Android mail client capable of utilizing FTS?
by Alexander Skwar 22 Apr '25

22 Apr '25

Hello I enabled FTS Full Text Search using Tika in dovecot and have all the emails now reindexed. Using either "IMAP by hand" (ie via telnet or openssl s_client), SOGo webmail, or Thunderbird on macOS, I can search for and also find emails based on text which is only in a PDF attachment. Using Thunderbird or the now dead k-9, I'm not finding anything. Can someone maybe suggest an email client for Android which is able to find emails based on text in FTS? Technically, I guess it should do a "search TEXT "foo bar"" query.

Dovecot migration to new server with namespace issues
by Gabriel Kaufmann | TYPOworx 22 Apr '25

22 Apr '25

Hello, I'm trying to migrate old ispconfig server with dovecot + postfix to a new modernized server. I'm having some trouble with dovecot doing what I want/need to reuse use my old configuration. I've been using maildir++. The new dovecot makes me some headcache as I cannot simply reuse the old configuration or INBOX folder. Any ideas how to get this fixed? My Maildir's & IMAP looked like this for the old system: Maildir/ <-- obviously not shown in IMAP :) INBOX/ Drafts/ Templates/ Sent/ Archives/ Trash On my old ispconfig server with older linux/dovecot version I simply had this configuration: > namespace inbox { > inbox = yes > > mailbox ".Drafts" { > auto = no > special_use = \Drafts > } > mailbox Drafts { > auto = subscribe > special_use = \Drafts > } > > mailbox ".Junk" { > auto = no > special_use = \Junk > } > mailbox Spam { > auto = no > special_use = \Junk > } > mailbox Junk { > auto = subscribe > special_use = \Junk > } > > mailbox ".Trash" { > auto = no > special_use = \Trash > } > mailbox Trash { > auto = subscribe > special_use = \Trash > } > > mailbox Archives { > auto = subscribe > special_use = \Archive > } > } My approach to make this work using dovecot 2.3.21 got me in some trouble. Obviously new dovecot wants to store INBOX-Date in Maildir/{cur,tmp,new} instead of Maildir/INBOX?

Bash automation for Dovecot
by Travis Bean 21 Apr '25

21 Apr '25

Hello, I developed a Bash script to automate the installation and configuration of open-source software (i.e., launchpad.net/linuxha) I want to make sure the syntax of this script is perfect so I can use it as a teaching tool to educate people about Linux. I need to know if there is anything misconfigured with my Dovecot syntax. If you find a bug in LinuxHA, please submit a bug report to bugs.launchpad.net/linuxha/+filebug. Kind regards, Travis Bean Hello, I developed a Bash script to automate the installation and configuration of open-source software (i.e., launchpad.net/linuxha) I want to make sure the syntax of this script is perfect so I can use it as a teaching tool to educate people about Linux.

Problem email client iPhone ios18.2
by andrzej.milewski＠gmail.com 17 Apr '25

17 Apr '25

Hello, I have a fairly new installation of the Dovecot server version 2.3.19.1 on Debian 12.8. In general, the server works correctly. It sends and receives emails without issues. The clients primarily use Thunderbird on desktops and Gmail on Android. However, some clients are using iPhones with various hardware versions. Those with iOS below version 18 work correctly without any issues. Those who have updated their phones to version 18 and now even 18.2 are experiencing problems with mailbox synchronization. On version 18.2, the issue appears as follows: When you open the app, you can read several messages. They load correctly, but, for instance, attachments do not. If I wait for some time, the attachment eventually loads. During this time, I observe the server logs, and it shows that a certain session on the Dovecot server has ended. Dec 17 13:13:01 iredmail0 dovecot[408]: imap(xxx(a)xxx.com)<44785><1QGZCHcp/+3AqM2O>: Disconnected: Connection closed (UID SEARCH finished 92.295 secs ago) in=2972 out=6076956 deleted=0 expunged=0 trashed=0 hdr_count=0 hdr_bytes=0 body_count=36 body_bytes=6059064 Dec 18 08:40:41 iredmail0 dovecot[408]: imap(xxx(a)xxx.com)<177412>: Disconnected: Connection closed (UID FETCH finished 90.079 secs ago) in=5126 out=1304237 deleted=0 expunged=0 trashed=0 hdr_count=94 hdr_bytes=289688 body_count=89 body_bytes=969615 Dec 18 08:42:19 iredmail0 dovecot[408]: imap(xxx(a)xxx.com)<177410><D5mqU4cpZ+nAqM2O>: Disconnected: Connection closed (UID FETCH finished 95.051 secs ago) in=4475 out=1162785 deleted=0 expunged=0 trashed=0 hdr_count=95 hdr_bytes=281674 body_count=61 body_bytes=839545 Dec 18 08:44:17 iredmail0 dovecot[408]: imap(edyta.kowalewska(a)laktopol.com.pl)<177918>: Disconnected: Connection closed (UID FETCH finished 92.132 secs ago) in=29399 out=30266644 deleted=0 expunged=0 trashed=0 hdr_count=565 hdr_bytes=1726228 body_count=628 body_bytes=28109455 After the session is closed, the attachment loads immediately. From the logs and router analysis, it appears that the download happens in another previously opened session. After this incident, I go to another message with an attachment, and the situation repeats. There are also situations where the email body does not load, and the app waits for the server until the session closes and the content is fetched in another session. It does not matter whether I connect to the server via the internet or through a local network. On an iPhone 7 with iOS 15.8.3, everything works smoothly. Attachments open without issues. On iOS 18.1.1, attachments do not load, and the session does not close on its own. It takes forever unless the app is closed. In the Gmail app, everything works correctly without any issues. This is clearly a problem with the mail client on iPhone. However, is there anything I can adjust in my server settings to mitigate this issue for users?

Decouple the username hash from the login given
by José Celestino 16 Apr '25

16 Apr '25

Hi all, Is there a way to do the hash on the director without setting the user (or destuser) for the Dovecot backend authentication? The scenario is: Our accounts have multiple aliases where each alias can have a different password (long story): Alias1 accountX password1 Alias2 accountX password2 Alias3 accountX password3 accountX accountX passwordX Our goal is to map the same account, regardless of the alias used to authenticate, to the same backend server. We use checkpassword for userdb on the director, and when we set either the user or username to the main account id (accountX on the example) it sends the authentication as accountX, passwordN, and fails. Is there a var that can be set and used for hashing, leaving the authentication untouched? Our installed version is 2.3.21. Thank you. Best regards, José Celestino

Question about dovecot quota calculation
by Zakaria 16 Apr '25

16 Apr '25

Hi everyone, I wondered if anyone know the reason why dovecot quota command:- doveadm quota get -u email_address returns slightly smaller size than status command vsize:- doveadm mailbox status -t all "*" -u email_address I wondered if its a bug, if not it would be noticeable imparity between the two results? given in my case dovecot leaves out around 67 MB through quota command? I think both should present identical results, anyone thinks otherwise, I would appreciate if you share with us the reasoning? Also, which one I should use to determine if user exceeded quota limit for certainty? Any recommendation? With thanks. Zak.
