UID Purge?
by Kevin 28 Mar '17

28 Mar '17

Hi, I've just migrated to Dovecot from cyrus-imapd, and I notice that when I move emails from one folder to another they appear to be automatically marked deleted (expected) and also purged (not expected). With cyrus, I am used to emails being marked deleted, but still existing until a manual purge (expunge). Is this normal behaviour with Dovecot, and is it configurable? Thanks. Kevin.

One way dsync replication with dsync -R
by Wolfgang Hennerbichler 24 Mar '17

24 Mar '17

Hi dovecot users, I’ve found the -R parameter for dsync. Does this enable one-way syncing if enabled on the slave in replication_dsync_parameters? The documentation doesn’t mention much what happens if I enable this on the “replciation slave”. Before you ask: Two way synchronisation causes issues in my installation (see the unanswered thread here: http://www.dovecot.org/list/dovecot/2017-March/107431.html) it causes unread, deleted messages to re-appear. I would hope that one-way … [View More]

FTS on shared/virtual folders
by Daniel Miller 24 Mar '17

24 Mar '17

A question on how FTS is implemented with regards to shared & virtual mailbox. In particular - with Solr. Does Dovecot treat each shared and virtual mailbox as completely independent - which means Solr would reindex each appearance independently? If that's the case, has any thought been given to potentially identifying such queries and passing them to Solr against the "native" or private mailboxes that are referenced? -- Daniel

"Connection queue full" error
by Mark Moseley 24 Mar '17

24 Mar '17

Just a quickie: why is "Connection queue full" logged under Info, instead of something like error? Or at least have the word 'error' in it? Seems like a pretty error-ish thing to happen. Anything that causes the connection to fail from the server side should show up in a grep -i for error. I.e. I don't care about clients failing to match up SSL cipher suites; that's fine as Info (SSL errors ironically do have 'error' in them, though I assume that's coming from the ssl libs). But the server … [View More]

dsync with namespaces
by Tom Sommer 23 Mar '17

23 Mar '17

I have a major dsync headache which I am hoping someone can help me with. I have to migrate mails from a 'namespace/inbox/prefix=INBOX.' server to a 'namespace/inbox/prefix=' server. So I'm trying # dsync -o 'namespace/inbox/prefix=' sync -1 -f -u xx(a)xx.com tcp:1.2.3.4 It works fine for some accounts, however for others many hundreds and sometimes thousands of mails go missing from the destination inbox, and a resync doesn't pick them up. The debug output doesn't recognize these … [View More]

dovecot configuration oops
by Liam Parker 23 Mar '17

23 Mar '17

Hi, I've just transitioned from using courier to dovecot. Thanks for making this possible. During the 'quite simple' transition process, I didn't do much prep as I'm in more of a more of a fix-compile-fix-compile mode rather than a 'read all the docs first' so you may just want to give up now :) If you are still with me, I just wanted to say, it wasn't completely obvious that I needed a password and a user database [PAM not virtual]. Maybe that's just me but anyway, I spent longer … [View More]
