custom userdb server, Exim, and proxying
by Felipe Gasper 08 Oct '20

08 Oct '20

Hi all, We have Exim using Dovecot for authentication. Dovecot, in turn, consults a custom internal server that answers Dovecot’s userdb queries. When IMAP connections arrive, for some users we want to forward those connections--without authentication--to an external IMAP server. For these users, we return “proxy_maybe” and “nopassword” in the authn response from our userdb server. This tells Dovecot to proxy the connection to a new server without trying to authenticate. Exim, though, doesn’t grok “proxy_maybe”, so it just sees “nopassword”. In response, it just skips SMTP authentication entirely. We could address this if our custom service could know whether the authn is for Exim or not. Exim does send a “service=smtp” in its request to /var/run/dovecot/auth-client, but thus far I don’t see that that’s being passed on to the userdb server. Is there any way I can configure Dovecot so that our userdb server can detect when it’s Exim doing the authentication? Alternatively we could just authenticate on the proxy (i.e., stop sending “nopassword”), but that will entail a new requirements for passwords to be in sync; ideally we’d like to avoid that. Any insight from this group would be much appreciated. Thank you! cheers, -Felipe Gasper

replication flag default setting?
by Norman King 08 Oct '20

08 Oct '20

Hello. I'm playing with dovecot replication. I have a working replication config on a test server and would like to copy that to production but i don't know what's going to happen with existing accounts. Will they automatically start replicating without any further input from me? Is there a flag on the account somewhere that can tell me what the replication status is? Any thoughts on this would be appreciated. dovecot version 2.3.7.2 -- regards Norman King Compass Foundation sysadmin/tech support Phone, 856-974-5335 ext 221 support(a)compassfoundation.io <mailto:support@compassfoundation.io> Website <https://compassfoundation.io>

dovecot 2.3.11.3 namespace/ACL shared folder not accessible in sharing-user's Mail folder tree? have a working config?

I'm running dovecot --version 2.3.11.3 (502c39af9) I'm setting up folder sharing. Following https://wiki.dovecot.org/SharedMailboxes/Shared I've configured a folder to be shared, but it's not seen/accessible in the target user's Mail folder tree.

Version controlled (git) Maildir generated by Dovecot
by Adam 07 Oct '20

07 Oct '20

Hi Everybody, I'd like to start archiving e-mails by moving them to a server with running Dovecot. I installed "dovecot-core" and "dovecot-imapd" (version 2.3.4.1) on Debian 10. One of a few configurations I made is to use Maildir: # grep '^mail_location = ' /etc/dovecot/conf.d/10-mail.conf mail_location = maildir:~/Maildir I successfully moved some e-mails (at this moment it's just a test) to subfolders that describe a year of the backup. I'd like to start using git on the whole Maildir. After going through the Maildir directory and subdirectories I realized that Dovecot saves some extra files that I might not need to backup (version control). Based on my understanding and after reading https://wiki.dovecot.org/IndexFiles I believe that the only files I need to archive are files in "cur/" directory and these files should start with Unix time. So I decided to write a ".gitignore" whitelist that will include only files in "cur/" that start with a number: # cat .gitignore ----------------------------------- !.gitignore !*/ !/Maildir/cur/[0-9]* !/Maildir/*/cur/[0-9]* ----------------------------------- and it's working: # git add . --dry-run ----------------------------------- add '.gitignore' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M110302P17113.mail1,S=8066,W=8276:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M134554P17113.mail1,S=8024,W=8234:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M157569P17113.mail1,S=8005,W=8215:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M180965P17113.mail1,S=8021,W=8231:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M205518P17113.mail1,S=8017,W=8227:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M355896P17113.mail1,S=8042,W=8252:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M52133P17113.mail1,S=8053,W=8263:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M555847P17113.mail1,S=8029,W=8239:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M581502P17113.mail1,S=8047,W=8257:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M606379P17113.mail1,S=8044,W=8254:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M628850P17113.mail1,S=8036,W=8246:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M657431P17113.mail1,S=8069,W=8279:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M681265P17113.mail1,S=8039,W=8249:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M706585P17113.mail1,S=8073,W=8283:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M730046P17113.mail1,S=8059,W=8269:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M753487P17113.mail1,S=8034,W=8244:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M776202P17113.mail1,S=8019,W=8229:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M799238P17113.mail1,S=8085,W=8295:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M822106P17113.mail1,S=8081,W=8291:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M844397P17113.mail1,S=8102,W=8312:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M867952P17113.mail1,S=7964,W=8174:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M889882P17113.mail1,S=7992,W=8202:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M912429P17113.mail1,S=8005,W=8215:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M935326P17113.mail1,S=8027,W=8237:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M959570P17113.mail1,S=8037,W=8247:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986418.M987388P17113.mail1,S=8018,W=8228:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M112704P17113.mail1,S=8044,W=8254:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M13262P17113.mail1,S=8025,W=8235:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M321294P17113.mail1,S=8012,W=8222:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M347297P17113.mail1,S=8014,W=8224:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M36960P17113.mail1,S=8037,W=8247:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M371029P17113.mail1,S=8005,W=8215:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M395270P17113.mail1,S=8024,W=8234:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M418277P17113.mail1,S=8046,W=8256:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M441021P17113.mail1,S=8047,W=8257:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M466329P17113.mail1,S=8025,W=8235:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M491134P17113.mail1,S=8038,W=8248:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M515650P17113.mail1,S=8046,W=8256:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M539950P17113.mail1,S=8017,W=8227:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M563073P17113.mail1,S=7983,W=8193:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M587009P17113.mail1,S=7963,W=8173:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M611652P17113.mail1,S=7994,W=8204:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M65180P17113.mail1,S=8015,W=8225:2,S' add 'Maildir/.INBOX.years.2020.family/cur/1601986419.M90376P17113.mail1,S=8036,W=8246:2,S' ----------------------------------- Would you be so kind and confirm that this is all I need to archive and that Dovecot will/can re-create all files ignored by git?

