/fullchain.pem ssl_key = < /etc/letsencrypt/live/nimmini.de/privkey.pem } } This worked for years and I don't know what's wrong now. It seems dovecot just takes the default certs into account and ignores the certs defined with "local" completly. Any help appreciated. Kind regards Andreas -- PGP-Fingerprint: F004 8EEE 5E54 F2EA 566E B939 22E5 85DD AA14 AC0A

Re: Errors with missing links to files when using Single Instance Storage and zlib (Dovecot 2.3.4)
by Daniel Schütze 27 Dec '18

27 Dec '18

Having had a week with the system I'm now inclined to believe that the issues I've seen are not necessarily related to SIS and zlib but may be due to replication instead. After experiencing these issues and looking at historical mailing list posts I wrote a basic script (as was suggested as a possible diagnostic approach for SIS before SIS was even implemented!) which pulled all the mail from a user doveadm fetch -u username body all > /dev/null 2>error.log This generated errors in error.log for every e-mail with a problem. From that and some use of sed,uniq,cut and ln I was able to (re)create the missing links. Unfortunately the error generated was only the first missing link for all the links expected for an e-mail. So my script had to be run multiple times per user until no more errors were reported. This wasn't all that onerous given I was basically running on a test box before mass migrating my users. A better approach would have been to scan the mdbox files for all links expected and check the existence of them all. Having (re)created all missing links I've not had a single instance of a link being missing after a week of delivery of mail (where the errors were regular before this procedure). I have also since looked at how replication handles links. What I hadn't expected was that the links created on the server pair are not the same. Although I had two servers which started in the same state (one a clone of the other) after a month or so of replication they had diverged to the state where if I sent a test message to the one server I could see the file name of the link created to the has was not the same on both servers (although obviously the hash itself was the same name and content wise). This leads me to believe the errors I saw where most likely down to my expecting the two servers in the pair to have identical SIS attachment directories/hardlinks to hashes and the way I handled my migration. Coming from a database mail server were replication master/slave means the backend should be absolutely identical if all is working I may simply have gotten the wrong idea of dovecot replication. With my 2.3.1 and 2.3.4 replication pair there were a lot of the tcp errors which the changelog for Dovecot stated had been fixed post 2.3.1; mainly the connection timing out after 10 minutes. Looking at the code for replication (which I'm not going to claim I've fully go to grips with) it looks like the name of a hardlink is made up of essentially [hash]-[identifier including mailbox GUID]. It must be the case then that the [identifier including mailbox GUID] can diverge between server pairs, at least with 2.3.1 as a version involved.

I am running Dovecot 2.3.4 on FreeBSD11.2 and I did not see this error on Dovecot 2.3.1 FreeBSD 10.4. Both installs had the same configuration for Dovecot. Both installs were made from source code and not packages (as the need for the non standard fts and mysql options). During my testing I had the 2.3.1 install receive mail and replicate to the 2.3.4 and that was working fine (except for tcp connection issues which I saw was fixed in the changelog). Unfortunately having gone into testing with real account and mail being sent to the 2.3.4 install I'm seeing the above errors. My clients are using Thunderbird on desktops and Roundcube for webmail. My users report they can see the e-mails fine in their webmail (Roundcube) and only Thunderbird is giving issues. I admit I don't know how this can be the case as both systems use the same account details. In everycase so far there is a file in the hashes directory I have hand crafted the missing file (i.e. link) using ln and this restores access in Thunderbird. Clearly this is an big issue for my install and I'd appreciate any help! At the moment it looks like my course will be to try and script creation (recreation?) of the links from the error logs (I've seen people talking about this online) but that isn't really what I'm after.

