How do I make "vnd.dovecot.environment" available?
by Graham Leggett 08 Oct '20

08 Oct '20

Hi all, According to the docs at https://wiki.dovecot.org/Pigeonhole/Sieve, some extensions are not available by default. The docs tell me the sieve_plugins, sieve_extensions and/or sieve_global_extensions configs are involved, but I can find no authoritative documentation as to what the values should be. What values must I use to make “vnd.dovecot.environment” available? Adding "sieve_global_extensions = +vnd.dovecot.environment” to 90-sieve.conf seems to not be enough.

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>

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

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.