RE: How to Modify Message and add more Attachments
by Marc Roos 07 Oct '20

07 Oct '20

I have clients that process personal data and they even need to have 'special' processing agreements with companies like wetransfer and outlook.com. I had to sign also such agreement and prepare a vm for hot/cold data encryption for processing personal data. If someone leaves a voice mail message, he does not expect that this is going to be send to a third party. I think this expectation causes the gdpr 'by default' highest privacy/security of personal data protection to be applicable. Lots of companies are being fined currently for breaching gdpr, small, large, international even nation governmental organisations. Better check this. -----Original Message----- Subject: RE: How to Modify Message and add more Attachments Can you elaborate on the concern? -----Original Message----- From: Marc Roos <M.Roos(a)f1-outsourcing.eu> Sent: Tuesday, October 6, 2020 4:17 PM To: dovecot <dovecot(a)dovecot.org>; Mrinal Sharma <msharma(a)smithmicro.com> Subject: RE: How to Modify Message and add more Attachments CAUTION - EXTERNAL EMAIL This email originated from outside of Smith Micro Software.

Strange errors after updating to 2.3.11.3
by Samuel Williams 06 Oct '20

06 Oct '20

Hello, After a recent update, I saw lots of errrors like this: Oct 05 23:55:35 mail.[redacted] dovecot[1053]: imap(samuel@[redacted])<10580><JUizN/WwWGKX0qt0>: Error: Mailbox INBOX: UID=364587: read(zlib(/srv/mail/[redacted]/samuel/mail.mdbox/storage/m.10688)) failed: read(/srv/mail/[redacted]/samuel/mail.mdbox/storage/m.10688) failed: Broken pipe (FETCH BODY[]) Oct 05 23:55:35 mail.[redacted] dovecot[1053]: imap(samuel@[redacted])<10580><JUizN/WwWGKX0qt0>: FETCH read() failed in=140 out=1440544 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=1 body_bytes=467441 I have been using xz compression for a long time and it has been reliable. However, the latest update seemed to corrupt some attachments. So, I downgraded back to: warning: downgrading package dovecot (2.3.11.3-2 => 2.3.10.1-2) warning: downgrading package pigeonhole (0.5.11-1 => 0.5.10-2) Now, I see a different error message: Oct 06 00:13:38 mail.[redacted] dovecot[833]: imap(samuel@[redacted])<4019><efc9ePWwgiOX0qt0>: Error: Corrupted record in index cache file /srv/mail/[redacted]/samuel/mail.mdbox/mailboxes/INBOX/dbox-Mails/dovecot.index.cache: UID 364587: Broken virtual size in mailbox INBOX: read(zlib(/srv/mail/[redacted]/samuel/mail.mdbox/storage/m.10688)): FETCH BODY[] got too little data: 467441 vs 475397 1/ Why did this happen and is there a safe way to upgrade? 2/ Is downgrading a temporary solution? 3/ Are these files lost or can I rebuild them somehow? Kind regards, Samuel

Dsync issues since 2.3.11.3.
by Reio Remma 02 Oct '20

02 Oct '20

Hello! I've started seeing intermittent dsync failures since upgrading Dovecot to 2.3.11.3-3 (CentOS 8 using the official Dovecot repo). Sep 27 17:49:04 host dovecot[130]: dsync-local(user@host)<5GWFD2CmcF+TJwAAsNnMGQ>: Warning: Failed to do incremental sync for mailbox INBOX, retry with a full sync (Modseq 66543 no longer in transaction log (highest=66547, last_common_uid=46346, nextuid=46347)) Sep 27 17:49:04 host dovecot[130]: dsync-local(user@host)<5GWFD2CmcF+TJwAAsNnMGQ>: Error: Remote command returned error 75: ssh <options> doveadm dsync-server -u user@host It seems to happen at random times to random users. My setup has 2 servers - users are connecting to the main server and the secondary server is just for backup - noone is actually connecting to it. Any suggestions? Thanks! Reio