Migration to 2.3.36 using replication
by Thomas Durand 26 Dec '18

26 Dec '18

Hello, I have to migrate my dovecot box to a new one. I would like to know if it’s possible to do this migration with the replication process. My plan is to activate replication between 2.2.10 server and the 2.3.4 new server. Then I will update the DNS to redirect the name to new box. Users will then connect either on the new or the old box depending on the dns upgrade. Does anyone have already experienced such process ? Is there any incompatibility issue ? Thanks. Thomas

Heads-up regarding non-replication of Sieve scripts?
by Markus Ueberall 25 Dec '18

25 Dec '18

Dear all, A couple of months ago, it has been mentioned that multiple users experienced a problem regarding the synchronisation of Sieve scripts by means of "dsync" (whereas e-mails were replicated just fine between servers) [1][2] for Dovecot v2.3.x; the same problem apparently occurred with early versions from the v2.2 branch some three years ago but has been marked/confirmed as fixed back then [3]. Since I'm currently using the 2.2.33.2[-1ubuntu3] packages from the Dovecot community software repository and would like to upgrade to v2.3.x at one point, I'm very interested in hearing whether the above problems have been fixed (if so, how?) since I do not want to semi-manually synchronise the Sieve scripts between two mail servers in active/active mode on my own. Thanks in advance for a heads-up / Kind regards, Markus [1] https://www.dovecot.org/pipermail/dovecot/2018-October/113244.html [2] https://www.dovecot.org/pipermail/dovecot/2018-August/112548.html [3] https://www.dovecot.org/pipermail/dovecot/2015-February/099658.html

Password expiration: how to trigger it?
by Cédric Jeanneret 21 Dec '18

21 Dec '18

Dear Dovecot Team, I'm in the (long) process of migrating my whole email infrastructure. Of course, dovecot is in the place, and is working just fine. Still, I have an issue: password expiration. I'm now using FreeIPA backend for the user authentication, and it includes the capacity to expire passwords. Basically, it's an LDAP with fancy things, among them a field named krbPasswordExpiration (yes, that's kerberos). In order to make things simple, I'd rather NOT force my users to set up a kerberos/gssapi/whatever on their personal computer (most of them will just have blank gaze if I start talking about that). Is there a way to make Dovecot use that field? It's apparently a simple date in %Y%M%D%H%m%sZ format, so a pretty neat thing to test. If there's some support for that in Dovecot, that is. If not, as a last resort, I can configure the freeIPA to deactivate the user if the password is expired, and this should push another field in the user description. Would that be a possibility for Dovecot, in case it can't use the datetime field as is? Thank you for your support! Cheers, C.

outlook idiocy - IMAP folders with /
by Wojciech Puchar 20 Dec '18

20 Dec '18

user attempts to create folders with / dovecot naturally cannot create it so it returns error but outlook of course "create" it and keep data in local store only. data is lost when you remove local store .pst file. The question is - can dovecot be configured so it will automatically replace slash in name with something else?

SIS feature request
by Daniel Miller 20 Dec '18

20 Dec '18

I tried SIS a couple years ago - I was very excited with the resulting decrease in storage requirements but the undiagnosed intermittent issues became too significant to ignore so I switched away. Recently I was thinking about it again. The primary issue with SIS seemed to be links would be deleted even though the source attachment files and related mails still existed. It was possible to either manually re-build the links or have a script scan the mail error log and perform such. I haven't looked at the code - but a thought for a possible "temporary" fix: 1. Whatever function in dbox code that performs the deletion of links - prior to actually deleting call a new function that will verify if any mails exist that reference it. A new function, without modifying existing code, may catch something the existing functions don't - and if it logs the fact that it was called and found something...perhaps we can find the flaw in the original algorithm. Just a thought. 2. In the mail retrieval function, if the attachment link doesn't exist - perform the relevant scan through the attachment database and if found re-create the link automatically. This should log an error but indicate the recovery. -- Daniel

Hi list! For some reason I need to use a really weak server key (256 bit) with dovecot for imaps access. Is this possible? I tried but getting this error: dovecot: imap-login: Error: SSL: Stacked error: error:04075070:rsa routines:RSA_sign:digest too big for rsa key This is on an Ubuntu 14.04 on x64. Thank you! Stavros

High Load average on NFS Spool - v.2.1.15 & 2.2.13
by Albert E. Whale, CEH CHS CISA CISSP 19 Dec '18

I have two servers pointing to an NFS mounted mail spool with dovecot. Since I recently switched from using Dovecot v1.X, I have been experiencing high CPU use with the two Dovecot servers. I am not certain why they are not well behaved. Here is the configuration information. This configuration is currently running at a load average of 17. /usr/sbin/dovecot -n # 2.1.15: /etc/dovecot/dovecot.conf # OS: Linux 3.10.54-server-2.mga3 i686 Mageia 3 base_dir = /var/run/dovecot/ disable_plaintext_auth = no lock_method = dotlock login_greeting = SpamZapper Email ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_debug = yes mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail mbox_lock_timeout = 15 mins mmap_disable = yes passdb { driver = pam } protocols = imap pop3 service anvil { client_limit = 203 process_limit = 1 } service auth { user = root } service imap-login { chroot = login client_limit = 10 user = dovecot vsz_limit = 256 M } service pop3-login { chroot = login client_limit = 20 user = dovecot } ssl = no syslog_facility = local2 userdb { driver = passwd } verbose_proctitle = yes protocol pop3 { mail_max_userip_connections = 20 pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_uidl_format = %08Xv%08Xu } protocol lda { postmaster_address = postmaster(a)example.com } protocol imap { mail_max_userip_connections = 10 } And the other server which is currently running with a load average of 10. dovecot -n # 2.2.13: /etc/dovecot/dovecot.conf doveconf: Warning: service anvil { client_limit=100 } is lower than required under max. load (303) # OS: Linux 4.1.15-server-2.mga5 x86_64 Mageia 4 base_dir = /var/run/dovecot/ disable_plaintext_auth = no listen = * lock_method = dotlock login_greeting = SpamZapper Email ready. login_log_format_elements = user=<%u> method=%m rip=%r lip=%l %c mail_fsync = always mail_location = maildir:~/Maildir mail_nfs_index = yes mail_nfs_storage = yes mail_privileged_group = mail mmap_disable = yes passdb { driver = pam } protocols = imap pop3 service anvil { client_limit = 100 process_limit = 1 } service auth { user = root } service imap-login { chroot = login client_limit = 48 user = dovecot vsz_limit = 256 M } service pop3-login { chroot = login client_limit = 50 user = dovecot } ssl = no syslog_facility = local2 userdb { driver = passwd } verbose_proctitle = yes protocol pop3 { mail_max_userip_connections = 50 pop3_logout_format = top=%t/%p, retr=%r/%b, del=%d/%m, size=%s pop3_uidl_format = %08Xv%08Xu } protocol lda { postmaster_address = postmaster(a)example.com } protocol imap { mail_max_userip_connections = 40 } Can you please offer a suggestion on what is happening?

Re: How to configure Dovecot to disable NIST's curves and still rertain EECDH?
by Kurt Fitzner 19 Dec '18

19 Dec '18

My opinion is that security by RFC is not security, it's mommy medicine. Standards have had a terrible time keeping up with security realities. NITS's curves leak side channel information all over the place. I don't have details on what implementations are set to calculate the NIST curves in constant time, and that's not an easy feat to do anyway so I don't want to depend on implementations that say they are actually doing it the right way. Frankly I can't be bothered to keep up with that. There are better curves TODAY, so yes I intend to use them if I can find a way. Otherwise, I'll just keep EECDH disabled. I have EDH now, and I've not yet run into a client that doesn't support it. I want EECDH, but I won't use it without safe curves. I'm confident that EECDH with safe curves and a second choice of EDH will support any clients that are worth using. OpenSSL supports X25519, and that is half the battle. Is there a way to change the curve selection in Dovecot?

How to configure Dovecot to disable NIST's curves and still rertain EECDH?
by Kurt Fitzner 19 Dec '18

19 Dec '18

I am interested in configuring Dovecot's TLS so as to retain forward secrecy, but eliminate all of NIST's elliptic curves. Besides being subject to side channel attacks [1], in some quarters there is a general distrust of NIST's curves and any of their other cryptographic primitives after the Dual EC DRBG debacle. >From what I can tell, the following will prevent the use of NIST's curves (along with other dangerous primitives) in Dovecot, but this is accomplished by simply disabling EECDH entirely. ssl_cipher_list = HIGH:!DSS:!EECDH:!ECDH:!SHA1:!aNULL:!eNULL:@STRENGTH This should still retain forward secrecy through the use of EDH, but this doesn't leave much in the way of allowable algorithms on my server: $ openssl ciphers -V 'HIGH:!DSS:!EECDH:!ECDH:!SHA1:!aNULL:!eNULL:@STRENGTH' 0x00,0x9F - DHE-RSA-AES256-GCM-SHA384 TLSv1.2 Kx=DH Au=RSA Enc=AESGCM(256) Mac=AEAD 0x00,0x6B - DHE-RSA-AES256-SHA256 TLSv1.2 Kx=DH Au=RSA Enc=AES(256) Mac=SHA256 0x00,0x9D - AES256-GCM-SHA384 TLSv1.2 Kx=RSA Au=RSA Enc=AESGCM(256) Mac=AEAD 0x00,0x3D - AES256-SHA256 TLSv1.2 Kx=RSA Au=RSA Enc=AES(256) Mac=SHA256 0x00,0x9E - DHE-RSA-AES128-GCM-SHA256 TLSv1.2 Kx=DH Au=RSA Enc=AESGCM(128) Mac=AEAD 0x00,0x67 - DHE-RSA-AES128-SHA256 TLSv1.2 Kx=DH Au=RSA Enc=AES(128) Mac=SHA256 0x00,0x9C - AES128-GCM-SHA256 TLSv1.2 Kx=RSA Au=RSA Enc=AESGCM(128) Mac=AEAD 0x00,0x3C - AES128-SHA256 TLSv1.2 Kx=RSA Au=RSA Enc=AES(128) Mac=SHA256 Is there a better way to do this? Is there a way to disable only the suspect NIST curves and still retain EECDH but with side-channel safe curves like X25519?

Errors with missing links to files when using Single Instance Storage and zlib (Dovecot 2.3.4)
by Daniel Schütze 18 Dec '18

18 Dec '18

I'm running Dovecot 2.3.4 with Single Instance Storage (SIS) and zlib and I am frequently seeing errors where files are missing in the attachments directory even though the zipped file in the hash directory is actually there. This appears not to have been an issue in Dovecot 2.3.1 Requested output of the server below. The error looks like this in the log Dec 18 08:58:58 dovecot01 dovecot: imap(username)<3692><RKnPGEh9fC3AqAAB>: Error: Mailbox INBOX/FOLDER: UID=41: read(attachments-connector(zlib(/usr/home/vmail/mail/username//mdbox/storage/m.411))) failed: read(/usr/home/vmail/attachments/91/08/91085773a0774909207852b8f9c98dbe22fe5a31-e88ba0276aae135cd2050000d09efc50[base64:19 b/l]) failed: open(/usr/home/vmail/attachments/91/08/91085773a0774909207852b8f9c98dbe22fe5a31-e88ba0276aae135cd2050000d09efc50) failed: No such file or directory (FETCH BODY[]) I'm also seeing errors when replication fails dovecot: dsync-local(username)<bzg3MqjhGFxmFwAAzRvpBw>: Error: dsync(servername): read(attachments-connector(zlib(/usr/home/vmail/mail/username//mdbox/storage/m.413))) failed: read(/usr/home/vmail/attachments/45/42/4542dcf385f6b4a4dc8752b96db1d7ad8a8023d5-ac735007f6bd135c93440100cd1be907[base64:19 b/l]) failed: open(/usr/home/vmail/attachments/45/42/4542dcf385f6b4a4dc8752b96db1d7ad8a8023d5-ac735007f6bd135c93440100cd1be907) failed: No such file or directory (last sent=mail, last recv=mail (EOL)) It is not the case that every replication fail has a corresponding imap access fail. I am running Dovecot 2.3.4 on FreeBSD11.2 and I did not see this error on Dovecot 2.3.1 FreeBSD 10.4. Both installs had the same configuration for Dovecot. Both installs were made from source code and not packages (as the need for the non standard fts and mysql options). During my testing I had the 2.3.1 install receive mail and replicate to the 2.3.4 and that was working fine (except for tcp connection issues which I saw was fixed in the changelog). Unfortunately having gone into testing with real account and mail being sent to the 2.3.4 install I'm seeing the above errors. My clients are using Thunderbird on desktops and Roundcube for webmail. My users report they can see the e-mails fine in their webmail (Roundcube) and only Thunderbird is giving issues. I admit I don't know how this can be the case as both systems use the same account details. In everycase so far there is a file in the hashes directory I have hand crafted the missing file (i.e. link) using ln and this restores access in Thunderbird. Clearly this is an big issue for my install and I'd appreciate any help! At the moment it looks like my course will be to try and script creation (recreation?) of the links from the error logs (I've seen people talking about this online) but that isn't really what I'm after.
